Tressa FKS Functional Keratin Serum

FKS is a Functional Keratin Serum.

Bioactive technology contained in FKS helps repair, rescue, renew and protect hair. FKS has the unique ability to actually restructure the hair by imbedding proteins into the hair, providing a permanent conditioning service. This product intelligently repairs the damaged areas of the hair, eliminating frizz, giving shine and health to the hair. To use FKS for a permanent conditioning service, the hair must be in reduced state (such as during a chemical service).
