How to Regrow Hair on Bald Spots Naturally: 7 Science-Backed Methods

Noticing a bald spot can be a distressing experience, often triggering a frantic search for solutions. While pharmaceutical treatments like Minoxidil are widely known, many individuals prefer a holistic approach before turning to chemical interventions. The good news is that science increasingly supports several natural methods for stimulating dormant hair follicles and improving scalp health.

Regrowing hair naturally requires two things: patience and consistency. Unlike “miracle cures” advertised online, science-backed natural methods work by optimizing the biological environment of the scalp, reducing inflammation, and increasing blood flow. Below, we explore seven evidence-based strategies to help you reclaim your hair health.

1. Targeted Scalp Massage and Physical Stimulation

One of the simplest yet most effective ways to encourage hair growth is through mechanical stimulation. Scalp massages aren’t just for relaxation; they physically stretch the cells of hair follicles. According to a study published in Eplasty, standardized scalp massages can increase hair thickness by stimulating the dermal papilla cells.

How to do it: Use your fingertips (not nails) to apply firm, circular pressure to the bald spot for at least 4 to 5 minutes daily. This process encourages vasodilation, ensuring that oxygen and nutrients reach the hair bulb more efficiently.

2. Rosemary Oil: The Natural Alternative to Minoxidil

Rosemary essential oil has gained significant traction in the scientific community. A landmark study compared rosemary oil to 2% minoxidil (a common hair growth drug). After six months, both groups showed a significant increase in hair count, but the rosemary oil group reported less scalp itching and irritation.

Application Tip: Never apply pure essential oil directly to the skin. Mix 3–5 drops of rosemary oil with a carrier oil—such as pumpkin seed oil or jojoba oil—and massage it into the affected area. Leave it on for at least 30 minutes before washing.

3. Onion Juice for Alopecia Areata

While the scent is off-putting to some, onion juice is a powerhouse for hair regrowth. It is rich in sulfur, a mineral required for the production of enzymes and proteins (like keratin). Research published in the Journal of Dermatology found that participants with alopecia areata who applied onion juice to their scalp twice daily saw significantly more regrowth than those using tap water.

Why it works:

Sulfur Content: Supports strong, thick hair shafts.

Antimicrobial Properties: Helps fight scalp infections that may contribute to hair loss.

Catalase Production: May help reduce hydrogen peroxide buildup at the follicle.

4. Nutritional Optimization: Feeding the Follicle

Your hair is a non-essential tissue, meaning your body sends nutrients to vital organs first. If you have a deficiency, your hair follicles are the first to suffer. To regrow hair on bald spots, you must address internal deficiencies.

Nutrient	Role in Hair Care Growth	Food Sources
Iron	Carries oxygen to hair cells.	Spinach, lentils, red meat.
Zinc	Plays a role in hair tissue growth and repair.	Pumpkin seeds, oysters, chickpeas.
Biotin (B7)	Produces keratin.	Eggs, sweet potatoes, almonds.
Protein	The building block of the hair strand.	Greek yogurt, lean meats, tofu.

5. Aloe Vera for Scalp Health

Aloe vera has been used for centuries to treat hair loss. It works primarily by soothing the scalp and unblocking hair follicles that may be clogged by excess oil (sebum) or dead skin cells. Aloe vera also contains proteolytic enzymes which repair dead skin cells on the scalp, creating a healthier environment for new growth.

How to use: Apply pure aloe vera gel to your scalp and bald spots 2–3 times a week. Let it sit for an hour before rinsing with a mild shampoo.

6. Stress Management and Cortisol Control

High levels of cortisol (the stress hormone) can push hair follicles into a “resting” phase, known as telogen effluvium, where they stop producing new strands. While this is often temporary, chronic stress can prevent bald spots from recovering.

Incorporating adaptogens like Ashwagandha or practicing daily mindfulness can lower systemic inflammation. When your body feels “safe” and well-rested, it can divert resources back to “luxury” functions like hair production.

7. Ginseng Supplements

Ginseng contains active components called ginsenosides, which have been shown to promote hair growth by stimulating hair follicles. Scientific reviews suggest that ginseng can inhibit the 5-alpha reductase enzyme, which is responsible for converting testosterone into DHT (the hormone primarily responsible for male and female pattern baldness).

Before starting any supplement, consult with a healthcare provider to ensure it doesn’t interfere with existing medications.

