E-Keratin Hair Clinic Shampoo by Eva Cosmetics is a premium, salon-quality hair care formula meticulously developed to rejuvenate, strengthen, and protect damaged, weak, or chemically treated hair. This advanced shampoo is enriched with hydrolyzed keratin an essential protein naturally found in hair that works to replenish and restore lost keratin caused by heat styling, coloring, environmental pollutants, and harsh treatments. The formulation is designed to deeply penetrate the hair fiber, where it repairs structural damage from within, helping to rebuild the integrity of each strand. By reinforcing the hair’s inner cortex and sealing the outer cuticle, the shampoo enhances hair resilience, making it noticeably stronger, smoother, and more elastic with every wash.
