The more hair you have, the more product you need, right? Yes -- sometimes. If you have thick, wavy or otherwise unruly long hair, you probably need to be liberal with the styling products. But everyone else should ease up -- it's also true that the more hair you have, the more weighed-down and limp it can get. If your long hair is fine or straight, you should avoid your roots when applying conditioner or any other hair products. Your roots will end up lighter and bouncier when the product is concentrated where you need it most -- at those damage-prone ends.