Pros & Cons of Natural Hair Care Regrowth Methods

Choosing the natural route is a commitment. It is important to weigh the benefits against the limitations to manage your expectations effectively.

Pros:

Fewer Side Effects: Natural methods rarely cause the scalp irritation, headaches, or unwanted facial hair growth sometimes associated with pharmaceuticals.

Cost-Effective: Ingredient Education like onion juice, rosemary oil, and scalp massage are significantly cheaper than clinical treatments.

Holistic Health: Improving your diet and reducing stress benefits your entire body, not just your scalp.

Cons:

Slower Results: Natural methods typically take 3 to 6 months of daily consistency before visible changes appear.

Variable Efficacy: What works for one person’s biology may not work for another’s.

Odor and Texture: Some treatments (like onion juice or oils) can be messy or have strong smells.

When to See a Doctor

While natural methods are effective for many, some types of hair loss require medical intervention. If you notice sudden, patchy hair loss, redness, scaling, or if the hair loss is accompanied by fatigue or other systemic symptoms, consult a dermatologist. Conditions like scarring alopecia or thyroid-related hair loss need professional diagnosis and specific treatments to prevent permanent damage.

Frequently Asked Questions

How long does it take to see results from natural hair growth methods?

Typically, it takes 3 to 6 months to see visible regrowth. Hair Care grows in cycles, and it takes time for a follicle to move from the resting phase back into the active growth phase.

Can I use rosemary oil and onion juice together?

Yes, you can alternate these treatments. However, it is best to introduce one at a time to ensure your scalp does not have an adverse reaction to either ingredient.

Does biotin really regrow hair on bald spots?

Biotin is highly effective if you have a biotin deficiency. If your levels are already normal, taking extra biotin may not significantly speed up growth, though it can improve the strength of the hair that does grow.

Are bald spots permanent?

It depends on the cause. If the hair follicle is still alive (common in thinning or alopecia areata), regrowth is possible. If the follicle has been replaced by scar tissue (scarring alopecia), natural regrowth is much more difficult.

Does drinking more water help hair growth?

Hydration is essential for overall cell function, including the cells in your hair follicles. Dehydration can make hair brittle and dry, which leads to breakage, though water alone will not “cure” a bald spot.

Vitamin E Oil for Hair Growth: Science-Backed Tips for Thicker Hair

The pursuit of thicker, more resilient hair often leads us to expensive salon treatments and complex chemical formulas. However, one of the most effective tools for hair vitality is a potent antioxidant that has been a staple in skincare for decades: Vitamin E. While it is often praised for its ability to heal skin, its role in scalp health and hair follicle support is backed by both traditional use and emerging scientific perspectives.

Vitamin E is not a single compound but a group of fat-soluble vitamins with powerful antioxidant properties. When applied to the hair and scalp, it acts as a protective shield against the stressors that lead to thinning and breakage. In this guide, we will explore the science behind Vitamin E for hair growth and provide actionable steps to integrate it into your routine safely.

The Skincare Science: How Vitamin E Supports Hair Care Growth

To understand how Vitamin E aids hair growth, we must first look at the environment in which hair grows: the scalp. Hair Care loss and thinning are often linked to oxidative stress, a condition where free radicals damage the cells within the hair follicles.

Reducing Oxidative Stress

Research suggests a strong correlation between oxidative stress and alopecia. Vitamin E is a rich source of tocotrienols, a specific group of antioxidants. A notable study demonstrated that participants who took Vitamin E supplements over an eight-month period saw a 34.5% increase in hair count, largely due to the reduction of lipid peroxidation and oxidative stress on the scalp.

Improving Scalp Circulation

Healthy blood flow is essential for delivering oxygen and nutrients to the hair follicles. Vitamin E has been shown to support capillary health. By improving the micro-circulation of the scalp, it ensures that the “root” of the hair is well-nourished, which can lead to faster and thicker growth cycles.

Balancing Oil Production

Vitamin E creates a protective barrier on the skin’s surface. This helps lock in moisture and prevents the overproduction of sebum (oil). A balanced scalp—one that is neither too dry nor too oily—provides the ideal foundation for healthy hair to thrive without the risk of clogged follicles or fungal issues like dandruff.

