3. Boost Shine

"Dull, overstyled hair benefits from regular olive- or jojoba-oil masks," explains Goddard-Clark. Starting at the roots, brush a quarter cup of natural oil (synthetic oils don't work as well) through dry hair and leave it on for an hour. Blast the ends with a dryer for five minutes to help oil penetrate deeper. Skip the roots — the scalp emits enough warmth on its own, and applying extra heat could lead to greasy textures later.

MC Tip: Cut washing time and add shampoo to strands before they get wet to dissolve the oil faster.
