4MAS Hair Building Fibers are made from natural Keratin of the highest quality giving an instant appearance of a thick and full head of hair.
Keratin is the same type of protein found in real hair which makes it look natural once applied. Also, it has an innate static charge that ensures the 4MAS Hair Building Fibers resists wind, rain and perspiration. It is so resistant, even its colorfast fibers won’t run or rub off on clothes or pillows.
This product is also perfect for covering both gray roots and color-treated root re-growth!
Keep the natural look for a longer period of time by using a Holding Spray! The fibers are easily removed when wetting and shampooing your hair.
