With options for virtually all hair colors, including gray, blonde, brown, and black, our hair thickener keratin products provide exceptional results that look and feel completely natural.

Like the other stylist-recommended keratin hair products we create, our fiber hair thickeners incorporate keratin for its power to add strength and elasticity, revive the natural protective layer, and cut down on damage and breakage. Advanced fiber technology delivers instant scalp coverage, recreating the natural appearance of healthy volume and eliminating visible thinning areas or hair loss. The easy-to-use spray bottle makes it simple to achieve the look you want, and our perfect-match color formula is designed to last until your next shampoo.
