Various, Popular Science Monthly (1918)
“ Man has done much for woman, but he hasn't been able to make her hair grow in curly. Perhaps he will, by and by, who knows? In the meantime, your hair will grow, and if you want those curls to start in right at the root of your hair, you have to have the new hair curled once every six months. The long hair that was first curled will retain its curl to the end of time. ”
