How Does Strand Builder Work?

Strand Builder rebuilds your hair with 100% Organic Keratin Fibers that are designed to statically cling to existing hair, building each strand for thicker-looking hair.

 Just sprinkle on and watch as your receding hairline, thinning areas or balding patches disappear, leaving you with thicker-looking natural hair. Strand Builder is specifically designed to be undetectable and won’t remove until you wash them out.

For best results, set fibers with EXT®Thermal Spray for optimal styling. Our finishing spray increases the bond between the fibers and your natural hair leaving your styling to last longer and look more natural.
