After a few months of sun, sand and chlorine, your hair is probably ready for a much-needed rest. Summer takes a toll on hair, drying it out, sapping it of color and making it frizzy and unhealthy. Now that you've put all that summer fun behind you, it's time for an intervention. Start by giving your hair what it wants - moisture. Switch to a hydrating shampoo and conditioner (be sure to use a separate conditioner, not a 2-in-1 formula, so you get plenty of hydration). Seal in moisture with an anti-humectant styling cream, like Frederic Fekkai's. Smooth it through hair to seal in moisture. Humidity saps your hair of moisture, so it helps to replenish it on a daily basis. Go easy on shampoos so that your scalp doesn't dry out.

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.
