Lazartigue Smart Repair Concentrate is an intensive repairing treatment designed for damaged, sensitized, bleached, or weakened hair. Its main function is to act on the hair fiber to help restore strength and improve the appearance of the most damaged areas, especially the lengths and ends. The formula uses 3-Plex Technology, a combination of active ingredients that acts at different levels of the hair fiber. The combination of itaconic acid and arginine helps create new bonds between keratin chains; peptides and vitamins contribute to restoring damaged keratin chains; and polysaccharides from chia and flax seeds help improve the appearance and manageability of the hair. The formula also contains panthenol, soybean oil, flaxseed extract, chia seed extract, oat peptides, biotin, and tocopherol, ingredients that contribute to the conditioning, hydration, and cosmetic protection of the hair fiber. The texture is light and non-greasy, allowing the product to be applied to the lengths and ends without rinsing. It is particularly recommended to complement a repair routine when hair is weakened by coloring, bleaching, heat or other aggressions.
