What it is
Formulated with a highly restorative, high-concentration hematin, simply spray onto your hair during shampooing to instantly repair cuticles. This treatment conditions the cuticles, which determine shine and texture, resulting in naturally firm, supple, and beautiful hair. Hair damage is the cause of quick color, perm, and gray dye fade. Hair Repair Serum's high restorative power repairs cuticles, eliminating the damage caused by color and perms, resulting in shiny, color-perfect hair. Hair Repair Serum also addresses the root causes of hair problems, such as lack of firmness and volume. Aloe vera leaf extract and Melia azadirachta leaf extract care for the scalp, which is stressed by perms and hair color, and promote a healthy scalp environment. Hematin has been a valued ingredient in salons for 30 years for its hair repair properties. Its protein-binding properties allow it to quickly bond with keratin, the main protein component of hair, instantly repairing damaged hair. Hematin treats damaged, coarse hair and smooths the cuticle, leaving it feeling soft and shiny immediately. With continued daily use, you can continue to achieve healthy, black hair.
