Lorraine Massey, co-owner of Devashan Salons, co-creator of DevaCurl hair-care products, and leader of the “pro-curl revolution,” is having a book signing and demonstration Thursday, April 28, at Pink on Palmer in Larchmont (link here) from 6 to 8 pm. In her new book, Curly Girl: The Handbook, Massey advises readers to toss out their regular shampoos along with blow-dryers, flat irons, brushes, and hot combs, and replace them with a good sulfate-free cleanser, a botanical conditioner, and hair gel. Striving to reduce curly girls’ dependency on harsh products and styling tools, Massey offers cleansing and styling routines for each curly and wavy hair type—Corkscrew, Botticelli, Corkicelli, Cherub, Wavy, S’wavy, Fractal, and Zigzag curls. Ladies: liberate your curls!
