 Remedies and treatment options

If your eyebrows are thinning, there are many ways to restore a fuller look. These options range from natural remedies to advanced professional treatments, giving you plenty of choices depending on your preferences and budget.

1. Natural remedies for eyebrow growth

While there’s limited scientific evidence that natural remedies like castor oil or aloe vera directly stimulate eyebrow hair growth, they are popular home remedies for thicker brows.

These treatments improve the health of your hair and skin, creating a better environment for eyebrow regrowth.

Many people swear by these remedies for nourishing and conditioning brows, making them worth trying if you’re looking for gentle, affordable options to restore your eyebrows naturally.

Castor Oil

  • Nourishes hair follicles with ricinoleic acid.  One study suggests that ricinoleic acid may inhibit prostaglandin D2 (PGD2), a compound linked to hair loss.
  • How to Use: Apply a small amount to your brows with a clean spoolie or cotton swab. Massage gently and leave overnight.

Onion Juice 

  • (Yes, onion juice!)  A Journal of Dermatologystudy found that onion juice stimulated scalp hair regrowth in 86.9% of alopecia areata patients after six weeks of twice-daily use. However, the study focused on scalp hair, not eyebrows
  • How to Use: Apply onion juice to brows, leave for 15 minutes, and rinse thoroughly. 

Stinging Nettle Oil

  • A study found that stinging nettle may promote eyebrow hair growth by blocking DHT (a hormone linked to hair loss), reducing inflammation, and providing essential nutrients like vitamins A, C, and iron. 
  • How to Use: Warm between fingers and apply to brows at night. Use 2-3 weekly.

Aloe Vera Gel 

  • Conditions and promotes healthy hair growth.
  • How to Use: Massage fresh aloe vera gel into brows, leave for 30 minutes, and rinse. Use 2–3 times weekly.

Coconut Oil 

  • Strengthens and conditions hair follicles.
  • How to Use: Warm between fingers and apply to brows at night. Wash. Use 2-3 weekly.

Egg Yolk Mask 

  • Repairs and nourishes with protein and biotin.
  • How to Use: Apply beaten egg yolk to brows, leave for 20 minutes, and rinse. Use 1–2 times weekly.

2. Drug free serums

If you’re looking for faster results without the risks of hormonal treatments like Latisse, try the best eyebrow serums for hair regrowth. These serums are specially designed to target thinning brows and promote natural growth.

VieBeauti Eyebrow Growth Serum

This affordable option is packed with nutrients to enhance brow growth. Many users report longer and fuller eyebrows with consistent use.

  • Why It’s Great: It works! One tube lasts several months, making it budget-friendly. And, it's safe for sensitive skin.

3. Cosmetic and Professional

If you’re looking for quick and noticeable results, cosmetic enhancements are a great way to repair overplucked eyebrows or achieve thicker brows instantly, without waiting for natural regrowth.

Here are some options:

Eyebrow Coloring

Darkening your brows is an easy way to create a fuller, more defined look. You can use a brow tinting kit or semi-permanent dye at home, or visit a salon for professional tinting services with precise results.

At-home tints typically last 2–4 weeks, while professional treatments can last longer with proper care. For safe application, always do a patch test, avoid scalp hair dye, and use petroleum jelly around your brows to prevent stains.

Note: I’ve had great results with the at-home brow dye option! I go one shade darker than my hair color but only leave it on for half the recommended time. That way, if it’s not dark enough, you can always apply more.

If you have very sparse or graying brows, dying the brows can be a quick, affordable solution to give them a fuller, polished look.

Not ready to dye your eyebrows? Try a tinted brow gel instead! It grooms, shapes, adds color, and builds fullness while filling in sparse areas with microfibers. Bonus: it can also touch up your hair roots between colorings.

Eyebrow Extensions

This is a quick way to add instant volume and fullness. A technician applies tiny hair fibers to your brows or skin with a safe adhesive placing individual strands to create a natural look. The process is painless and takes just 1–2 hours.

Extensions typically last 1–3 weeks, depending on your skin type and how well you care for them.

While they provide immediate results with no downtime, the fibers do shed over time and require regular upkeep, making them ideal for special occasions, a short-term solution.

Eyebrows Tattoos

For a long-lasting solution, eyebrow tattoos like microblading or powder brows can give you full, sculpted brows that last months or even years.

  • Microblading creates fine, hair-like strokes of pigment for a natural, subtle look, making it ideal for filling sparse areas. Results last 12–18 months.
  • Powder Brows use a machine to create a soft, shaded appearance, similar to brow makeup. This technique is best for a bold, defined look and lasts 1–3 years.

Both options offer long-lasting results, but they come with upfront costs ($300–$800) and require regular touch-ups. Choosing an experienced, licensed professional is key to avoiding scarring or uneven results.

Eyebrow Lamination

Think of this treatment like a "perm" for your brows that straightens and lifts the hairs, giving them a fuller, fluffier, and more polished look.

