These days, just about everyone is doing something to their hair. Coloring it, adding highlights, straightening or curling it… even a blow dryer and hair brush will damage hair over time. Hair can only take so much, and it can’t repair itself. Understanding damaged hair: The hair shaft is made up of dead, hard protein called keratin, in three layers. The inner layer is called the medulla. The next layer is the cortex, and the outer layer is the cuticle. The cortex makes up the majority of the hair shaft. The cuticle is formed by tightly packed scales in an overlapping structure, similar to roof shingles. When hair is damaged by chemicals, heat or trauma such as brushing through tangles, pieces of the cuticle chip off and expose the delicate cortex. Without its cuticle as protection, hair kinks (frizz) and is weak and breaks easily. When this happens near the bottom of the shaft, the layers of the exposed inner cortex start to peel and fray (split ends). The tear will travel up the shaft and eventually the shaft breaks. This is why it can be almost impossible for some people to grow their hair long. It just keeps breaking! To repair the damage, you need to replace the missing keratin protein. Our collagen treatment is a unique product, and is the only one of its kind on the market that is just pure protein, nothing else. It has a low molecular weight so that it can work its way down to the cortex and protect the hair shaft from breakage by replacing the hairs lost protective cuticle. Unlike the Brazilian and other salon keratin straightening treatments, there is no long process of drying and straightening and then letting it cure for days after a treatment.