Key Benefits of Vitamin E Oil for Your Hair Care

Enhanced Shine: By replacing the protective lipid layer on the outside of the hair cuticle, Vitamin E restores luster and reduces the “dull” look caused by environmental damage.

Prevention of Hair Care Loss: By stabilizing the hair follicle environment, it can slow down the shedding process associated with oxidative damage.

Split End Repair: While it cannot “fuse” a split end back together, it strengthens the hair shaft, making it less prone to splitting and breakage in the future.

Soothing Scalp Irritation: Its anti-inflammatory properties help calm redness and itching associated with dry scalp conditions.

How to Use Vitamin E Oil Safely and Effectively

Vitamin E oil is highly concentrated and can be quite heavy. To get the best results without weighing your hair down or causing irritation, follow these expert-recommended application methods.

1. The Scalp Massage (Carrier Oil Blend)

Never apply pure Vitamin E oil directly to the scalp in large quantities, as it can be difficult to wash out and may cause contact dermatitis in sensitive individuals. Instead, blend it with a carrier oil like coconut, almond, or jojoba oil.

Mix 2–3 drops of Vitamin E oil with 1 tablespoon of your chosen carrier oil.

Gently massage the mixture into your scalp using your fingertips for 5–10 minutes.

Leave it on for at least 30 minutes before washing with a mild shampoo.

2. The Shampoo Boost

If you have oily hair and fear that a direct oil treatment will be too heavy, you can fortify your existing products. Add a few drops of Vitamin E oil to your dose of shampoo or conditioner during your shower. This provides a “flash treatment” that protects the hair during the cleansing process.

3. Dietary Intake

Topical application is excellent for immediate shine and scalp health, but “internal” Vitamin E is what fuels the hair follicle long-term. Focus on a diet rich in:

Leafy greens (spinach and kale)

Nuts and seeds (sunflower seeds and almonds)

Vegetable oils (olive oil and sunflower oil)

Avocados

Vitamin E vs. Other Popular Hair Care Oils

Choosing the right oil depends on your specific hair needs. Here is how Vitamin E compares to other common treatments:

Oil Type	Primary Benefit	Best For
Vitamin E Oil	Antioxidant protection & Scalp health	Thinning hair & Scalp issues
Rosemary Oil	Stimulating circulation	Androgenetic alopecia
Castor Oil	Rich in Ricinoleic acid	Thickening existing strands
Argan Oil	Deep hydration	Frizzy or heat-damaged hair

Pros & Cons of Using Vitamin E for Hair Care

While Vitamin E is a powerhouse nutrient, it is important to weigh the advantages against the potential drawbacks to ensure it is the right fit for your hair type.

Pros

Accessibility: Vitamin E capsules and oils are affordable and available in most pharmacies.

Versatility: It can be used as a pre-shampoo treatment, a leave-in serum, or a dietary supplement.

Scientific Backing: Unlike many “fad” ingredients, the antioxidant benefits of Vitamin E are well-documented in clinical dermatology.

Cons

Texture: Pure Vitamin E oil is very thick and “tacky,” which can be difficult to distribute through fine hair.

Sensitivity Risk: Some users may experience a rash or allergic reaction if the oil is not properly diluted.

Delayed Results: Hair Care growth is a slow process; it typically takes 3 to 6 months of consistent use to see visible changes in thickness.

Safety Precautions and Professional Advice

Before starting a Vitamin E regimen, keep the following safety tips in mind. Always perform a patch test by applying a small amount of diluted oil to the inside of your elbow and waiting 24 hours to check for any adverse reactions.

If you are considering Vitamin E supplements, consult with a healthcare professional first. Excessive intake of fat-soluble vitamins can lead to toxicity, which may ironically lead to more hair loss rather than growth. Topical use is generally considered safe for most people, but moderation is key.

Frequently Asked Questions

Can I leave Vitamin E oil in my hair overnight?

Yes, you can leave a diluted Vitamin E oil blend in your hair overnight. However, it is recommended to wrap your hair in a silk scarf or use a protective pillowcase, as the oil can be messy. If you have an oily scalp, an overnight treatment may be too heavy; 30 minutes to an hour is usually sufficient.

Does Vitamin E oil work for receding hair lines?

Vitamin E can help improve the health of the skin and follicles in the area of a receding hairline, but it is not a cure for genetic pattern baldness. It works best as a preventative measure and as a way to support the growth of existing follicles by reducing oxidative damage.

