Essential Oils for Facial Hair Removal: What the Evidence Says

Short answer: No essential oil has been shown to remove facial hair or stop it from growing in good-quality human trials. The best evidence is a single small trial in which a lavender and tea tree oil spray made hairs slightly thinner in women with mild hirsutism and normal hormone levels^[1]. Essential oils can make your skin feel soothed after hair removal, but they can also irritate it, and treatments that actually reduce hair growth are available from a doctor^[2].

If you search for natural ways to get rid of facial hair, you will find lists of “hair-stopping” essential oils: lavender, tea tree, grapefruit, spearmint, fennel, nut grass and more. Many of these lists are written to sell oils. We looked for the actual studies behind each claim, and this article sums up what we found, including grapefruit, tea tree and lavender oil.

A quick note on terms: hirsutism is coarse, dark hair growing in a male-like pattern on a woman’s face, chest, back or stomach. It is usually driven by androgens, a group of hormones that includes testosterone. The most common cause is PMOS (formerly PCOS), short for polyendocrine metabolic ovarian syndrome, the new name for polycystic ovary syndrome^[2]. If you are not sure whether your hair growth counts as hirsutism, try our hirsutism self-check.

Essential oils for hirsutism at a glance

Here is our summary of the evidence for the oils most often recommended for facial hair. The labels describe evidence for reducing hair growth, not for scent or for soothing skin.

Oil	What people claim	What the research shows	Evidence
Lavender + tea tree (together)	Slows hair growth, anti-androgenic	One small open-label trial (24 women, mild idiopathic hirsutism): thinner hairs and a lower hirsutism score after 3 months, no change in hormones[1]	Limited
Lavender (alone)	Soothing, slows hair growth	No hair studies of lavender on its own	None
Tea tree (alone)	Antibacterial, slows hair growth	No hair studies of tea tree on its own	None
Fennel	Anti-androgenic	One small trial of a 3% fennel gel (an extract, not pure essential oil) found thinner facial hairs after 24 weeks[3]	Limited
Nut grass (Cyperus rotundus)	Works like laser hair removal	One open-label pilot study on underarm hair from a single author, not independently repeated[4]	Limited
Spearmint oil	Lowers testosterone	Studies used spearmint tea, not oil[5][6]	None (for the oil)
Grapefruit	Removes hair, “contracts” skin	No studies on hair. Cold-pressed citrus oils can make skin react badly to sunlight[7]	None
Chamomile, lemongrass, frankincense	Soothing, astringent	We found no studies on hair growth	None
Turmeric	Anti-androgenic	We found no studies of turmeric on facial hair in women	None

Can essential oils remove facial hair or stop it from growing?

Essential oils cannot remove hair. Hair removal means taking the hair shaft out (shaving, waxing, threading, tweezing, creams) or damaging the follicle so it stops making hair (laser or electrolysis). Rubbing an oil on your skin does neither.

The more realistic question is whether an oil could slow hair growth or make hairs finer over time. Hirsutism hairs grow because androgens act on sensitive hair follicles. A few plant oils have shown anti-androgen activity in lab tests, which is why they get recommended. But a lab result is not the same as less hair on your chin. In the few human studies we found, the measured effects were small, the studies were short and small, and none showed that hair stopped growing^[1][3][4].

For context, the Endocrine Society’s hirsutism guideline, the main clinical guideline for doctors, suggests against using topical anti-androgens (creams that block male hormones in the skin) for hirsutism, because they haven’t been shown to work well enough^[2]. That guideline does not cover essential oils at all.

The essential oils, one by one

The lavender and tea tree oil study

Evidence: Limited Almost every essential oil article on hirsutism points to the same study. Researchers in Italy randomly assigned 24 young women with mild idiopathic hirsutism to spray either a lavender and tea tree oil mix or a placebo on their hirsute areas twice a day for 3 months^[1]. “Idiopathic” means the women had excess hair but normal hormone levels and regular periods.

