Scalp reduction is a surgical treatment to remove parts of the scalp that are affected by alopecia (hair loss), the purpose being to reduce the overall area of bald skin. The healthier parts of the scalp are then stretched and re-positioned, making the balding area smaller and more manageable. The treatment can be done in isolation but is often used in conjunction with a hair transplant procedure.The final result is seen in the image. Provided by @saeedhajizadehh
