Green tea contains anti-inflammatory properties along with caffeine that acts to reduce hair loss by blocking dihydrotestosterone, a byproduct of testosterone that hinders hair follicles from producing hair. Epigallocatechin gallate (EGCG), a catechin, in green tea may prevent hair loss by inhibiting dihydrotestosterone activity that damages hair follicles, as well as improve hair texture. The caffeine from the tea helps reduce hair loss and prolong the anagen stage, the active growing stage of hair. Along with hormone activity and prolonging the growth stage, the anti-bacterial properties of green tea aids in cleansing the scalp and fighting dandruff, leaving the scalp clean for new healthy hair growth.
Besides preventing hair loss, green tea when applied to the scalp, its EGCG also aids in hair growth. The EGCG in green tea assists hair growth by giving hair follicles a boost while also protecting your scalp and hair cells from environmental stresses and sun damage with its powerful levels of antioxidants, vitamin C and vitamin E. The caffeine from green tea penetrates the hair follicles to promote growth, as well as provides stimulation and increased blood flow and nutrient delivery to the hair follicles to nourish and reduce shedding. Apart from the catechins and caffeine, the polyphenols and vitamin C present in green tea helps in boosting softness and shine in hair, and preventing hair dullness and roughness.
The main benefits for hair come from the various nutrients, amino acids, and antioxidants present. Panthenol (Vitamin B) is great to help control split ends, soften the tresses, and strengthen the roots. Direct application as well as drinking help in absorbing Vitamin B. A unique amino acid present in green tea is theanine, which works with panthenol to strengthen the hair, while Vitamin C conditions the hair to add shine and softness, achieving the healthy look that is desired by many.
