The Pro-Geno Cuticle Sealer is a finisher designed to close the hair cuticle, correcting imperfections and restoring the integrity of the hair fiber. Its principal function is to seal the layers of the hair strand, getting rid of porosity and preserving essential nutrients. More than just taming and smoothing the hair, it reduces friction when combing, delivering more softness and natural movement. Its thermoactivated action forms a protective shield against heat from dryers and irons preventing heat damage and strengthening the strands.
