The new hair follicle implanted by hair transplant surgery needs to adapt to the new environment and establish new blood circulation, which requires a certain recovery time. Generally speaking, most patients with alopecia will undergo hair transplant and stubble replacement surgery about half a month or a month after surgery, and hair loss will occur in the planting area. This is a normal phenomenon, and friends don't have to worry too much. Hair begins to grow about 3-4 months after the operation, and a final effect will be achieved after one year. The later dyeing and perm is not affected.
