Hair Thickening Serum

Peptides are chains of amino acids that support proteins naturally found in hair. Limp and thin hair is an incredibly common hair concern across all hair types and lack of volume can be caused by a number of things, including diet, product build up, hormones, genetics or stress.

This lightweight serum, has been formulated with two  peptides (2% Keranutri™ and 2% ACB Pisum Sativum Peptide) to work in the hair cuticle to plump the cortex and increase the diameter of each hair strand. We have added Betaine to the formualtion to also help condition hair.

The result? A significant hair volume increase through the appearance of 10,000 more hairs after just one use and soft and healthy hair.
