Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Tea Tree oil (Melaleuca alternifolia) is widely used to support hair and scalp health. Its use is primarily justified by scientific evidence, although some traditional use exists as well. Several clinical studies and laboratory investigations have explored Tea Tree oil's antifungal, antibacterial, and anti-inflammatory properties. Specifically, Tea Tree oil has demonstrated efficacy against Malassezia species, the fungi implicated in dandruff and seborrheic dermatitis, both of which are common scalp conditions. A notable randomized controlled trial published in the Journal of the American Academy of Dermatology (Satchell et al., 2002) found that a 5% Tea Tree oil shampoo significantly improved dandruff symptoms compared to placebo. Additionally, Tea Tree oil is used in various formulations aimed at reducing scalp inflammation and itchiness.

However, while Tea Tree oil's antimicrobial effects are well-documented, evidence for its ability to promote hair growth or prevent hair loss is limited and mostly anecdotal. Most scientific support focuses on scalp health rather than direct effects on hair shaft or follicle. Furthermore, Tea Tree oil can cause allergic reactions or irritation in some individuals, so it should be used with caution and typically diluted in carrier oils or shampoos. Overall, scientific evidence supports Tea Tree oil’s use for maintaining scalp health, particularly in managing dandruff and minor scalp irritations.
