Lorraine Massey, author of “Curly Girl: The Handbook,” will speak at noon Tuesday at Madusalon, 300 Divisadero St., S.F.; at 7 p.m. Tuesday at A Great Good Place for Books in Oakland; and at noon Wednesday at Peninsula Beauty in Burlingame.

Being at the forefront of the “pro-curl revolution,” can you briefly describe what you advocate? All it is, really, is cleansing hair properly and letting it dry naturally.

What are women with curly hair doing wrong? They’re assaulting their hair with synthetic materials, and they’re killing it by “blow-frying” it. ... What they have naturally will be more beautiful if it’s treated with care by using “no poo” methods.

What do you mean by “no poo methods”? Instead of using shampoo, use only 100 percent sulfate-free conditioners. Conditioner is my be-all and end-all. It’s like drinking carrot juice instead of soda.

Who is your audience? Sixty-five percent of the women on the planet, of all ethnicities, have curly hair. They should know that frizz is a curl waiting to happen.
