The term "follicular" refers to anything related to a follicle, which is a small sac or cavity in the body. Follicles are found in various organs, such as the skin, ovaries, and hair. For example, in the ovarian context, follicular development is crucial for the maturation of eggs, which are essential for reproduction. In the context of hair, "follicular" describes the hair follicles that produce and grow hair. Each hair follicle goes through cycles of growth, rest, and shedding. Understanding follicular health is important for addressing issues like hair loss and maintaining healthy scalp conditions.
