Hello , I am a licensed cosmetologist and I need help! So I’ve permed my fiancé’s hair twice and the curls don’t come out curly! He has thick dark hair, I use white and grey rods and I use Feels so lovely regular hair solution. And I’m debating if switching over to the feel so lively resistant hair . It’s been 2 times that I’ve permed it and it’s not as curly! They come out like waves . Or they will be curly for a week and then gone!
