The optimum use rate may vary depending on the condition of your hair. Make sure not to exceed the maximum concentration of up to 3%, because if you use too much, your hair can become stiff or look greasy.

Naturally, keratin is produced by cells called keratinocytes, and just as collagen or elastin, this protein helps keep the skin firm and forms a protective layer to retain healthy skin. This barrier helps keep out pathogens and helps minimize serious damage from other environmental factors. Because keratin is a natural structural component of the skin, when it is replenished, it helps fortify the skin to make the structure stronger and less prone to sagging skin. The skin tightening properties of a keratin treatment make it a potent anti aging product that can help get rid of wrinkles and reduce the appearance of sagging skin.
NOTE : Keratin can be added to your deep conditioner and left in your hair under a shower cap for about an hour. A thorough rinse is necessary once done and a moisturizing conditioner can be added as a complementary agent.
