Nothing strips hair faster than a frothy lather, says Fabian Lliguin of Cocoon Hair Studio in N.Y.C. When your scalp is dry, it produces more oil to compensate, resulting in greasy roots and brittle ends. “It’s a catch-22,” says Lliguin. Instead, apply a conventional shampoo only to the scalp or switch to a gentler oil-based shampoo.
