Frequently Asked Questions
Functional keratin in Tressa Tools FKS Serum is a hydrolyzed protein that penetrates the hair shaft to strengthen and repair damaged areas. Unlike cosmetic keratin that sits on the surface, functional keratin works to restore structural integrity from within, helping reduce breakage, frizz, and split ends while improving overall hair resilience.
Yes, Tressa Tools FKS Serum is formulated to be safe for color-treated, chemically processed, and damaged hair. The functional keratin complex actually helps protect and restore chemically compromised strands. However, if you have a known sensitivity to any listed ingredients, perform a patch test before full application.
Tressa Tools FKS Serum works best on clean, damp hair before styling. Apply to mid-lengths and ends, then style as usual. For intensive treatment, you can also apply to dry hair for a quick moisture and shine boost. Avoid applying directly to the scalp unless you have very oily roots.
