If you’re on a journey to grow longer, stronger hair, without slathering your scalp in chemicals, you’re not alone. More and more people are turning to essential oils as a natural way to support hair growth, boost scalp health, and create a soothing self-care ritual that delivers results.
In this post, we’re breaking down the science and strategy behind using essential oils for hair growth. From circulation-boosting powerhouses like rosemary and peppermint to lavender and tea tree, you’ll learn which oils work best and how to use them safely and effectively.
How essential oils work for hair growth
Regarding topical treatments, essential oils are a great holistic solution for hair growth, as they offer increased circulation, reduce inflammation, and promote scalp health.
Improved blood circulation
Healthy hair growth starts at the follicle, and follicles need a steady blood supply to deliver oxygen and nutrients to the root of the hair. Certain essential oils, like rosemary and peppermint, act as vasodilators, stimulating circulation in the scalp and increasing blood flow to the follicles. Extra circulation can wake up dormant hair follicles, extend the growth phase of the hair cycle, and support stronger, thicker strands over time.
Reduce inflammation
Chronic inflammation in the scalp can prevent hair growth. It damages follicles, disrupts the hair cycle, and may contribute to alopecia. Essential oils such as lavender, clary sage, and chamomile have strong anti-inflammatory properties, calming skin and reducing oxidative stress, another known contributor to hair loss.
Promote scalp health
A healthy scalp means better hair growth. However, buildup, bacteria, and fungal overgrowth can clog hair follicles and interfere with the growth cycle. Essential oils like tea tree and eucalyptus have antifungal and antibacterial properties that help keep the scalp clean and balanced. This helps reduce flakes, itchiness, and excess oil, creating a more straightforward pathway for hair to grow without obstruction.
Top essential oils for hair growth
Several essential oils promote hair growth. Each has its own benefits and can be used to treat specific hair conditions.
- Rosemary oil is one of the most studied and common essential oils for hair growth. Some studies even found that it’s comparable to minoxidil. It’s best for improving circulation and stimulating hair follicles.
- Peppermint oil offers a cooling effect on an irritated scalp. It’s also shown to stimulate circulation, increase follicle depth, and promote hair growth.
- Lavender oil has antimicrobial and calming properties. It’s often used to support scalp health and may reduce stress-related hair loss.
- Tea tree oil offers antifungal and antibacterial properties. It helps with dandruff and scalp buildup that could block hair follicles.
- Cedarwood oil is thought to balance oil production and improve circulation. It’s sometimes used in blends to treat alopecia.
Best practices for using essential oils for hair growth
While essential oils are safe and effective treatments, there are some best practices to follow when using them to achieve your desired effect.
Dilute with a carrier oil
Essential oils are highly concentrated, so putting them on your scalp can irritate it, cause allergic reactions, or even cause chemical burns.
Use a carrier oil, such as jojoba, coconut, or argan oil, to dilute your essential oils before applying them to your scalp. A good rule of thumb is to add two to five drops of essential oil per tablespoon of carrier oil. For sensitive skin, start on the lower end.
Test for allergies
Before using an essential oil blend on your scalp, conduct a patch test to ensure you aren’t allergic to the essential oils you plan to use. Apply a small amount to your inner forearm, cover with a bandage, and wait 24 hours. If no redness or irritation appears, it’s likely safe for your scalp.
Apply directly to the scalp
Massage the oil mixture directly into the scalp, not the ends of your hair. Use clean fingertips or a dropper to apply oil along your part lines, focusing on thinning areas. Massage gently with circular motions for 3–5 minutes. Massaging not only spreads the oil but also stimulates circulation, which amplifies the growth benefits.
Let the oils sit long enough to penetrate and work, ideally at least 30 minutes before washing your hair or overnight. Always wash thoroughly with shampoo afterward to avoid buildup.
Use consistently for best results
Essential oils won’t give overnight results, but with consistent use, you may start seeing healthier hair and less shedding in six to 12 weeks. We recommend using them two to three times per week, combining them with other hair care practices such as scalp exfoliation, nutrition, and stress management.
Add to topical treatments
If you’re not into full scalp massages, try these alternatives:
- Shampoo and conditioner. Add 10-15 drops of essential oil to your shampoo or conditioner (per 8-ounce bottle). Tea tree or rosemary oil works best for this. (If you’re looking for a shampoo and conditioner with essential oils already built in, check out our Copper Chemist collection.)
- DIY hair mask. Mix with avocado, aloe vera, or egg for a DIY hair mask.
- Hot oil treatments. Warm your oil blend in a hot water bath, apply generously, and cover with a shower cap or towel. Leave on for 30-60 minutes before washing out.
- Scalp spritz or tonic. Dilute essential oils with water or rose water and witch hazel in a spray bottle. Mist lightly on scalp after showering or before styling.
Note that it’s best to avoid using essential oils if you have open wounds or active scalp infections, during pregnancy (without guidance—some oils are not safe), or if you have severe allergies or sensitivities.
Always consult a dermatologist or trichologist if you’re unsure.
