While dry shampoo has major benefits—it can extend your blow-dry, soak up oil, and add texture to limp strands—it may also cause harm to your scalp and strands when overused. “For some, it can create irritation, or inflammation of the hair follicles,” Gohara says. “Most of the time, the scalp is un-fazed by dry shampoo, but when irritation does set in, it’s not fun.” So how much is too much? Gohara and Jones both recommend using dry shampoo no more than two days in a row. “My general rule of thumb is two times a week max for any leave-in product that doesn’t involve washing the hair, unless it’s a hydrating oil,” Gohara says. Here, a few other tips on the healthiest way to use dry shampoo.
