Bosley Hair Thickening Fibers are Keratin Proteins similar to natural hair. Hair Thickening Fibers blend with natural hair adding density and helping create thicker, fuller-looking hair.
Hair Thickening Fibers cover thinning hair with keratin fibers. Apply to completely dry hair by shaking liberally into thinning and low-density areas or by using the Hair Thickening Fibers Applicator Brush. Thickening Fibers come in six natural shades. Use a plastic comb to style. Shampoo to remove. If your style needs hold, use Non-Aerosol Hairspray and Fiberhold Spray. It's a medium hold and will make the Keratin Fibers durable and last longer.
