What is happening:

Since hair is not a living tissue, it cannot be repaired once it’s damaged. Color-treating hair, using sulfate-based shampoos, wet brushing, heat styling, and the environment can harm the hair’s protective outer cuticle, leaving the inner layers (including the cortex) more vulnerable to damage.
