Can a 5-minute perm water perm a man's hair?
I can't. Perm potion, also known as thermoplastic perm, takes a certain amount of time and heating to set the curly hair, so as to get the desired curly hair effect. If it is only 5 minutes, it is not enough to completely perm men's hair. Ironing lotion usually needs heating, so that hair can better absorb the chemicals in lotion, thus changing the shape and texture of hair.
