There is really no way to fix your hair after it has been damaged by straighteners, dyes and perms, but you can take action to regrow a healthy mane and prevent further damage. According to the American Academy of Dermatology, people often misconceive that hair is living, but in reality, it does not heal itself once it is injured. Chemicals strip the hair of natural moisturizers that protect it and make it shiny. As a result, the hair breaks off or becomes dull, dry and frizzy.
Trim your hair at least 1/2 inch each month to slowly remove the damaged hair, as there is no way to truly restore your hair to its original condition.
Shampoo your hair just a few times a week with a creamy, sulfate-free hair cleanser. On the other days, you may opt not to wash your hair or use strictly conditioner.
Apply a protein-based, leave-in conditioner to your mane on a daily basis depending upon the level of dryness.
Apply a mask to your hair for 10 to 20 minutes once a week. Consider using warm olive oil or a mixture of egg whites and tepid water. Leave the mask on overnight with a shower cap for even deeper conditioning. Rinse with a sulfate-free shampoo.
Use a 50 percent synthetic and 50 percent boar bristle brush to gently push the oils from your scalp to the ends of your mane. Cut back on wearing intricate updos that put stress on your tresses. Whenever possible, limit the use of heated styling tools to a few times per week and allow your hair to air dry. If you must use heated tools, ensure the heat does not exceed 200 degrees Fahrenheit.
