tea tree oil scalp: Antimicrobial Benefits, Endocrine Concerns, and Why Eucalyptus Is the Better Choice for Hair Oil

Tea tree oil is one of the most popular scalp treatment ingredients globally. Its antimicrobial properties are well-documented. But it has two significant concerns that exclude it from Vihira 360°: endocrine disruption potential and high sensitisation risk.

What Tea Tree Oil Does

• Terpinen-4-ol + 1,8-cineole: Documented antifungal activity against Malassezia furfur at 0.25–1%.

• 2002 study: 5% tea tree oil shampoo significantly reduced dandruff severity vs placebo.

• Antibacterial against Cutibacterium acnes — relevant for scalp folliculitis.

Why Tea Tree Is Not in Vihira 360°

• Endocrine disruption: In vitro studies suggest weak oestrogenic/anti-androgenic activity. European Commission flagged for endocrine disruption review under cosmetics regulation.

• Sensitisation: One of the highest contact dermatitis rates of any essential oil, particularly when oxidised. Indian climate accelerates oxidation.

• Eucalyptus Globulus Leaf Oil: Equivalent Malassezia control, better tolerability, no endocrine disruption concerns.
