10 Best Essential Oils for Hair Growth and Scalp Health

Essential oils come from plants through processes such as distillation or evaporation. People know them best for their scent, but they also contain active compounds that may offer health-related benefits.

Traditional, Eastern, and homeopathic practices have used essential oils as natural remedies for a long time.

When you dilute them properly, some essential oils may support your hair and scalp. Keep reading to see which oils are most often discussed for hair and what they may help with.

Key Takeaways

• When properly diluted, essential oils may support scalp health, hair strength, shine, and growth.

• Rosemary, peppermint, and lavender oils have promising but still limited evidence for hair growth.

• Some oils may help with dandruff, irritation, scalp balance, or issues linked to shedding.

• Using essential oils undiluted can cause irritation, allergic reactions, burning, and skin discomfort.

10 Best Essential Oils For Hair Growth

Essential oils may lift mood, help you relax, improve focus, ease pain and inflammation, act as antiseptics, and even support immunity. They may also help your scalp feel healthier, improve hair texture, strength, and shine, and possibly reduce shedding while supporting growth.

So how might they work? In simple terms, essential oils are often described as helping stimulate blood flow in the scalp. They are considered vasodilators, which means they widen blood vessels. That matters because hair is non-essential tissue, or tissue that is no longer living.

Better circulation may help the scalp take in more nutrients. So which oils are often suggested for hair growth? Let’s look at them below.

1. Rosemary Essential Oil

Rosemary essential oil may support better hair thickness and growth because it appears to help with cellular turnover.

In the studies I reviewed, an older 2015 study found that rosemary oil performed about as well as minoxidil, a common hair growth treatment, while causing less scalp itching as a side effect. Additional studies have also looked at it in blends with other essential oils for alopecia.

Still, larger studies are needed before its benefits and use can be confirmed, especially for people without alopecia.

2. Lavender Essential Oil

Lavender essential oil is often said to support cell growth and reduce stress-related hair loss. Small human trials report that a 2016 study found lavender essential oil produced a 99.8% increase in hair growth in lab mice over three weeks.

Its antimicrobial activity may also support scalp health by limiting excess bacteria and fungi. More importantly, you can use lavender oil on the hair without wiping out the healthy bacteria that help protect the scalp from rashes and flakes.

This flexible oil is also used as a natural option for lice, although it does not kill lice eggs and needs to be combined with tea tree oil to work more effectively.

3. Cedarwood Essential Oil

Cedarwood essential oil is thought to support hair growth and reduce shedding by helping balance the scalp’s oil-producing glands. It also has antifungal and antibacterial properties, which may help with conditions tied to dandruff or hair loss.

One review notes that in several small studies discussed in a 2020 review of research, cedarwood extract used in blends with other oils appeared to reduce hair loss and improve hair growth and thickness in people with alopecia areata. Because it was not used alone, more research is still needed to know how much benefit cedarwood itself may provide.

Cedarwood oil may be harder to find at regular grocery stores, but smaller health food stores or online shops may carry it.

4. Lemongrass Essential Oil

A 2024 review of research on lemongrass essential oil suggests that a tonic with 10% lemongrass essential oil may help reduce and control dandruff. The authors say the effect may come from its antifungal activity.

Even so, larger studies are still needed before this use of lemongrass essential oil is well supported.

5. Peppermint Essential Oil

Peppermint essential oil may increase blood and nutrient flow to the scalp, which may support faster hair growth and help reduce hair loss.

It contains menthol, which creates a cooling effect that may stimulate hair follicles. Animal studies indicate that a 2014 mouse study found peppermint oil increases the number of follicles and their depth, which improved overall hair growth and thickness.

Hair products are often sold as a way to improve hair health, but too much buildup can work against growth. Treating the scalp with peppermint oil may help reduce product buildup,
which may let the hair grow with fewer obstacles.

6. Tea Tree Essential Oil

Tea tree oil has anti-inflammatory, antibacterial, and antimicrobial properties. When you use it topically, it may help support hair growth.

Early data points to some benefit because a small 2013 study found that a blend of tea tree oil, diclofenac (an anti-inflammatory), and minoxidil (Rogaine) worked better than minoxidil alone for improving hair growth.

Larger studies are still needed, though. Tea tree oil was included in that study as an anti-infective agent, so it is still unclear what benefit it may have on its own outside that blend.

Tea tree oils come in different strengths, so following the manufacturer’s directions matters. I noticed milder blends tended to feel easier on the scalp. Some products are highly concentrated essential oils, while others are already mixed into a cream or oil.

The NCCIH notes that tea tree oil has antiseptic properties and may be useful for fungal infections. However, it can also cause rashes and skin irritation.

7. Clary Sage Essential Oil

Clary sage essential oil may help strengthen the hair so it breaks less easily. It may also add more volume and contains linalyl acetate, which is linked to cell growth. Its stress-relieving properties may also support the prevention of stress-related hair loss. Along with those possible benefits, clary sage essential oil may soften hair while helping fight scalp infections.

8. Chamomile Essential Oil

Chamomile essential oil acts as a natural moisturizer that may calm the scalp and soften the hair. It also has anti-inflammatory properties and may nourish the hair, helping strengthen it and reduce damage. Like ylang-ylang oil, inhaling chamomile essential oil has been shown to reduce stress, which may help with preventing stress-induced hair loss.

You can also drink chamomile tea to support hair growth, although it may make you sleepy, so drinking it before bed may make more sense.

9. Ylang-Ylang Essential Oil

Ylang-ylang essential oil has anti-inflammatory, antimicrobial, and antioxidant properties.

A 2021 study on essential oils in cosmetics notes that ylang-ylang essential oil may help tissue regeneration.

A 2024 study suggests it may help with scalp psoriasis and dandruff. However, the purpose of that study was to develop a nanoparticle gel to improve ylang-ylang absorption rather than to test its benefits directly.

More evidence is needed before the benefits of this essential oil for hair and scalp health are clear.

10. Geranium Essential Oil

Geranium essential oil may help balance sebum production, which may reduce both dryness and excess oil. By helping regulate moisture, it may also reduce breakage and support longer, stronger hair.

The papers I saw show that a 2017 study found geranium extract increased the production of human dermal papilla cells, which are cells involved in hair follicle formation. That increase may support faster growth and thicker hair.

Risks and Potential Complications

The biggest risk with essential oils is skin irritation and allergic reactions. This is especially common when an essential oil goes directly on the skin, which is why you should always mix it with a carrier oil first.

Signs of skin irritation include:

• contact dermatitis

• burning, discomfort, or painful tingling

• discoloration in the affected area

Only older teenagers and adults should use essential oils topically for hair health. If you think essential oils may help your child, it is best to speak with their pediatrician first to make sure they are safe.

Some essential oils, including peppermint essential oil, should not be used on children’s faces because they can cause breathing difficulty.

To check for irritation, test a small amount of the mixture on a small patch of skin before using it fully. I noticed simpler test blends were easier to track for irritation.

Switch Essential Oils That Works for Hair Growth

Hair growth support only helps if your scalp can tolerate it well enough for you to stay consistent. That is the sharper standard many people miss. The most popular essential oil is not always the smartest choice by itself, especially when direct use can raise the risk of skin irritation and allergic reactions.

Real progress usually comes from choosing something active enough to support the scalp, but balanced enough to fit into regular care without turning each use into a risk. That is where the full formula matters more than the name of one ingredient.

Keyoma’s Pure Batana Oil with Rosemary offers that steadier middle ground, with rosemary supported by a richer oil base your scalp may handle more comfortably.
