Various factors cause hair damage – recurrent use of styling products, heating tools, bad eating habits, chemical treatments, and environmental aggressors. Thankfully, you can repair damaged hair if you take care of your hair. Scroll down to learn about the causes and types of hair damage and how to treat it. Swipe up!

What Exactly Is Damaged Hair?

Damaged hair is when the outer hair cuticles are lifted to expose the hair cortex (the inner layer), affecting the hair’s structural integrity.

The hair shaft has three layers: medulla (the innermost part), cortex (the second layer that contains keratin fibers and melanin), and cuticle (the outer layer composed of dead, overlapping cells).

In healthy hair, the cuticles are flat, sealing moisture and protecting the inner layers to keep the hair shiny and smooth. Excessive chemical and color treatments, harsh products and grooming methods, exposure to UV rays, and pollution separate the cuticles, changing the hair texture. As a result, the hair looks frizzy, unmanageable, and damaged and becomes breakage-prone.
