Glossary Primary Hair Follicles

initial hair-producing structures formed during fetal development

Primary hair follicles are the initial hair-producing structures that develop in the skin during fetal development. These follicles typically give rise to thicker, coarser hairs, such as those found on the scalp, eyebrows, and eyelashes. They are distinct from secondary hair follicles, which produce finer, shorter hairs like those on the body and face.
