KEVIN.MURPHY THICK.AGAIN is a leave-in thickening treatment to fortify hair and prevent breakage. With a complex of thickening ingredients, scalp microcirculation is improved and hair loss is reduced.
The key thickening ingredient in KEVIN.MURPHY THICK.AGAIN is Biotinoyl Tripeptide-1. Derived from the technology used in eyelash thickening and lengthening products, this peptide repairs and strengthens hair by helping to close split ends and swelling the hair shaft for the impression of thicker hair. Amino acids add softness and shine to the hair by penetrating the strands for deep conditioning from within.
