Hair can become dry and tangled for a variety of reasons. Over-processing hair with frequent chemical treatments or coloration can damage hair. Using high heat styling products like hair driers can also cause hair to become very damaged. Hair products, although useful, can strip hair of its natural oils. Using too much shampoo without following with conditioner can leave your hair dry and tangled. Restoring dry, tangled hair is simple and can take less than one week.

Shampoo your hair once during the week in which you are concentrating on repairing damage, instead of every day. Shampoo strips your hair of natural oils, contributing to dryness and making the tangling worse. If your hair becomes overly oily during the week because you're not shampooing as often, apply a dry shampoo to the roots to absorb the oil.

After shampooing your hair, rinse the shampoo out. Apply a deep conditioner and leave it in your hair for 10 minutes, or as long as instructed on the bottle. Rinse your hair of conditioner thoroughly and towel dry by squeezing sections of your hair gently with the towel. Do not use a blow dryer, and do not rub your head with the towel.

Comb the tangles out of your hair gently with a wide tooth comb, while your hair is almost dry. Start at the bottom of your hair and work up toward the roots. Doing this the day you use a deep conditioner will make the tangles come out easily.

Pour a handful of coconut oil into your hand. Work the oil through damp hair with your fingers. Pile your hair on top of your head and wrap it with plastic wrap. Leave the oil in overnight. The heat from your body and the plastic wrap will help your hair absorb the oil. The next morning, rinse it out with warm water and comb your hair with a wide tooth comb once more. Do this once a week.

Repeat this week of damage repairing steps whenever you feel like your hair is becoming frizzy again. This will be more frequently for some people because of repeated hair coloring treatments or use of high heat styling products. If you can't tell whether your hair is damaged or not, ask your hair stylist.