How often should I use Vitamin E oil on my hair?

For most hair types, a scalp treatment once or twice a week is ideal. Overusing oil can lead to buildup on the scalp, which may block follicles and hinder hair growth. Always ensure you are washing the oil out thoroughly with a clarifying or balancing shampoo.

Can I poke a Vitamin E capsule and put it directly on my hair?

While you can use the oil from a supplement capsule, it is extremely concentrated and sticky. It is much more effective to mix that oil with a carrier oil like jojoba or almond oil before applying it to your scalp and hair to ensure even distribution and easier removal.

10 Best Hair Growth Serums for Black Hair: 2024 Expert-Tested Picks

Navigating the journey toward longer, thicker hair often feels like a marathon, particularly for those with textured, curly, or coily hair. Black hair is uniquely beautiful but also structurally delicate, requiring specific nutrients and moisture-rich formulas to thrive. Factors like tension from protective styles, scalp dryness, and hormonal changes can often lead to thinning edges or stagnant growth.

A high-quality hair growth serum isn’t just about “magic” in a bottle; it’s about creating the optimal environment for the scalp to function at its best. By stimulating blood flow, blocking DHT (a hormone linked to hair loss), and providing essential hydration, the right serum can transform your hair care routine. We have curated and tested the ten best hair growth serums specifically formulated to address the needs of Black hair in 2024.

Understanding the Needs of Black Hair Care and Scalp Health

Black hair typically has a more elliptical follicle shape, which makes it harder for natural scalp oils (sebum) to travel down the hair shaft. This leads to dryness and potential breakage. When looking for a growth serum, it is crucial to find a balance between stimulating active ingredients and nourishing carriers that won’t clog pores or cause buildup.

Key Ingredient Education to Look For

Rosemary Oil: Often compared to minoxidil in its efficacy for increasing blood circulation to the scalp.

Peptides: Small proteins that help strengthen the hair follicle and improve hair density.

Castor Oil: Rich in ricinoleic acid, it helps lock in moisture and has anti-inflammatory properties.

Biotin: A B-vitamin that supports the production of keratin.

Caffeine: Known to extend the “anagen” (growth) phase of the hair cycle.

10 Best Hair Care Growth Serums for Black Hair Care: 2024 Top Picks

Product Name	Key Benefit	Best For
Mielle Rosemary Mint Scalp & Hair Care Oil	Affordable & Effective	Protective Styles & Edges

This viral sensation remains a top pick for 2024. Infused with biotin and over 30 essential oils, it is particularly effective for those wearing braids or weaves. The cooling sensation of mint provides instant relief to a tight scalp while rosemary works to invigorate the follicles.

2. Vegamour GRO Hair Care Serum

Vegamour uses phyto-actives to revitalize hair roots. For Black women experiencing shedding due to stress or postpartum changes, this serum is a game-changer. It is water-based, meaning it won’t leave a greasy residue on your silk press or curls.

3. Pattern Beauty Scalp Serum

Designed by Tracee Ellis Ross specifically for textures 3B to 4C, this serum focuses on scalp wellness. It features peppermint, rosemary, and lavender oils. It’s a “breath of fresh air” for a dry scalp, reducing inflammation that can hinder growth.

4. The Ordinary Multi-Peptide Serum for Hair Care Density

If you prefer a science-forward, lightweight formula, this is it. It contains REDENSYL and Procapil, which target the stem cells and human fibroblasts from the dermal papilla to improve hair density without the heavy feel of traditional oils.

5. The Mane Choice Multi-Vitamin Scalp Nourishing Growth Oil

This product is packed with Vitamins A, C, D, and E. It is heavy enough to seal in moisture for 4C hair types but formulated to be absorbed quickly enough to stimulate the scalp without causing “itchy” buildup.

How to Apply Serums for Maximum Results

Consistency is the most important factor when using a growth serum. To see real results, follow these expert tips:

Target the Scalp, Not the Hair Care: Focus the product directly on the skin. Use a dropper or your fingertips to ensure the product reaches the follicles.

The 4-Minute Massage: After application, massage your scalp in circular motions for at least four minutes. This manual stimulation increases blood flow, helping the serum penetrate deeper.

Use on Damp Scalp: While many serums can be used on dry hair, applying them to a clean, slightly damp scalp after washing can sometimes improve absorption.

