If your hair is super fine, you're probably looking for a shampoo that can deliver some serious, runway-worthy volume. That's why Bova always reaches for Jason Thin-To-Thick Extra Volume Shampoo, $9.25, when styling his fine-haired clients. "Hair-strengthening biotin and panthenol wrap around the entire hair shaft to boost volume and increase hair cortex elasticity for less breakage," he says. "Natural plant proteins add luster and bounce so that your hair looks and feels naturally thicker with a healthy dose of shine."

If you frequently deal with an itchy, irritated scalp that has tons of dandruff, you'll find a saving grace (and serious relief) from all-natural products that are free from artificial fragrances and other irritants like parabens, sulfates and formaldehyde, like Cleure Volumizing Hypoallergenic Shampoo, $12. "It's safe for all skin types and all hair types, as well as color-treated hair, and is cruelty-free," says Bova.

If you're looking for something more powerful to help treat and improve your scalp and keep hair healthy, try Vitabrid C12 Scalp Shampoo, $32, which is packed with safe and effective ingredients such as antioxidant vitamins including zinc oxide, dexpanthenol, menthol and salicylic acid, to strengthen the hair while hydrating and soothing the scalp.
