Androgen has obvious inhibitory effect on hair growth. The higher the AR-positive cell rate of dermal papilla, the stronger the effect of androgen, which directly inhibits the growth and development of dermal papilla, makes the hair enter the static stage ahead of time, and is more prone to hair loss. However, the posterior occipital hair follicle contains less AR. After hair transplantation, although the growth environment has changed, the AR value of hair follicles remains at a very low level, maintaining the "donor advantage". Therefore, the implanted hair follicles are not affected by androgen changes, and theoretically, this part of hair follicles will not have hair loss problems in the future. Resources are the key to success. Many patients refused surgery because of the shortage of hair follicle resources in the pillow and the inability to meet the demand for hair follicles in the hair loss area. In order to ensure the ideal effect of hair transplantation, it is necessary to ensure that there are enough donors, so as to ensure the effect of hair transplantation without affecting the beauty of the occipital area.
