Which type of perm would process faster?

• A. Alkaline
• B. Acid
• C. Neutral
• D. Partial

Answer: (A)

Processing speed in a perm mainly depends on how quickly the reducing agent can break and rearrange the hair’s disulfide bonds, and how easily the solution can penetrate the cortex. Alkaline perms use a strong reducing agent in a high-pH formula, which lifts the cuticle and allows faster penetration and bond breakage. Because of that, the hair reshapes under the rod more quickly, shortening the processing time. In contrast, true acid perms rely on a lower pH and often require heat to speed the chemical reaction, making the process slower overall. Neutral perms sit in between in strength and speed, offering gentler action and longer processing times. Partial isn’t a chemical type of perm; it’s a technique for perming only certain sections, so it wouldn’t inherently determine processing speed the way the chemical type does.
