Black Tea Extract Theaflavins Benefits

Black Tea Extract for Hair（Loss）

• Black tea extract, abundant in theaflavins, can eliminate free radicals on the scalp to reduce oxidative stress-induced damage to hair follicles, thereby preserving follicular vitality and delaying follicular aging.
• Meanwhile, it can effectively inhibit local inflammatory responses on the scalp, improve scalp microcirculation, ensure an adequate supply of nutrients and oxygen to hair follicles, and optimize the microenvironment for hair growth.
