Keep it thicker! Designed to help those with thinning hair restore the full and even appearance of healthy hair in seconds, our Fiber Hair Thickener Collection offers four natural-looking shades – Grey, Medium Brown, Light Brown, Dark Brown/Black – to deliver instant scalp coverage, recreate the natural appearance of healthy volume, and help eliminate visibly thinning areas of hair loss. Coupled with KERABOND Technology, a proprietary, high-performance keratin formulation designed to replenish keratin, fortify strands, and protect from future damage, the results are shiny, stronger, more manageable, thicker, healthy hair.
