My girlfriend has naturally curly hair when she gets out of the shower. She wanted to get a perm that would be just like her naturally curly hair all of the time.

She just got the perm today and she says the curls are way too tight. I know it falls down a bit after a few days, but she says it is much tighter than it was right after the last time she got a perm.

What can she do to loosen the curls?

What shampoo and conditioner should she buy?
