7 Best Essential Oils for Hair Growth (1)

Thinning hair, slow growth, or excessive shedding—these aren’t just frustrating; they can shake your confidence. The good news? Essential Oils for Hair Growth are more than just a trend—they’re backed by science and trusted by experts for their ability to stimulate follicles, improve scalp health, and strengthen every strand from root to tip.

The Best Essential Oils for Hair Growth

1. Rosemary Oil

Rosemary oil is one of the most potent natural solutions for hair regrowth. It directly improves blood circulation to the scalp, allowing hair follicles to receive more oxygen and nutrients.

How It Works:

Dr. Michael R. Hamblin, a researcher at Harvard Medical School, has extensively studied how rosemary oil boosts cellular metabolism in hair follicles.

He explains that rosemary oil improves microcapillary perfusion, ensuring hair receives the maximum amount of nutrients needed for rapid growth.

Applying a few drops of rosemary oil mixed with a carrier oil (like coconut or jojoba oil) to your scalp before bed can have a significant impact over time.

2. Peppermint Oil

Peppermint oil creates a cooling sensation, which isn’t just refreshing—it increases scalp circulation and stimulates hair follicles directly.

Research published in Toxicological Research shows that peppermint oil significantly increases hair follicle count, depth, and thickness.

How It Works:

Dr. Young Chul Kim, a South Korean researcher specializing in dermatology, discovered that peppermint oil increases IGF-1 (insulin-like growth factor 1), a protein crucial for hair follicle development.

This means your follicles stay in the active growth phase for longer, resulting in thicker and fuller hair over time.

Mix 3-4 drops of peppermint oil with argan oil and massage it into your scalp three times a week.

3. Lavender Oil

Stress-related hair loss is real, and lavender oil directly addresses this issue. In addition to promoting hair growth, it has calming effects that reduce cortisol (stress hormone) levels.

Since high cortisol disrupts the hair growth cycle, lavender oil prevents shedding and supports consistent regrowth.

How It Works:

Dr. Tiffany Field, a researcher at the University of Miami, conducted a study showing that inhaling lavender oil reduces cortisol levels by 27%.

Since stress is a major contributor to hair loss, using lavender oil both topically and aromatically ensures that your hair stays in the growth phase for longer.

For added benefits, diffusing lavender oil before bed ensures a relaxed nervous system, keeping hair follicles healthy.

4. Cedarwood Oil

Cedarwood oil is one of the most effective essential oils for reversing hair thinning caused by poor circulation or scalp conditions like dandruff.

It has natural antibacterial and antifungal properties, ensuring your scalp remains clean and free from blockages that hinder hair growth.

How It Works:

A 1998 study published in Archives of Dermatology found that cedarwood oil, when combined with rosemary and thyme, significantly improved hair regrowth in alopecia areata patients.

The study concluded that cedarwood improves follicle function by preventing excess sebum buildup and microbial overgrowth on the scalp.

Adding cedarwood oil to your shampoo or mixing it with a scalp serum can help reset your scalp’s health.

5. Tea Tree Oil

A healthy scalp is essential for hair growth, and tea tree oil ensures follicles remain unclogged and free from excess oil, dandruff, and bacteria.

Its antiseptic properties create the ideal environment for new hair strands to grow without obstruction.

How It Works:

Dr. Phillip Artemi, a dermatologist from the Australasian College of Dermatologists, emphasizes that tea tree oil has “powerful antimicrobial properties that eliminate yeast and fungal overgrowths—common causes of scalp inflammation and hair loss.”

Adding 2-3 drops of tea tree oil to your shampoo clears dandruff and prevents buildup that blocks hair follicles.

6. Clary Sage Oil

For those struggling with weak or brittle hair, clary sage oil is essential. It contains linalyl acetate, a compound that strengthens hair strands and prevents premature breakage.

How It Works:

A study published in Advanced Pharmaceutical Bulletin shows that clary sage oil significantly improves keratin production, making hair strands stronger and more resistant to damage.

Mix a few drops of clary sage oil into your leave-in conditioner or deep conditioning treatment to reinforce your hair structure.

7. Ylang-Ylang Oil

If your scalp tends to be dry, ylang-ylang oil restores hydration while promoting hair growth. A well-moisturized scalp leads to healthier, more resilient hair.

How It Works:

A study from the Journal of Dermatological Science highlights that ylang-ylang oil increases scalp sebum production, ensuring optimal hydration levels for follicle function.

Those with naturally dry hair or a flaky scalp benefit from adding ylang-ylang oil to a warm oil treatment once a week.

How to Use Essential Oils For Hair Growth?

To see real results, consistency is key. Essential oils should be diluted with a carrier oil (such as coconut, jojoba, or argan oil) before applying them to the scalp.

  • Scalp Massage (3-4 times per week): Mix 5-6 drops of your chosen essential oil with a carrier oil and massage into your scalp for 5-10 minutes. Leave it on for at least 30 minutes before washing.
  • Shampoo Booster: Add 2-3 drops of essential oil to your regular shampoo to enhance its effectiveness.
  • Overnight Treatment: For deep nourishment, leave the oil on overnight and wash it out in the morning.

Hair growth isn’t about waiting for results—it’s about taking action with the right ingredients. Essential oils for hair growth have been scientifically proven to improve follicle function, increase circulation, and strengthen hair from the root.
