Having dry, damaged hair issues a great product to try is Kerastase Noctogenist Serum Nuit ($65.00). This easy to use overnight hair treatment is designed to absorb into the hair, giving you softer, more manageable hair all while you get in a few zzzz. For added tress protection, switch from your cotton pillow case to a satin one. It will keep your hair from getting tangled at night.
If the Kerastase is way beyond your beauty budget then try John Frieda Frizz-Ease Crème Serum Overnight Repair Formula ($9.99, drugstores).
