These hair fibers are a game changer! I have thinning hair on top and after applying these you literally can’t tell. They stay all day even through light rain.

Tried many hair fiber brands before and Lex Signature Line is the best. Natural look, no residue on fingers, and the applicator pump is so convenient.