It’s great for uneven, thinning, or unruly brows, creating a defined, groomed look, but works best if you already have enough brow hair. Results last 4–6 weeks.

PRP Therapy 

PRP (Platelet-Rich Plasma) therapy uses plasma from your own blood, injected into the eyebrow area to stimulate hair follicle growth. This natural treatment can deliver results that last several months.

However, it is a costly option and typically requires multiple sessions for the best results, making it better suited for those seeking a long-term, professional solution.

4. Lifestyle tips to support healthy brows

In addition to remedies and treatments, adopting certain lifestyle changes can help you grow eyebrows naturally and prevent further thinning:

  • Eat a balanced diet rich in biotin, zinc, and omega-3 fatty acids to nourish hair from within.
  • Avoid harsh chemicals or excessive plucking, as they can damage hair follicles.
  • Stay hydrated and moisturize your face and brows daily to maintain healthy skin and hair.
  • Exfoliate your skin and brows regularly to clear away dead skin cells, allowing hair to grow better and keeping your skin looking fresh and healthy.

Eyebrow hair growth: My update

Thicker darker eyebrows

Last year, I started using VieBeauti Eyebrow serum.  This is one of the best eyebrow serums for hair regrowth.

I noticed my brows growing quickly—not thicker, but definitely longer—so I have to trim them about once a month. Between the serum and at-home brow tinting, I’m really happy with the results!

If overplucking or hormonal changes have caused your brows to thin, there are effective solutions to repair overplucked eyebrows and encourage regrowth.

Here are some of the most common causes of thin eyebrows:

  • Aging: Slower hair growth, hormonal changes, and less collagen contribute to thinning brows.
  • Overplucking: Frequent plucking or waxing can damage follicles, making regrowth difficult.
  • Hormonal Changes: Imbalances like hypothyroidism or menopause can cause hair loss.
  • Nutritional Deficiencies: Low biotin, iron, or zinc weakens follicles, reducing hair growth.
  • Medical Treatments: Chemotherapy, radiation, and some medications may lead to hair loss.
  • Skin Conditions: Issues like eczema or rosacea can damage skin and prevent regrowth.

If you’re unsure about what’s causing your thinning eyebrows, it may be helpful to consult a dermatologist for guidance. Knowing the root cause can help you choose the right solution to fix your brows.

Question: How long does it take to see results from natural remedies?

Answer: It can take 4–8 weeks to notice significant improvements in eyebrow thickness with consistent use of natural treatments like castor oil or coconut oil.

Question: What are some professional treatments for thin eyebrows?

Answer: Options include microblading, eyebrow lamination, PRP therapy, and extensions. These can offer quick or long-term solutions, depending on your needs.

Question: What lifestyle changes can support eyebrow regrowth?

Answer: Eat a diet rich in biotin and zinc, avoid overplucking, stay hydrated, and protect your eyebrows from harsh chemicals and excessive sun exposure.

Question: Can eyebrows grow back naturally?

Answer: Yes, eyebrows can grow back naturally in most cases, but it depends on the underlying cause. Hair follicles that haven’t been permanently damaged (e.g., from overplucking or scarring) are capable of regrowth. Natural remedies like castor oil, aloe vera, or coconut oil can nourish and condition the hair, supporting the natural growth process. A balanced diet rich in biotin, zinc, and omega-3 fatty acids also promotes healthier brows.

Question: What’s the fastest way to fix thin eyebrows?

Answer: The fastest way to fix thin eyebrows involves combining immediate cosmetic solutions with long-term care:

  • Quick Fixes: Eyebrow tinting, extensions, or lamination can provide instant volume and definition.
  • Long-Term Solutions: Use drug-free growth serums containing peptides or keratin to speed up regrowth. Consistent application of natural remedies like castor oil or coconut oil can also accelerate results.

Patience is key, as even the fastest solutions for natural growth require time to show noticeable improvements.

Question: How long does it take to regrow overplucked eyebrows?

Answer: Eyebrow regrowth can take anywhere from 4 to 8 weeks for initial results, depending on factors like age, genetics, and the extent of damage to the hair follicles. Overplucking that has caused follicular damage may take longer—several months—or may not grow back at all. Consistency in applying natural remedies, serums, or following a healthy diet is crucial for encouraging faster regrowth.

Question: Are there permanent solutions for sparse brows?

Answer: Yes, there are several permanent or semi-permanent solutions for sparse brows:

  • Microblading
  • Powder Brows
  • Eyebrow Transplants

While these options are effective, they require professional expertise and come with upfront costs and upkeep.

Question: What should I avoid when regrowing my eyebrows?

Answer: To maximize your chances of regrowth, avoid these common pitfalls:

  • Overplucking or Waxing
  • Harsh Chemicals
  • Excessive Scrubbing
  • Unhealthy Diets
  • Stress
