A follicle is a small sac in the skin or body that holds and protects something. For example, a hair follicle holds and protects a hair. People have follicles all over their body, including on their scalp, face, arms, and legs. When we talk about beauty or skincare, we might say that a certain product helps to nourish or strengthen our hair follicles to promote healthy hair growth. In medicine, follicles can also be discussed in the context of things like ovulation and fertility.
