Hi, I want to take my mom to a salon to update her hair. Her hair is a bit of a mess. It's dry and overprocessed. She has a perm but it's frizzy. She doesn't want her hair cut short. Right now it's slightly above her shoulders (it may be longer but because of the perm that's the length it looks like to me). I can't really determine what her cut looks like because of the perm. What do you think is the most thing she should do? Is a blow out a good idea, given the condition of her hair and her perm? What would a deep conditioning treatment do to the look of her hair? Would it make her hair look more flat? (She wants volume in her hair.) Thank you so much. This whole thing perplexes me!
