If your hair is thin and straight, after taking a shower and patting your hair dry with a towel, reach for a spray leave-in conditioner. "Spritz it on the ends of your strands and use a comb to distribute it through the strands — if your hair is fine and you apply product directly to the roots first, it’s going to look greasy," says Nicole.
Looking to give your hair volume and wave? Once your hair is totally air-dried, a texture spray will do the trick. "Get to work or wherever you're going, shake your head upside down, spritz texture spray at the roots, and that's it," Nicole adds.
