Apr 11, 2022 · The three inner layers become the hair, made up of the cuticle, the cortex and the medulla (although the medulla isn’t always present, especially in hairs with a thinner diameter).

The hair follicle can be divided into 3 regions: the lower segment (bulb and suprabulb), the middle segment (isthmus), and the upper segment (infundibulum). Hair bulbs and mid-segments of hair follicles were micro-dissected from human scalp skin tissues. (A) Pigmented (left) and unpigmented (right) whole anagenic hair follicles; (B) Each hair follicle was further excised using an ophthalmic scalpel under a stereoscope to harvest hair bulbs and mid-segments, as indicated by the arrows (left). ...Hair shedding is a normal part of everyone’s life; on average, a person may lose 50 to 100 hairs daily.
