Around 50% of men experience a certain degree of hair loss by their 50s. Many men experience hair loss during their 20s and 30s.
Hair loss occurs mostly in the front parts of the scalp while the rear parts remain intact. Hair transplant (is this called transplant or transplantation?) is a procedure which consists of an extraction loss resistant (don’t understand) for a transfer to bald areas. The transferred follicles survive in their new habitat and produce strands of hair again.
