Hair bulbs.

DNA damage was repaired, and ordered hair bulb structures were restored within 96 hours. Bulge stem cells did not undergo apoptosis nor proliferation. K5 + basal lower proximal cup cells and outer root sheath cells quickly replenished the cells in the germinative zone and regenerated the concentric layered structures of the lower HF segment.

The anagen hair follicle was surrounded by the basket-like capillary network which was supplied by the branches of the subcutaneous artery and ...The living part of the hair is the follicle and is the only part fed directly by the capillaries. The cells in the bulb divide every 23 to 72 hours, faster than any other cells in the body. Due to this, the hair can be used to trace metabolic deficiencies, a possible storage of heavy metals, metabolic toxicity, etc.
