At present, there are three types of hair transplant hospitals. One is a chain hair transplant hospital. In general, large professional hair transplant hospitals in first-tier cities will open chain hospitals in some second-tier cities for the convenience of some patients. The other is some plastic surgery institutions. These hospitals do not specialize in hair transplant, but only offer hair transplant subjects. Whether the hair can be planted or not, we still have to make a big question mark. In some general hospitals, there is also a contracting department, which is what we often call a hospital.
