Frictional alopecia is the loss of hair that is caused by rubbing of the hair, follicles, or skin around the follicle.

Skin expansion is a common surgical procedure to grow extra skin through controlled mechanical overstretch. It creates skin that matches the color, texture, and thickness of the surrounding tissue, while minimizing scars and risk of rejection. [1] When skin is stretched beyond its physiological limit, mechanotransduction pathways
Blood vessels soon grow into the dermis, restoring circulation. If the injury is very minor, the epithelial cells eventually restore the epidermis once the dermis has been regenerated. In major injuries, the repair mechanisms are unable to restore the skin to its original condition.
The vas deferens can grow back together after a vasectomy–thus resulting in vasectomy failure. [40] This occurs due to the fact that the epithelium of the vas deferens, similar to the epithelium of some other human body parts, is capable of regenerating and creating a new tube in the event that the vas deferens is damaged and/or severed.

Timing is important to wound healing. Critically, the timing of wound re-epithelialization can decide the outcome of the healing.
