Repair Summer-Damaged Hair
6. Look for signs of serious dehydration. "If your hair won't hold a style no matter what you do to it, it's very dehydrated from the summer," says Villa. To remedy, avoid drying styling products such as gels containing alcohol, and maximum-hold hairsprays.
7. Step up the hair nourishment in your diet. According to Villa, good fats, such as omega-3s, and B vitamins actually help hair grow strong, shiny, and full of body. Try adding salmon, tuna, nuts, and seeds to your diet (just a small serving a day should do it).
8. Use cool air to dry. The heat from your blowdryer will damage hair just as the sun does. While you're nursing your hair back to health, switch to the cool setting.
9. Lay off the hot tools. Heated metal styling tools, such as flat irons and curling irons, can make summer damage even worse. The good news is that textured styles are back in vogue, says Villa, so you can safely give your tools a rest and still look chic for the fall.
10. Try a salon treatment. While at-home hair masks can be somewhat healing, a professional moisturizing treatment can repair damaged locks and impart shine more effectively. What's more, they're quick and relatively inexpensive.
