Green Tea
Studies show that green tea might help with hair regrowth and growth. Green tea is made from dried fresh Camellia sinensis plant leaves and contains high levels of antioxidants. The primary antioxidants that green tea has include flavonoids, particularly catechins. Since green tea contains antioxidants, its extracts improve hair health and prevent hair loss.
In a minor study, experts applied topical EGCG extract from green tea to the scalps of three alopecia patient participants. When four days have passed, the participants show improvement in their hair growth. The study suggests that EGCG escalates hair growth by preventing hair and skin cell damage and stimulating hair follicles.
In addition, a study of hair loss in mice shows that after six months, 33 percent of the animals that took green tea extract showed hair regrowth. On the other hand, no mice within the control group showed an increase in hair growth.
However, using green tea supplements for hair growth should still be done with caution. It is also uncertain how effective and fast green tea hair treatments help boost hair growth in people, particularly those with hair loss associated with hormones.
