If you are a woman of color, you should never wash your hair every day. Ethnic hair is dryer than other hair types and dries out easier. It will also keep natural oils in your hair that it needs to grow and not break off. Washing your hair just 2-3 times a week is recommended. Use oil on your scalp after shampooing. You should always do this when your hair and scalp is clean. Apply the oil directly after shampooing and make sure you evenly distribute the oil through your scalp to avoid any build-up you might have and that the oil might cause.
When you are drying off your hair after a shower, do take care to be quite gentle. Vigorous and enthusiastic rubbing can cause hair damage and breakage to occur, not to mention, tough to remove tangles. Instead, take the towel and gently squeeze out the excess water, while delicately blotting the roots.
If you are going to a spa, the one thing that you will want to try to avoid is a steam room or sauna. The excess heat can dry your scalp, which can cause dandruff and an uncomfortable feeling during the day. Avoid heat if you desire to maintain healthy, comfortable hair.
