Daily grooming practices like washing, brushing and styling can cause damage to your hair and leave it looking frizzy, broken and dry.

To understand why this happens, you need to know more about your hair’s structure. Your hair is made up of three layers:

 

  • The medulla:This is the soft, central part of the hair shaft. Interestingly, thick hair contains large amounts of medulla, while fine hair has almost none.
  • The cortex:This is the thickest layer of your hair. It contains lots of fibrous proteins and the pigment that gives your hair its color.
  • The cuticle:The cuticle is the tough, protective outer layer of your hair.

Washing, styling and coloring your hair can damage the cuticle, rendering it unable to protect the central parts of the hair shaft.

This causes you to lose some of the fibrous proteins that make up your hair’s cortex, making your hair thin, fragile and prone to breakage.
