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.
Ingredients: natural cotton fibers, iron oxide mineral pigments. For external use only.
You're far from alone. After menopause, about two-thirds of women experience hair thinning. YLO adds visible fullness in seconds, so thinner areas simply look fuller.
