The Inkey List Peptide Volumising Hair Treatment gives an instant shot of volume to flat, lifeless tresses. Ideal for all but best used on thin hair types, this hair serum is designed to invigorate limp locks from root to tip. Powered by an intricate blend of Peptides, the lightweight formula charges every strand with its revitalising properties. These peptides, which are chains of amino acids that reinforce proteins naturally found in our hair, strive to stimulate the growth of stronger, healthy-looking locks. 2% Keranutri™ and 2% ACB Pisum Sativum Peptide work in perfect harmony, plumping the cortex directly to help boost the diameter of thinner strands. Betain combats dry hair, wrapping your mane in its moisturising benefits. This volumising hair serum creates enviable shape and shine while ensuring lengths remain conditioned.
