The 5 Biggest Hair Myths, Busted

More Myths

A cool-water rinse is a common last step during a salon shampoo to make the hair shinier. While it may reduce some frizz by sealing the cuticle, the real value of the cool rinse is actually to the scalp. Like the pores on your face, cleansing with warm water opens up the hair follicles, which allows your scalp to release oil and toxins. A quick shot of cool water helps seal them up again to keep your scalp balanced.

Many women believe that they have straight hair with just a few dysfunctional pieces called "cowlicks." But usually you'll find those pieces aren't misbehaving after all -- hair can simply have varied textures throughout. Even women with straight, fine hair can have some curl hiding within. If you have hair like this, a layered cut is a great way to help mix different textures and encourage hair to spring up instead of lying flat -- which makes textured areas stand out instead of blending in.