Avoid Overloading: A few drops go a long way. Using too much product can lead to clogged pores (folliculitis), which can actually inhibit hair growth.

Pros and Cons of Using Hair Care Growth Serums

Pros and Cons

Pros

Targeted Treatment: Allows you to focus on specific problem areas like thinning edges or the crown.

Scalp Health: Most serums include anti-fungal or anti-inflammatory ingredients that reduce dandruff.

Improved Texture: Regular use often results in softer, more manageable new growth.

Versatility: Most can be used while wearing protective styles.

Cons

Time Investment: Results typically take 3 to 6 months of daily or consistent use.

Potential for Buildup: Oil-based serums may require more frequent clarifying washes.

Cost: High-end clinical serums can be expensive over time.

Frequently Asked Questions

How long does it take to see results from a growth serum?

Hair Care typically grows about half an inch per month. Most users begin to see noticeable “baby hairs” or increased density after 90 days of consistent application. Patience and a regular routine are essential.

Can I use these serums while wearing braids?

Yes. In fact, using a serum while in braids is highly recommended to keep the scalp hydrated and to prevent tension-related hair loss. Look for serums with a dropper or a pointed nozzle for easy access between the braids.

Do I need to wash my hair more often when using a serum?

If you are using an oil-based serum (like Mielle or Camille Rose), you should use a clarifying shampoo every 1–2 weeks to prevent buildup. Water-based serums (like The Ordinary or Vegamour) usually do not require more frequent washing.

Is it better to apply serum at night or in the morning?

Nighttime application is often preferred. During sleep, the body undergoes a repair process, and the serum has several hours to absorb without being disturbed by styling products or environmental pollutants.

Will these serums help with traction alopecia?

Serums can help stimulate follicles that are dormant, but they cannot “regrow” hair in areas where the follicle has been permanently scarred. For early-stage traction alopecia, these serums can be very effective when combined with low-tension styling.

Expert Final Thoughts

Choosing the best hair growth serum for Black hair requires understanding your specific scalp needs. Whether you choose a botanical oil blend or a clinical peptide solution, the key is the health of the scalp. By combining these top-rated products with a healthy diet and low-manipulation styling, you can maximize your hair’s natural growth potential in 2024.

Onion Juice for Hair Regrowth: Side Effects and Essential Safety Tips

The quest for thicker, fuller hair often leads people back to nature. Among the many DIY remedies circulating on social media and wellness forums, onion juice has emerged as a frontrunner. While the idea of applying vegetable juice to your scalp might seem unconventional, its roots are firmly planted in traditional medicine and supported by preliminary scientific research.

However, natural does not always mean harmless. While onion juice can be a potent ally for hair health, it is chemically intense due to its high sulfur content. Without proper application and safety precautions, this “kitchen miracle” can lead to significant scalp irritation and discomfort. To help you navigate this home remedy safely, we’ve broken down the potential side effects and essential safety protocols you need to know before you start your treatment.

The Skincare Science Behind Onion Juice for Hair Care

Before diving into the risks, it is important to understand why people use it. Onions are rich in dietary sulfur, an element found in amino acids that are components of keratin—the protein that makes up our hair. Proponents suggest that the sulfur in onion juice provides the building blocks for stronger hair, boosts blood circulation to the follicles, and may even minimize thinning.

A small study published in the Journal of Dermatology indicated that participants with alopecia areata who applied onion juice twice daily saw significantly more hair regrowth than those who used tap water. Despite these promising signs, the high concentration of active compounds means the scalp must be treated with care.

Potential Side Effects of Onion Juice

While many people use onion juice without issues, others may experience adverse reactions. The skin on our scalp is sensitive, and the acidic nature of onions can be disruptive.

1. Scalp Irritation and Redness

The most common side effect is localized irritation. Sulfur is a powerful element, and in its raw form, it can cause a burning sensation, itching, and visible redness. This is particularly common in individuals with sensitive skin or those who leave the juice on for too long.

2. Contact Dermatitis (Allergic Reactions)

Even if you aren’t allergic to eating onions, you may have a topical sensitivity. Contact dermatitis can manifest as an itchy rash, hives, or even small blisters. If your scalp feels excessively hot or starts to swell after application, you are likely experiencing an allergic response.

