The biggest disadvantage of SFT ultra-micro needle hair transplant is that it is more expensive than ordinary hair transplant surgery, because this surgery is one of the most difficult hair transplant techniques in the hair transplant industry at present, which can achieve the same density and naturalness as the original hair growth, and the growth effect after surgery is the same as the original hair growth, and the corresponding price is also a little expensive. But the overall effect is also the best in the current hair transplant technology. Because of the high precision of SFT ultramicro needle, it has high requirements for hospital hardware and doctors, so it is difficult to popularize it widely. At present, only Sino-German hair transplant and plastic surgery hospitals can mature the implementation of ultra-fine needle technology. At the same time, the operation time is relatively long, which requires more doctors and higher requirements for the overall level and cooperation of the doctor team.
