Infused with Iris Root extract and a blend of 5 vitamins including vitamin E, the serum deeply penetrates the fiber over 8 hours for 100% absorption to restore hair's balanced nutrition levels. Its lightweight creamy texture suits all hair types: on fine hair it helps detangling and provides a better manageability on normal to coarse hair. Applied at night, hair progressively absorbs the nutrients of the nourishing serum to reverse daytime depletion. This milky-gel like cream melts into the hair to be quickly absorbed. The next morning, hair looks nourished and is visibly softer, easier to style, with a lightweight satin finish.
