Final answer:
Chemical depilatories remove hair by decomposing the papilla, breaking disulfide bonds in keratin and hydrolyzing the hair for easy removal.
Step-by-step explanation:
The hair removal method that removes hair by decomposing the papilla is chemical depilatories. Chemical depilatories contain active ingredients such as salts of thioglycolic acid and thiolactic acids, which break the disulfide bonds in keratin and hydrolyze the hair, making it easy to remove. However, it's important to note that depilation using chemical depilatories does not destroy the dermal papilla, so the hair will eventually grow back.
