What is a depilatory?

A depilatory is a temporary hair removal substance that works by dissolving the protein structure of the hair, allowing it to be easily wiped away from the skin's surface. These products typically contain chemical agents such as calcium thioglycolate or potassium thioglycolate that break down keratin, the key protein in hair. This method is favored for its convenience and ability to deliver quick results, although the effects are not long-lasting compared to other hair removal techniques like waxing or laser treatments.

The other options refer to different aspects of cosmetology. Cutting hair is a direct technique used to shorten or shape hair but does not involve the removal of hair at the root, which is the primary function of depilatories. Hair coloring is a process used to change the color of hair and is unrelated to hair removal. A type of hair conditioner is used to maintain and improve the condition of hair but has no role in hair removal. Understanding these distinctions is crucial for effective practice in cosmetology, as each product and technique serves a different purpose in hair and skincare.
