Healthy hair starts with a healthy scalp, and Carol's Daughter Fortifying Scalp Spray ($22) will help you achieve both. The special applicator tip enables you get the product to where you need it most. Just part your hair, spray on the herbal-citrus-scented treatment, and rub it in before you shampoo. Aloe and cedar leaf work to soothe itchy, inflamed skin, while camphor oil lends a tingling cooling effect. If flakes and dry patches are a concern, there's even sugar cane extract to help lightly exfoliate. Now you can wear your LBD and dance under black lights without worrying your flakes will be revealed.