In the oil group, the hirsutism score and the diameter of the hairs went down, and hairs got thinner by a bigger percentage than in the placebo group. Blood hormone levels did not change in either group^[1]. The authors called the results preliminary.

Why we rate this as limited:

• Only 12 women used the oil.
• The study was open-label, meaning the women and researchers knew who got which spray, which can bias how results are scored.
• The main change was thinner hairs, not fewer hairs or hair that stopped growing.
• It only included mild hirsutism with normal hormones. It tells us nothing about PMOS or more severe hair growth.
• As far as we could find, it has not been repeated by other researchers.

Does lavender oil help with hirsutism?

Evidence: None We found no studies of lavender oil on its own for hirsutism or facial hair. The only hair evidence is the combined lavender and tea tree spray above^[1]. The U.S. National Center for Complementary and Integrative Health (NCCIH) says the evidence for lavender is limited across the board and that topical lavender products can cause allergic skin reactions in some people^[9].

Many women like using a diluted lavender product after shaving or waxing because it smells pleasant. That is a fine personal choice. Just don’t expect it to change how fast your hair grows.

People often ask whether organic lavender oil is better. We found no research comparing organic and conventional lavender oil for skin. What matters more for your skin is freshness: lavender oil oxidizes when exposed to air, and oxidized lavender oil is a known cause of contact allergy^[11].

Does tea tree oil help with hirsutism?

Evidence: None As with lavender, there are no hair studies of tea tree oil on its own. You may read that adding tea tree oil to your lotion will “help inhibit the growth of future hair”. We could not find any evidence for that.

Tea tree oil is studied mainly for skin infections and acne, and even there the NCCIH describes the evidence as limited^[10]. Some women use a diluted tea tree product on the skin after hair removal, hoping to calm razor bumps. That is not proven either, and tea tree oil can cause redness and irritation, especially when the oil is old or has been exposed to heat, light or air^[10]. If you get frequent bumps, see our guide to preventing and treating razor bumps and ingrown hairs.

Never swallow tea tree oil. Taken by mouth it can cause confusion, unsteadiness, inability to walk and even coma^[10].

Does grapefruit essential oil remove hair?

Evidence: None No. We found no studies of grapefruit oil on hair growth, and there is no plausible way for it to remove hair. Grapefruit oil comes from the peel of the fruit. A 2018 review of citrus essential oils found that oils pressed from citrus peel (“expressed” or cold-pressed oils) carry a low to moderate risk of phototoxicity, while steam-distilled citrus oils do not^[7]. The problem comes from natural chemicals called furanocoumarins.

Phototoxicity means that skin coated with the oil reacts badly to sunlight. The skin can become red and inflamed and may blister 24 to 48 hours after sun exposure, and dark marks can stay for years afterward, often more noticeably in darker skin^[8]. That is the last thing you want on your face. If you use a product with cold-pressed citrus oil, keep it off skin that will be in the sun. The 2018 review recommends avoiding sun for at least 12 hours if more than the recommended maximum amount has been used on the skin^[7].

Does spearmint essential oil work like spearmint tea?

Evidence: None Spearmint is the best-studied herb for hirsutism, but the research used spearmint tea, not essential oil. A 5-day study in 21 women and a 30-day randomized trial in 42 women with PCOS (now PMOS) found that drinking spearmint tea twice a day lowered free testosterone^[5][6]. In the longer trial, women felt their hair had improved, but the doctor-rated hair score did not change significantly^[5].

We found no studies showing that rubbing spearmint oil on your face has the same effect. Read our full guide to spearmint for hirsutism for details on the tea studies.

Does fennel help with facial hair?

Evidence: Limited Fennel has some of the better evidence on this list, although it’s still thin. In a randomized, placebo-controlled trial in Iran, 44 women with mild to moderate idiopathic hirsutism applied either a 3% fennel gel or a placebo gel for 24 weeks^[3]. Facial hair thickness in the fennel group fell from about 98 to 76 micrometers, while it rose slightly in the placebo group. Itching and irritation were reported in both groups^[3].

