How to fix heat damaged hair?

Prevent Further Damage : It is important to prevent further damage when it comes to repairing damaged hair. To do so, first you should avoid suing heat tools. If you can’t avoid heat tools, try keeping the frequency of use to a minimum and always use heat protection.

Use protein-based conditioner : Protein-based conditioners fill the tiny rips and tears in your hair, & makes it stronger. The repair is not permanent, and only lasts until the next time you wash your hair. The benefit is that your hair is stronger and more resistant to damage.

Replenish your hair with a hot oil treatment : Heat some olive oil over the stove, then allow it to cool down to room temperature. Apply it to clean, towel-dried hair. Tuck your hair under a shower cap, then wrap a hot towel around your hair. Wait 1 hour, then rinse the oil out with cold water. For a deep conditioning treatment, leave the oil on overnight. Use shampoo to remove any residue, if desired.

Cut the damage off : Cutting the heat damaged ends is highly recommendable. How short you cut your hair depends on how far up the damage extends. Ideally, you should cut all of the damage off. If your hair is damaged all the way to the roots and you don’t want to cut all of your hair off, cut layers into it instead. This will prevent the damage from creeping further up the hair shaft. If you don’t want to go too short, you can trim your hair every 4–6 weeks until the damage is gone.
