It's not called beauty sleep for nothing. A lot happens in the wee hours you are in la la land. Damaged cells are repaired and your immune system and brain power is revitalized, not to mention, your hair! What is your night-time regimen? If you don't have one, maybe it's time to start!
2) After towel drying your hair apply a leave-in to renew tired, dull looking hair and then loosely twist and wrap in a low bun. We love Kerastase's Noctogenist line and it smells fabulous! This leave-in may make hair feel "greasy" when you put it on, but surprisingly disappears by morning!
3) Finally, replace cotton pillow cases with satin or silk. Cotton creates friction that ruffles the cuticle and makes hair frizzy which also helps prevent less breakage and split ends.
