Our hair building fibers resist wind, rain, and sweat, locking your style in place until your next shampoo without running or rubbing off. | GENTLE ON YOUR SCALP: A clean alternative to keratin, our vegan hair filler is cruelty-free, dermatologist-tested, and non-irritating, making it perfect for daily use, even on sensitive skin. | THE PERFECT COLOR MATCH: Our hair fillers for thinning hair come in 14 shades. If you pick the wrong one, we offer a free shade replacement to guarantee a flawless, natural match. Pro Tip: If you're unsure between two shades, opt for the darker one. | NO MESS APPLICATION: On dry, styled hair, just shake the hair powder over areas to cover up and pat gently to set. The mess-free process gives you a thicker look without any hassle or cleanup.
