Hair Follicles in Skin Layers

This illustration provides a clear anatomical view of hair follicles embedded within the various layers of the skin. It shows the hair strands emerging from the surface, the follicles extending deep into the dermis, and connecting with underlying blood vessels (depicted in red and blue) that provide nourishment. The diagram also hints at sebaceous glands, shown as yellowish structures surrounding the upper part of the hair follicles, which are responsible for producing sebum to lubricate the skin and hair. It's a helpful visual for understanding the intricate structure and support system of human hair.
