Made with cotton — not keratin. YLO fibers are natural cotton, colour-bonded with mineral pigments. They cling to the hair you already have to add visible fullness, then wash out with shampoo. What you see is what's in the bottle.
Covered by standard 30-day returns · Free US shipping · Ingredients: natural cotton fibers, iron oxide mineral pigments.
