Tea tree oil is known for its antifungal properties, and, as dandruff is often caused by fungal infestation, using tea tree oil for dandruff has long been one of the much-touted dandruff remedies. That said, the research conducted on the subject isn't exactly conclusive; in some cases, the tea tree oil had been found effective, and in others it doesn't seem to have made much of a difference. It may be a good idea to also try out other natural dandruff remedies like olive oil or coconut oil, and go with what works the best; these oils are also strongly anti fungal.
One of the main causes of dandruff is a yeast-like fungus called Pityrosporum ovale, also known as Malassezia globosa. The growth of this fungus is generally aided by poor hygiene, stress, hormonal imbalance and other health issues, and it feeds on the sebaceous secretions and causes scalp inflammation. This causes the scalp to itch and eventually flake.
There are many tea tree oil for dandruff shampoos that are specially formulated for both preventing dandruff and treating dandruff. It is a good idea to check the ingredients list when buying; the tea tree oil for dandruff shampoo should contain at least five percent tea tree oil to be effective. It is also possible to buy tea concentrated tree oil separately and mix it with the regular shampoo to wash the hair.
If using separately, massage the tea tree oil to the scalp and leave on for about 20 minutes before shampooing. With a tea tree oil for dandruff shampoo, lather it in and let sit for about five minutes before rinsing off. This tea tree oil for dandruff remedy should, preferably, be carried out at least three times a week for good results.
It is advisable, particularly for people with sensitive skin or those prone to allergies, to do a skin patch test before using tea tree oil; some people have had allergic reactions to the oil. The concentrated form of tea tree oil in particular can be quite strong and lead to skin irritations. Diluting it with olive oil or coconut oil is definitely recommended.
The tea tree oil should never be ingested as it is quite toxic. It can impair the immune system and the central nervous system, and it has also be known to cause hormonal imbalances. If there is any vomiting, diarrhea or drowsiness after using this product, please consult a doctor. Pregnant and breastfeeding women are advised to avoid using this oil or its products, and look instead for other, more safer natural dandruff remedies.
