Our Hair Roll-on Essence contains glycerin, ginseng root extract and castor oil. It activates hair follicles, nourishes hair roots, and promotes hair growth. The way to use it is very simple: wash your hair and then blow dry it. Gently roll the ball on the scalp where it needs attention to ensure an even spread. Massage gently with your fingertips until fully absorbed. It can also reduce hair loss, enhance hair toughness, and prevent hair breakage and loss.