Keep in mind that this was a gel made with fennel extract at a set strength, not a few drops of fennel essential oil. The study measured hair thickness, not how many hairs grew, and the authors themselves called for larger, longer studies^[3].

Does nut grass oil work like laser hair removal?

Evidence: Limited Nut grass oil (Cyperus rotundus) is marketed as a natural alternative to laser. The claim comes from a 2014 pilot study in which 65 people with unwanted underarm hair were randomly assigned to the oil, a saline (salt water) control, or alexandrite laser, and 60 finished. The author reported no significant difference between the oil and the laser, and a better result with the oil for white hairs^[4].

The study was open-label, had a single author and looked at armpits, not faces. We found no independent trial confirming it. We cover it in detail in our article on nut grass essential oil for hair removal.

Chamomile, lemongrass and frankincense

Evidence: None These oils appear on many hair removal lists because they are described as soothing, calming or astringent. We found no studies on any of them for hair growth or hirsutism. If you like their scent in an aftercare product, that’s up to you, but they won’t change your hair.

Turmeric

Evidence: None Turmeric is usually used as a powder in face masks rather than as an essential oil. Claims that it is anti-androgenic and reduces facial hair are common online, but we found no studies of turmeric on facial hair in women. Turmeric powder can also temporarily stain the skin yellow, especially on lighter skin.

How to use essential oils safely on your skin

Essential oils are highly concentrated plant chemicals. Natural does not mean harmless, and freshly shaved or waxed skin is more easily irritated. If you choose to use them, these practical steps reduce the risk:

• Always dilute. Never put undiluted (“neat”) essential oil on your face. Mix a small amount into a plain, fragrance-free lotion, gel or carrier oil, or use a ready-made product. More is not better.
• Patch test first. Apply a little of the diluted mix to a small patch of skin, such as the inside of your forearm, and wait a day or two before using it on your face.
• Use fresh oil. Keep bottles closed, cool and away from light, and throw away old oil. Oxidized lavender and tea tree oil are more likely to cause skin reactions^[10][11].
• Avoid broken skin. Wait until any nicks, cuts or raw patches from hair removal have healed.
• Keep citrus oils out of the sun. Cold-pressed grapefruit, lemon, lime and bergamot oils can cause phototoxic burns^[7][8].
• Never swallow essential oils. They are not the same as herbal tea^[10].
• Stop if your skin reacts. Redness, itching, burning or a rash can be a sign of allergic contact dermatitis. Lavender oil, once oxidized, is one of the more common essential oil allergens: in one study, 2.8% of patients tested for suspected skin allergies reacted to it^[11].

Are lavender and tea tree oil hormone disruptors?

This question comes up a lot, and it deserves a careful answer. In 2007, doctors described three boys, aged about 4 to 10, who developed breast tissue growth (gynecomastia) before puberty while using products that contained lavender oil, or lavender and tea tree oil, such as a balm, a styling gel and shampoo, and soap and lotions. In each case the breast growth went away after the products were stopped^[12]. In lab tests on cells, both oils acted weakly like estrogen and blocked the effect of androgens^[12].

These were case reports in three children, not a study that proves cause and effect, and other ingredients in the products weren’t tested^[12]. The NCCIH notes that it is unclear whether lavender was responsible for the breast swelling reported in children^[9]. Interestingly, the women in the lavender and tea tree hirsutism trial had no change in their blood hormone levels^[1].

Our practical take: there is no evidence that these oils harm adult women’s hormones at normal cosmetic use. But if you use them, keep your products away from young children, especially boys before puberty, and don’t apply them to children’s skin without asking a doctor.

Can you use essential oils after shaving, waxing or sugaring?

Yes, as long as they are diluted and your skin tolerates them. Many women find a gentle, scented aftercare routine makes hair removal feel less like a chore. Just keep expectations realistic: any benefit is comfort and fragrance, not slower regrowth.

