How Is Eucalyptus Oil Good For Hair

We have briefly discussed how eucalyptus oil can be good for your hair.

1. Improves Cortex Growth: Eucalyptus extracts boost growth in the hair cortex. They also increase beta-sheets (a form of hair protein structure) in the hair (1).

2. Increases Hair Gloss: Eucalyptus extracts, with regular use, also improve hair shine and bounce (2).

3. Helps Treat Dandruff: A 2012 study showed that eucalyptus has anti-fungal properties and can be used as an anti-dandruff agent (3). The study diluted eucalyptus oil with coconut oil and used the mixture to treat dandruff.

4. Has Antioxidant And Anti-inflammatory Properties: Eucalyptus oil contains antioxidant and anti-inflammatory properties (2). The oil may fight free radical damage and premature hair graying. It also may help soothe scalp irritation and inflammation.

5. Improves Hair Quality: In another study, eucalyptus oil was used in shampoo as an anti-fungal agent. The oil was found to nourish hair (4).

6. Promotes Scalp Health: Eucalyptus oil has antimicrobial and anti-fungal properties that keep the scalp clean and prevent fungal infections (4), (5).

7. Eliminates Head Lice: Eucalyptus oil, when paired with lemon tea tree oil, can be used in the treatment and prevention of head lice (6). The oil also contains terpenes that may help eliminate lice and its eggs (7), (8).

8. Helps Prevent Piedra: Eucalyptus oil acts against the fungus Trichosporon ovoides that causes piedra, a fungal hair infection characterized by nodules on the hair shaft (9).

9. Improves Hair Elasticity: Eucalyptus oil can increase hair elasticity and prevent hair from splitting at the ends (2). It prevents hair from breaking easily.

10. May Prevent Scalp Disorders: Eucalyptus oil may help treat scalp disorders like psoriasis, scalp pimples, and dry scalp. However, more research is warranted in this regard.

11. May Increase Blood Circulation: Eucalyptus oil may improve blood circulation and stimulate hair growth. However, research is limited in this regard.

12. May Boost Ceramide Production: Eucalyptus oil may also increase the production of ceramides. These may prevent protein loss in the hair strands. However, more research is warranted in this aspect.

13. Eucalyptus Oil Can Be Used For Hair Growth: In a study, a formulation containing eucalyptus oil stimulated hair growth (2). The oil may also prevent dandruff and improve blood flow. Another study showed that aromatherapy using essential oils like eucalyptus might prevent hair loss, stimulate hair growth, and improve overall scalp and hair health (10).

Side Effects Of Eucalyptus Oil For Hair

Eucalyptus oil may cause poisoning and show symptoms like vomiting, CNS depression, epigastric pain, nausea, contact dermatitis, hypotension, and tachycardia (13). This oil cannot be used in its concentrated form. It has to be diluted for correct usage. Inhaling eucalyptus oil may lead to seizures. It may also cause allergic reactions and skin inflammation symptoms like redness, burning sensation, bumps, and itching.

Perform a patch test before using the oil. Dilute a drop of eucalyptus oil with a teaspoon of coconut oil. Apply the mixture to a part of the forearm or behind the neck. Check for any redness, swelling, or other reactions.

You can also dilute eucalyptus oil in other ways before using it on your hair. 

How To Dilute Eucalyptus Oil For Hair

Eucalyptus oil cannot be used directly on the hair and scalp. It needs to be diluted with a base/carrier oil. You may also use jojoba oil, castor oil, almond oil, argan oil, or olive oil. Most of these oils can penetrate the hair fibers and enhance the absorption and effectiveness of eucalyptus oil.

You may also add a few drops of eucalyptus oil to your conditioner or shampoo. Such a combination may also help treat dandruff.

Conclusion

Eucalyptus oil can help improve scalp health and keep dandruff at bay. You may incorporate it into your regular hair care regimen to nourish and protect your hair. However, ensure you perform a patch test prior. Consult a doctor if you experience any adverse symptoms.
