As you strip oils from your hair, your skin begins overproducing it to compensate. Every other day is a good schedule for most people to wash hair. Give hair a protein-based deep conditioning treatment once a week to help repair breakage from ponytail styles and the baking sun. Go easy on those because they can change your hair's texture for the worse. Try alternating with a hydrating mask for hair and allow it to sit on hair for 30 minutes, wrapped in a warm, damp towel to retain and enhance the treatment. And get to the stylist to get dry, split ends cut off and to add a fresh application of color. You may decide to get all the unhealthiness chopped right off and start new.
