What is the process of breaking contact between the bulb and the dermal papilla called?

The process of breaking contact between the bulb and the dermal papilla is referred to as epilation. This procedure is focused on the removal of hair at the level of the hair bulb, which is located within the hair follicle. The dermal papilla plays a crucial role in hair growth as it contains blood vessels and cells that help nourish the hair. By breaking the connection between the bulb and the dermal papilla, the hair is effectively removed, often leading to longer-lasting results than other methods such as shaving.

In contrast, exfoliation pertains to the removal of dead skin cells from the surface of the skin, and dermabrasion is a more intensive procedure designed to smoothen the skin's surface by mechanically removing layers of skin. Laser skin rejuvenation primarily targets skin texture, pigmentation, and other skin concerns using laser technology, rather than focusing on the removal of hair from the follicle. Thus, epilation is the correct terminology for breaking the connection you described in the question.
