Start with completely dry hair and brush it all forward. Do not make a part. To get a beautifully wavy texture, wind your hair around a half-inch barrel curling iron (wrap every section of hair that’s longer than one inch). Start halfway down the hair shaft and go all the way to the ends. “Don’t be afraid if it looks like a bunch of curly-Qs at first," says Brill. "You want the hair to be really defined before you mess with it."
