Keramine H Strengthening Vials restore strength and beauty to weak, thin and easy to break hair. This product contains keratin and amino acids, which are essential hair components that perform an intense strengthening and repairing action. Keratin repairs the hair shaft, while amino acids strengthen the hair right from the root. Thanks to sericin, which is a silk derivative, WHITE Strengthening Vial protects hair from the drying action of the hairdryer, keeping it soft, supple and shiny. Ideal for normal hair, regular use of this product consolidates the hair structure while making hair easier to comb. It provides hold, lightness and a natural shine without greasing the scalp or weighing hair down. Perfect for those who want a high-level treatment that strengthens and regenerates the hair, keeping it healthy and shiny.
