As the time goes by, keratin gets weaker in the hair structure and the hair become frizzy and fragile.

In addition to making the hair silky, bright and smooth, the keratin-added BioMagic Hair Color Cream strengthens the hair against sunlight, wind or extreme heat changes and the external chemicals such as UVA.
