Tri-Lash Pro™ is a multi-peptide solution that promotes thicker, longer eyelashes. Tri-Lash Pro™ consists of four peptides that, together, 1) stimulate keratin production for stronger, thicker lashes, 2) promote the synthesis of key adhesion proteins that help fix hair in the follicle and reduce shedding and 3) promote eyelash growth through extension of the anagen (growth) phase.
