Olive oil works great on your hair, relaxes the curls and improves the appearance of your locks. Take a cup of olive oil, heat it (don't make it too hot). Now comb your hair and start applying olive oil to the scalp and entire length of hair. After finishing, wrap your hair in a shower cap or towel. Using a blow dryer, heat this towel from all sides for about 10 minutes. Leave for an hour, shampoo and condition as usual. You can add a hair conditioner to the olive oil while boiling it.
