The relationship between keratin protein and disulfide bonds

Our hair is made up of the protein keratin, which gives it strength and elasticity. Disulfide bonds are responsible for the structural stability of the hair fiber, but are weakened by chemical treatments, heat, and daily wear and tear.
The PROHAIR + keratin series restores the hair's internal strength, restores disulfide bonds and gives it a healthy, strong and flexible appearance over time.
