Donda, Thanks for your reply.
I don't know what hair type my mom has. Maybe a 2 something. Anyway, she does a wet set when she washes her hair every week. Well, the curls flatten overnight and so every morning she greases, combs out her hair, then kind of recreates the curls from the rollers with the curling iron. I don't know if I explained that correctly.
She never lets any type of moisture get near her hair though. I wonder if it would work for her?
