BC Bonacure Peptide Repair Rescue Deep Nourishing Micellar Shampoo is a repair-focused cleanser for chemically or mechanically damaged hair — over-processed color, bleach, heat styling, or worn, brittle ends. Its micellar base is built around hydrolyzed keratin and a keratin-derivative conditioning agent (steardimonium hydroxypropyl hydrolyzed keratin) that work to fill gaps along the damaged cuticle, with jojoba seed oil and panthenol added for extra softness. Schwarzkopf Professional describes the line's peptide-and-amino-acid complex as working to rebuild the hair's inner cortex and restore elasticity lost to repeated damage.
Apply to wet hair, work into a lather at the scalp and through the lengths, and rinse thoroughly; follow with a matching Peptide Repair Rescue conditioner or treatment for full benefit. Unlike the sulfate-free shampoos elsewhere in the Bonacure range, this formula contains sodium laureth sulfate and silicone conditioning agents (dimethicone, amodimethicone) for a richer, more cushioning cleanse geared toward coarse or heavily damaged textures rather than fine or color-sensitive hair.
