How long does a hair follicle survive after hair transplantation?

Generally, hair follicles can survive within 48 hours after hair transplantation surgery. During the procedure, a strip of scalp containing hair follicles is taken from the back of the head, which is considered the optimal donor area. Under high-powered microscopes, this scalp strip is then dissected into individual follicular units, which are subsequently transplanted into the balding or thinning areas. The general reference price for hair transplantation surgery ranges from 8,000 to 30,000 yuan per session. Noticeable improvement typically occurs 3 to 6 months after surgery, although symptoms such as pain and swelling may occur. Detailed explanation is as follows:

After hair transplantation, the survival of hair follicles is a gradual process. Generally, hair follicles can survive within 48 hours after surgery, with a typical survival rate reaching approximately 90%. This indicates that the follicles can quickly adapt to their new environment and survive. However, stabilization of the follicles takes longer—usually between 10 to 20 days—for them to gradually anchor and stabilize at the transplant site.

During this time, the follicles gradually establish connections with surrounding tissues, forming stable blood circulation and nutrient supply. If the patient has a good constitution and faster metabolism, the stabilization period may be shortened; conversely, if the patient's physical condition is weaker, the recovery time may be prolonged.

To ensure the survival and stabilization of transplanted hair follicles, special attention to post-operative care is necessary. For a period following surgery, patients should avoid strenuous activities and exposure to irritants, while following the doctor's instructions for cleaning and maintenance. This helps the follicles better adapt to their new environment, thereby improving both survival and stability.
