Get instantly thicker-looking hair with Hair Building Fibers by KeratinMD, designed to provide long-lasting, natural-looking coverage and dramatic results so you can feel the confidence that comes with a great-looking head of hair.

The pure, organic keratin hair fibers are made of the highest quality laser cut fiber with a unique complex of keratin protein. The keratin hair fibers offer a breakthrough answer for thinning hair, designed to provide the look of volume and density, long-lasting, natural-looking coverage and dramatic results for men and women.

How Do Hair Building Fibers Work?

The natural keratin Hair Building Fibers are designed to statically cling to existing hair, building each strand for thicker-looking hair. Simply sprinkle on and watch as a receding hairline, thinning areas or balding patches disappear, leaving you with thicker-looking natural hair.

Our breakthrough Hair Building Fibers are specifically designed to be undetectable. They won’t run or leave embarrassing stains on clothing or furniture.  This is because, unlike other hair thickening products, we use a unique color-locking coating. Best of all, they look completely natural in bright sunlight for any shade of hair, even hair with highlights. The fibers won’t budge through wind, rain or exercise – in fact, they won’t remove until you wash it out with shampoo.

For best results, apply your Hair Building Fibers with our Spray Applicator and set fibers with Hair Building Fibers Finishing Spray. Solidify your style with Hair Building Fibers Applicator Comb, designed with four sides for optimal styling. Our finishing spray increases the bond between our organic KeratinMD® fibers and your natural hair. Your hairstyle will last longer and look more natural, with added shine and volume.
