Which hair removal method can be done using sugar paste?

Sugaring is the correct choice because it specifically involves the use of a sugar paste to remove hair. This method utilizes a sticky mixture made from sugar, water, and lemon juice, which is applied to the skin in the opposite direction of hair growth and then removed in the direction of hair growth. This technique not only helps in effectively removing hair but can also result in less irritation compared to other methods, such as waxing.

Other methods listed, like threading, waxing, and shaving, do not involve sugar paste. Threading uses a thin thread to physically pluck hairs from the follicle, while waxing involves a sticky substance made from resins, wax, and sometimes sugar, but typically refers to a different process than sugaring. Shaving, on the other hand, involves cutting hair at the skin's surface using a razor and does not remove hair from the follicle at all. Therefore, sugaring is distinctly recognized for its use of sugar paste.
