This is the Hair Building Fibers mist from Toppik. It's supposed to conceal hair loss and thinning hair and even act as a root touch-up between colorings. The mist is available in nine shades and is supposed to be water- and windproof. To use, cover the area you're filling in with the comb to avoid any fallout. Press down on the spray bottle to begin concealing the area. After only a few seconds, your hair should look completely full!<br /><br />For more, visit: <br />https://www.toppik.com/shop/hair-fiber/<br />https://www.instagram.com/toppikhair/
