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.


All KERATHERAPY Home Care Collections feature our exclusive KERABOND Technology which combines keratin with each product’s specific group of organics, botanicals, amino acids, and conditioning agents. This super-conditioning complex is delivered to the areas of the hair where they are needed the most.
