Keramine H Strengthening Vials restore strength and beauty to greasy, weak, thin, and easy-to-break hair. This product is formulated with keratin and amino acids, which are essential components that perform an intense strengthening and repairing action. Keratin repairs the hair shaft, while amino acids strengthen the hair from the root. RED Strengthening Vial is specifically designed for oily hair, improving the hair hold, softness, and lightness without greasing the scalp or weighing down the hair. Regular use of these vials consolidate the hair structure and enhances its manageability, keeping hair strong and vibrant.
