Final answer:
An esthetician is trained in hair removal. Depilation, one common method, includes shaving or using chemical depilatories that break hair's structural bonds, allowing for easy removal.
Step-by-step explanation:
A person trained in the removal of superfluous hair is known as an esthetician or a cosmetologist specializing in hair removal techniques. When it comes to hair removal, there are two primary categories: depilation and epilation. Depilation involves the removal of hair at the skin's surface, while epilation removes the entire hair, including the part below the skin.
The most common form of depilation is shaving or trimming. Depilation can also be achieved through chemical means, such as the use of chemical depilatories. These chemicals typically work by breaking down the disulfide bonds in keratin, which is a protein that gives hair its structure and strength, making the hair easy to wipe away from the skin's surface.
