_____________ perms give a soft natural curl pattern, are more gentle to the hair, gives more control due to slower processing time, and are better for fragile or chemically treated hair.

_____________ perms give a soft natural curl pattern, are more gentle to the hair, gives more control due to slower processing time, and are better for fragile or chemically treated hair.

• A. Acid perms
• B. Alkaline perms
• C. Exothermic perms
• D. Low/no Thio perms

Answer: (A)

Lower-pH acid perms use an acidic reducing solution, which keeps the hair from swelling too much and produces a softer, more natural curl. The acidic environment also slows the chemical reaction, giving you more time to monitor and control the curl formation, which is especially helpful when working with fragile or chemically treated hair. Because the processing is gentler and slower, it's less likely to cause additional damage and overprocessing. In contrast, perms with higher pH tend to soften hair more quickly and can be harsher on weakened hair, exothermic formulas rely on heat to speed things up, and low/no thioglycolate systems deliver milder results that don’t match the described gentle, naturally soft curl with strong on-hair control.
