Need to brush up on your perm terminology? Here’s a quick guide to the lingo.

Root Perm: The root perm adds volume at the root of the hair to give lots of body. It’s also perfect for already permed hair that’s looking for a little pick-me-up. Because only the roots are treated, it saves the rest of the locks from another treatment.

Body Wave Perm: Creating big, bouncy curls, the body wave is for curl lovers who want a more modern look. Because this perm uses larger perm rods than traditional perms, the length of your client’s hair will determine how curly it will be: the shorter, the curlier.

Weave Perm: Because you’re curling only partial sections of the hair, the weave perm will give your client a fusion look with both textured and straight pieces in her hair.

Stack Perm: The stack perm is made for women who have a one-length cut. The treatment creates soft, layered curls for a natural look and is achieved by the use of differently sized rollers to the middle and bottom sections of the hair. The top is typically left fl at to look more natural.

Acid Perm: While it sounds harsh, the acid perm is actually gentler than the traditional alkaline perm as it has a lower pH level. It is specifically made for those with sensitive, fragile, or damaged hair.

Exothermic Perm: Referring to the gentle, internal heat that is characteristic of this treatment, the exothermic perm speeds up the processing time. The heat allows the lotion to absorb quickly into the hair, conditioning and strengthening the cuticle from the inside.