Online you will find recipes for gels, sprays, chickpea-turmeric masks and sugar wax with essential oils. Here is what is worth knowing:

• Aftercare gel or spray: A plain aloe vera gel or a gentle, fragrance-free moisturizer is enough on its own. If you add an essential oil, use only a small amount and patch test.
• Sugar wax: Homemade sugar wax made from sugar, lemon juice and water removes hair from the root, like regular waxing. Adding an essential oil only changes the smell, and lemon juice and citrus oils on freshly waxed skin can sting. Let the wax cool to a safe temperature before you apply it.
• Face masks: A mask can feel nice, but it will not reduce hair growth. Turmeric may stain the skin.

What actually reduces unwanted facial hair?

If you want less hair, not just softer skin, these options have far better evidence than any essential oil:

• Hormonal birth control pills. Evidence: Strong The Endocrine Society suggests them as the first treatment for most women with hirsutism who are not trying to get pregnant^[2].
• Anti-androgen medicines such as spironolactone. Evidence: Strong These are usually added if the pill alone isn’t enough after 6 months. They must be combined with reliable contraception because they can harm a developing baby^[2].
• Laser hair removal and electrolysis. Evidence: Strong The guideline suggests laser (photoepilation) for brown or black hair and electrolysis for white or blonde hair^[2].
• Eflornithine cream (a prescription cream that slows facial hair growth). Evidence: Moderate It can be added to laser treatment for a faster response^[2].

Medical treatments take time. The guideline recommends trying a treatment for at least 6 months before changing it^[2]. See our guides to hirsutism medication and permanent hair removal with laser, IPL and electrolysis.

When to see a doctor

Unwanted facial hair is often a sign of an underlying hormone condition, most commonly PMOS, so it’s worth getting checked rather than relying on home remedies alone. See a doctor soon if you notice any of the following. Sudden or fast-worsening hair growth and signs of virilization (a deepening voice, an enlarged clitoris, more muscle) can point to a rare androgen-producing tumor, and irregular periods are a common sign of an underlying hormone condition^[2]:

• Hair growth that starts suddenly or gets worse quickly over a few months
• A deepening voice
• An enlarged clitoris
• Increasing muscle mass
• Irregular or missing periods

Frequently asked questions

Which essential oil stops facial hair growth permanently?

None. No essential oil has been shown to stop hair growth, permanently or temporarily, in good human trials. The best study, of a lavender and tea tree spray, found slightly thinner hairs in 12 women with mild hirsutism^[1]. For permanent reduction, laser hair removal and electrolysis are the proven options^[2].

Does grapefruit essential oil remove hair?

No. There are no studies showing it affects hair, and cold-pressed citrus oils can cause burns and dark marks on skin exposed to sunlight^[7][8].

Can I put tea tree oil on my face after shaving?

You can if it is well diluted and you have patch tested it, but it won’t slow regrowth. Tea tree oil can irritate the skin, especially if it is old or has been exposed to air, light or heat^[10]. Never use it undiluted, and never swallow it.

Is lavender oil safe to use if I have young children?

For adults, normal cosmetic use is generally considered acceptable, though some people get allergic skin reactions^[9]. Because of case reports linking lavender and tea tree products to breast growth in young boys, it’s sensible to keep these products off children’s skin^[12].

What is the best natural remedy for facial hair?

Spearmint tea has the most research among natural options, but even there the evidence for less hair is limited^[5][6]. See our guide to supplements for hirsutism for the full picture.

Key takeaways

• No essential oil removes facial hair or has been shown to stop it from growing in good human trials.
• The best evidence is one small, open-label trial of a lavender and tea tree spray that made hairs slightly thinner in women with mild hirsutism and normal hormones.
• Fennel gel and nut grass oil each have one small study, and grapefruit, chamomile, lemongrass, frankincense and turmeric have none.
• Essential oils can irritate skin, cause allergies, and (for cold-pressed citrus oils) burn in the sun. Always dilute and patch test, and keep them away from young children.
• For real hair reduction, talk to a doctor about the pill, anti-androgens, laser or electrolysis.
