RINSE
Over-washing is the most common hair mistake people make, and it can dry out locks and fade color. The best thing you can do is wash your hair every other day. If your hair is oily, try a dry shampoo.
COLOR
Never do a drastic color shade makeovers at home, leave to the pros. If your going to do your own color, stay within two shades of your current color. Especially if you're going lighter.
