Liquid Perm and Foam PermQ: What is the difference between a perm with the standard type of waving lotion and a perm with a foam type waving lotion? I am a male who receives home perms from a family member mostly due to the comfort factor of not having to be in a salon. She uses quite small rods and my hair ends up curly but not too tight.
Home perms are becoming harder to find thus resulting in the purchase of a foam perm. Is a foam perm stronger? I don't want to end up with an "afro" but I don't know how you would check the curl during processing without rinsing the foam off? Is there a trick to this? Thanks for your help in advance.
A: The only real difference between the more typical “liquid” waving lotion and the “foam” waving lotions in a permanent wave kit is that the solution for breaking the chemical side bonds and rearranging the wave pattern of the hair is formulated into a different state. In other words, it’s nothing more dramatic than the fact that one is in foam form. The reason for creating the waving lotion as foam is that the foam formula doesn’t drip as much and clings to the wrapped hair as it soaks into the hair shaft.
Foam formula perms come in as many different formulations as do liquid formula perms. How well they work and the types of curl produced are determined by the size of the rods, the length of processing time and skill of the operator at wrapping the hair and determining the progress.
You should be safe from the “afro” look as long as you use the same size perm rods as you always have. As with any product (whether or not you have used it before) read the packaging instructions carefully and perform both a patch test (top make sure you don’t have an allergic reaction) and a test curl/strand test (where you wrap and process a single curl in order to see how the hair responds to the formula and the results thereof).
And as for checking the curl during the curling process you simply unwrap a curl at random on the head partially – holding it loosely – and look for the classic uniform “s” wave in the hair as it is slowly unwound from the rod. The more pronounced the “s” is the firmer the curls are likely to be.
