The characteristics of healthy hair, such as shine, softness and body are those most associated with virgin hair. Virgin hair is hair that is untreated; it hasn’t been chemically-processed, either with chemical straighteners, such as relaxers, nor has it been color-treated. These processes mentioned take place at extreme pH’s, and the exposure to high pH causes the cuticle to swell so the process can take place, but in doing so, it causes cracking and damage to the cuticle (the hair’s protective outer layer) and to the cortex (the hair’s inner layer). Chemical processes aside, hair is also subject to damage by environmental factors, such as exposure to UV light and by styling, including exposure to excessive heat, as in flat iron use, or by tight braiding. All of these factors can by themselves, and then cumulatively too, cause the hair fiber to degrade, weaken, stretch, to lose elasticity and to ultimately fail or break. These same factors impact the health and integrity of the scalp and follicle, the source of healthy hair growth.
Damaged hair fiber can be protected and it can be both nourished and repaired. Keranique Scalp Replenishing Shampoo is a nutrient-rich, sulfate-free, paraben-free formula which gently cleanses the hair and scalp. It is non-stripping and moisturizing. Infused with Keratin Amino Complex it protects both the cuticle and the fiber core. It helps prevent future damage. It imparts strength, repairs split ends, smooths the cuticle and improves fiber quality.
