I love perms on long hair.
In the 80s I had a chopstick perm which cost £225 which at the time was very expensive but the result was amazing and it lasted well.
My other perms wee of the big shaggy types and they didn't look so good as they grew out and as another poster said, the initial look was very tight and you had to wait for it to relax before it looked good.
I had one horrendous experience where my regular hairdresser got a call about her mother going to hospital and she was about to start my perm and a junior took over.
She left the top and front on too long and took the rollers out of the back too soon.
It looked ok when I left but a week later the back was almost straight and the the sides were very curled! 😩
