If the occipital area is still swollen and red after 12 days of hair transplantation, it is considered that the surgical site is infected, which should be relieved through life conditioning, medication and surgical debridement. 1. Life conditioning: Because healthy hair follicles have to be taken from the occipital area, a wound will be left in the area. If you do not pay attention to local hygiene, the local scar healing area is prone to breakage due to poor elasticity, which will lead to increased infection. You should pay attention to the cleanliness of the posterior occipital area and change the pillowcase regularly. 2. Medication: If local infection is identified, anti-inflammatory drugs should be taken orally, commonly used drugs include cefixime and amoxicillin. 3. Surgical treatment: If the redness and swelling is more serious, there are more purulent secretions inside, and there is a clear local abscess, you need to go through surgery to clean up all the pus and decayed tissues and drain them exactly to avoid aggravating the infection. It is recommended that patients with the above situation go to a regular medical institution in time, after examination by a specialist doctor, follow the doctor’s instructions for treatment, and do not use medication arbitrarily during the treatment period, so as not to cause adverse consequences.
