Virtue Labs Recovery Shampoo works to repair damaged hair with each use. It gently dissolves daily build-up while filling in cracks of damage to leave all hair types, moisturized, soft, and supple. Formulated with our first-of-its-kind Alpha Keratin 60ku®, this shampoo behaves like a high-powered treatment product that deposits pure, human keratin protein directly into the hair. It fills in cracks in the cuticle to heal hair and repair damage from heat, chemicals, and color treatment. Color-safe, paraben-free, gluten-free.
