E-Keratin Intensive Hair Nourishment Ampoules by Eva Cosmetics are a specialized hair treatment designed to combat hair loss and enhance overall hair health. Each 7ml ampoule is infused with a potent blend of keratin, vitamins, and essential nutrients that penetrate deep into the hair shaft to repair damage and promote healthy hair growth. The unique dual-action formula works by forming a protective film over the hair, shielding it from environmental aggressors, while simultaneously strengthening the hair from within.
