What It Is
Green tea is made from the fresh leaves of Camellia sinensis. Unlike fermented tea varieties, it undergoes minimal oxidation during processing to retain its rich native polyphenols, especially EGCG (epigallocatechin gallate). As a classic botanical ingredient, it is widely added to natural shampoo bars and hair‑care formulas.
Mechanism of Action
- Powerful antioxidant activity from EGCG Catechins in green tea neutralise free radicals triggered by UV rays, pollution and heat styling. They prevent oxidative damage to hair proteins and the scalp barrier.
- Regulate scalp sebum secretion Green tea compounds help balance sebaceous gland activity, easing oily scalp without stripping essential moisture.
- Soothe scalp micro‑inflammation It reduces redness and irritation on sensitive scalps, maintains a healthy scalp microbiome and relieves itching.
- Protect hair follicles Active ingredients support the micro‑environment of hair follicles, slowing oxidative stress that may weaken hair roots.
Benefits for Hair

Rooted in Tradition, Emerging in Science
Green tea has a millennia‑long heritage in East Asian culture. Originally valued as a wellness beverage in ancient China, it was later used in folk rituals for external cleansing. People rinsed hair with green‑tea infusions to refresh the scalp, reduce greasiness and bring a natural shine, forming a time‑honoured botanical beauty practice.
Scientific Evidence
- Laboratory studies confirm EGCG is a potent antioxidant that eliminates free radicals to protect scalp and hair keratin.
- Cosmetic research shows green‑tea extracts help regulate sebum production, improving oily‑scalp conditions.
- In‑vitro tests demonstrate its anti‑inflammatory properties, which relieve scalp irritation and support a balanced scalp ecosystem.
- Multiple hair‑care studies verify green‑tea polyphenols help preserve follicle vitality against oxidative stress.
