Yeast infection of the scalp caused by Pityrosporum Ovale results in dandruff. This further results in a collection of dry and scaly skin on the scalp. If not treated on time, such a build-up causes hair fall and interferes with new hair growth too.

An interesting research found that a shampoo containing 5% tea tree oil was effective against dandruff. Tea tree oil possesses anti-fungal activity that fights against Pityrosporum ovale.

In this study, 26 individuals used the shampoo containing tea tree oil daily for 4 weeks and the results showed 41% improvement. It was further reported that use of such a shampoo decreased the scaliness, along with greasiness and itchiness, which are the common features of the hair and scalp affected by the fungus.

Furthermore, it also prevents unwanted hair fall and hair loss. No side-effects or toxic effects were observed in the study, thus, it can be concluded that tea tree oil, when used in moderation, is safe to use.

Reduces Hirsutism

Hirsutism is a clinical feature of PCOS, where excess hair is present on the face, chest, and back of the females. This is due to the presence of excess male sex hormones (androgens) in females.

A scientific study conducted in 2012 found that lavender oil and tea tree oil possess anti-androgenic activities. Applying these oils twice a day for 3 months reduced hirsutism or male pattern hair growth in females.

It reduced the hair diameter and females were able to get rid of unwanted hair. Another advantage of tea tree oil was that it did not alter the hormones or have a negative effect on them. Hence, tea tree oil can be considered safe and economical to use.

    • Coconut oil
    • Almond oil
    • Olive oil
  • Add 10-12 drops of tea tree oil to the carrier oil and mix well. The amount of tea tree oil, however, depends upon the length of your hair.
  • You can even combine tea tree oil with lavender oil or peppermint oil to further enhance the benefits.
  • For a dry and itchy scalp, mix a few drops of tea tree oil with jojoba oil. Massage this oil gently and leave it for 30 minutes. Wash your hair using a mild shampoo.
  • For soft, smooth and lustrous hair, mix tea tree oil with warm olive oil. Apply this oil mixture on your scalp and hair and repeat this procedure at least for a month for amazing results.
  • For long, strong and thick hair, mix tea tree oil with almond oil. Apply it properly on your entire hair and scalp and wash your hair after 30 minutes. Repeat this procedure at least 3 times a week for best results.
  • To battle dandruff and flaky scalp make your own tea tree oil shampoo. Add a few drops of this oil to your existing shampoo. Shampoo your hair and leave this tea tree oil and shampoo mixture on your hair for 3 to 5 minutes. This will help the oil to reach your hair, its roots, and the damaged scalp. The oil will then fight against the fungus and work towards eradicating it. Rinse the shampoo from your hair and follow this procedure regularly.

Note: The above-mentioned procedures will show effective results only when they are done properly and regularly. Irregular application of tea tree oil will not show an improvement or any beneficial results. Tea tree oil is not helpful for individuals with hair loss associated with aging, chemotherapy or an autoimmune condition.
