Dr. Xu Xia said that the main cause of hair loss is the stimulation of androgen, and the hair follicle in the back pillow is not sensitive to the change of androgen, so it will not fall off. Based on this phenomenon, posterior occipital hair transplantation has become the most effective and convenient method to treat alopecia. More and more alopecia patients have benefited from hair transplantation and successfully got rid of hair loss. After operation 1- 10 day: the new hair can grow to 5 mm;
10- 20 days after operation: the new hair grows to about 1 cm;
1-3 months after operation: the transplanted old hair was pushed out by new hair, and the hair growth length was uneven;
3-6 months after operation: 95% of new hair grows out, from uneven and soft to normal hair, which can be trimmed;
9 months after operation: you can comb your hair freely, which varies from person to person.
