Hair damage is more than just split ends. Extremely damaged hair develops cracks in the outside layer (cuticle). Once the cuticle lifts (opens), your hair is at risk for further damage and breakage. It may also look dull or frizzy and be difficult to manage. So can you really go from dry, brittle hair to smooth, shiny locks? The answer isn’t always cut and dried. For the most part, hair damage is permanent because hair is actually a collection of dead cells, making them beyond repair. The only real cure is time, a pair of shears, and taking steps to prevent new damage. But don’t despair, with proper hair care and a few targeted treatments, you can help restore the outer cuticle and begin to improve the look and feel of your hair.
