Flat, lifeless hair results from each strand being so smooth and fine that it lays quite literally flat, one on top of the other. Full Thickening Cream is a lightweight formula that features Poly Beta Amino Ester-1, a new technology invented by Living proof's scientists that creates a micro pattern of thickening points on each strand. Full Thickening Cream creates beautiful, natural fullness and touchable body that lasts throughout the day. Because it's a completely flexible technology, your hair won't collapse or become stiff and crunchy. Great for colored hair, too. Brand: LIVING PROOF.