3. Dryness of the Hair Care and Scalp

Onion juice is an astringent. While this is great for those with oily scalps, it can strip away the natural oils (sebum) that protect the hair shaft. Overuse can lead to a dry, flaky scalp and hair that feels “crunchy” or brittle to the touch.

4. Eye Irritation

The same sulfurous compounds (syn-propanethial-S-oxide) that make you cry when chopping onions can irritate your eyes during application. If the juice drips down your forehead or into your eyes, it can cause intense stinging, watering, and temporary redness.

5. The Lingering Odor

While not a medical side effect, the psychological impact of the smell is a real concern. The pungent sulfur scent can linger in the hair for days, even after multiple washes with fragrant shampoos. This is often exacerbated when the hair becomes wet or sweaty.

Essential Safety Tips for Application

To reap the benefits of onion juice while minimizing the risks mentioned above, follow these expert-recommended safety tips.

Perform a Patch Test First

Never apply onion juice to your entire scalp without testing it first. Apply a small amount of the juice to the skin behind your ear or on your inner elbow. Wait 24 hours to see if any redness, itching, or irritation develops. If your skin reacts, do not use it on your scalp.

Always Dilute the Juice

Raw onion juice is highly concentrated. To make it gentler, mix it with a soothing carrier agent. Popular options include:

Aloe Vera Gel: Calms the scalp and adds moisture.

Coconut Oil: Provides a protective barrier and helps neutralize the acidity.

Honey: Acts as a humectant to prevent dryness.

Limit the Duration

Beginners should not leave onion juice on their scalp overnight. Start by leaving it on for 15 to 30 minutes. If your scalp tolerates it well, you can gradually increase the time, but most experts recommend washing it out within an hour to avoid extreme dryness.

Use Fresh Juice Only

Onion juice oxidizes quickly. To ensure the nutrients are active and to prevent the growth of bacteria, always prepare a fresh batch for each use. Do not store leftover juice in the refrigerator for more than 24 hours.

Pros and Cons of Onion Juice for Hair Care Regrowth

Comparing the benefits against the drawbacks can help you decide if this treatment fits your lifestyle.

Pros	Cons
Cost-effective and accessible.	Extremely pungent and persistent odor.
Rich in sulfur to support keratin.	High risk of scalp irritation or stinging.
Antimicrobial properties help with dandruff.	Messy and time-consuming application.
May stimulate dormant hair follicles.	Results require consistent, long-term use.

Who Should Avoid Onion Juice?

While it is a popular remedy, it is not for everyone. You should avoid onion juice if:

You have a known allergy to onions, garlic, or leeks.

You suffer from chronic scalp conditions like psoriasis or seborrheic dermatitis (consult a dermatologist first).

You have open sores, scratches, or broken skin on your scalp, as the juice will cause severe burning.

You have recently undergone a chemical treatment (like a perm or bleach), as the scalp may be too sensitive.

Frequently Asked Questions (FAQ)

How often should I use onion juice for hair growth?

Consistency is key, but moderation is vital for safety. Most people find success using the treatment 2 to 3 times per week. Daily use is generally discouraged as it can lead to chronic scalp irritation and excessive dryness.

How can I get rid of the onion smell after treatment?

To neutralize the odor, rinse your hair with a diluted apple cider vinegar solution or lemon juice after shampooing. Using a shampoo with a strong citrus or peppermint scent also helps. Some users find that adding a few drops of rosemary or lavender essential oil to the onion juice mixture helps mask the smell from the start.

Does onion juice work for all types of hair loss?

Onion juice is most effective for thinning caused by nutrient deficiencies or conditions like alopecia areata. It is less likely to be effective for permanent hair loss caused by scarring or advanced androgenetic alopecia (male/female pattern baldness). If you are experiencing rapid, unexplained hair loss, it is best to see a doctor for a formal diagnosis.

Can I use onion juice on colored hair?

Generally, onion juice is safe for color-treated hair, but because it is acidic, it could potentially cause some colors to fade faster. It is always wise to do a test on a small, hidden strand of hair first to ensure it doesn’t affect your specific hair dye.

Can onion juice cause hair to fall out?

In rare cases, if the scalp becomes severely inflamed or if the hair becomes extremely dry and brittle due to over-application, breakage can occur. However, onion juice does not typically cause the follicle to stop producing hair unless a severe allergic reaction occurs. Always follow dilution and timing guidelines to prevent damage.
