What is the main purpose of chemical depilatories?

• A. Remove hair permanently
• B. Dissolve hair at skin level
• C. Remove hair from the root
• D. Lighten hair color

Answer: (B)

Chemical depilatories are designed to dissolve hair at the skin surface, so it can be wiped away without pulling from the root. They use reducing agents (like thioglycolates) that break the disulfide bonds in keratin, softening and dissolving the hair shaft right at or near the skin. Because the hair follicle beneath the skin isn’t removed, the effect is temporary and regrowth occurs from the root. This distinguishes them from methods that remove hair from the root, such as waxing or tweezing, and from permanent methods like laser or electrolysis. They don’t lighten hair color—that’s a different process. For safe use, follow the instructions, perform a patch test, and avoid applying to broken or irritated skin.
