Unfortunately no matter how many DIY hair treatments, hair masques or serums you use there aren't ways to repair the damage. These treatments and products can sometimes help to temporarily cover up the damage to your hair. They may even help to prevent future damage, but products and treatments can't repair or fix hair when it's damaged. The best thing to do when your hair is damaged is let it grow out while using healthy hair practices so your new hair doesn't get damaged.
- The outer layer called the cuticle
- The inside layer called the cortex
- The center layer called the medula
The cuticle, the outer layer, is made up of flat scale-like cells of protein and is the first defense for the hair against heat styling, chemicals, manipulation, etc. When the cuticle is damaged, the scale-like cells tend to stay raised up and don't flatten. This leads constant loss of moisture in the hair and constant dryness.
The raised cuticle cells also allow the middle/inside layer of the cortex to be damaged. The cortex is the part of the hair that dictates the strands thickness, color, curl pattern, and other attributes. Damage to the cortex can't be undone.
There are many things that can damage the cuticle. Here are the four most common:
1) Direct heat from heat styling tools. By applying heat directly to the hair it cracks the hair cuticle and withdraws moisture.

2) Chemical treatments from the misuse of relaxers, perms, bleaching, and coloring. The chemicals in these treatments break and wear down the hairs natural protein bonds weakening the hair strands. Constant misuse, such as overlapping treatments, can have very damaging effects to the hair

3) Friction which comes from excessive styling, combing, or even unprotected hair rubbing against a cotton pillow. This constant rubbing movement of the hair strands is what causes the damage.

4) The elements such as the sun and wind. The sun can dry out the hair and the wind causes friction and tangles.
