Permanent Waves Process & Heat
Q: Is there a difference between a permanent wave processed with heat vs. a permanent wave processed without heat? Is one
better than the other? What do you recommend?
A: Permanent waves that require heat to process are known as endothermic waves and are generally going to be your ‘true acid waves’
and ‘low-pH waves’. These permanent wave types are used for people who have very fine-textured, very porous, or damaged hair that
needs very special care. They tend to be slow to react and gentler for these hair types.
The waves that don’t use heat for processing are either exothermic waves (which produce their
own heat through chemical reactions) or ‘cold waves’ which process at room temperature. The exothermic waves are best used for those
whose hair is hard to curl or thick and coarse, while the cold waves are best for those with “normal” hair.
The type of wave you choose is going to depend on the type of hair you have. Just remember that the
hair should always be in good condition before perming, regardless of your hair type. If your hair is damaged, it would be advisable
to see a professional for any chemical services, since you are risking hair loss if you should make a mistake.
And always, ALWAYS remember that you are using chemical processes on your hair regardless of
how gentle or “easy” the product claims to be. Pay close attention to timing and processing the hair.
