Final answer:
Sugaring is a method of hair removal that applies a sugar-based paste with hair growth and removes against it. However, chemical depilatories use active ingredients like thioglycolic acid to break down hair for removal and come in various forms.
Step-by-step explanation:
The method of sugaring which involves applying the product with the hair growth (similar to soft wax) and removing it against the hair growth is a form of hair removal technique. Sugaring is a technique that can be used to remove hair, which uses a sticky, sugar-based paste. Some people find it less irritating and a natural alternative to waxing. However, the question seems to be referring to the use of a chemical depilatory, which is a cosmetic preparation used to remove hair from the skin.
Common active ingredients in chemical depilatories include salts of thioglycolic acid and thiolactic acids, which break the disulfide bonds in keratin, making the hair easy to remove. These depilatories usually come in the form of gels, creams, lotions, aerosols, roll-ons, or powders and require careful application following their instructions.
