Once hair has been washed and conditioned to max out volume, the next step to prepping fine hair for long-lasting oomph is to apply the correct styling product — and the right amount of it. "Towel-dry hair to damp and apply ARROJO Volume Foam from roots to ends. The amino acids in the product help to plump, thicken, and lift the hair shaft. Meanwhile, because the product is a foam, it makes it easier to apply where volume is created: at the roots."

While it's common for fine-haired girls to fear product overload, Arrojo actually insists that when you're using the right product for your hair type, more is actually, well, more. "Product usage follows a simple rule of thumb: the more you want to volumize, the more product you should use. If you left your hair unwashed for a day or two afterwards, then product build-up can be a problem, so the trick is to know when to shampoo and condition your hair clean of product. For example, you may use a lot of product to give your hair the wow factor for a big night out –– in that case, you know you’ll need to shampoo and condition the next day." If you follow this rule, you'll ensure that you don't over-wash hair, which can majorly dry out your locks.
