Immediate side effects:
Pain - Though usually minor, It is common to feel some pain or discomfort following your hair transplant surgery. In most patients, the pain lasts up to five days. Generally, over-the-counter painkillers like paracetamol should help suppress this pain.
Swelling - Inflammation around your head, eyes and cheeks is widespread in patients following a hair transplant.
Itchiness - Itchiness may be one of the most frustrating hairline transplant side effects. However, it is paramount for your hair surgery's success that you entirely refrain from itching your scalp. The transplanted hair follicles remain fragile for the first week or so, meaning they can easily be relocated or killed off with any physical stress to your scalp. Fortunately, if your scalp is itching, it is an excellent sign that your head is healing correctly.
Scabbing - Like itchiness, scabbing also lasts for around ten to fourteen days after hair restoration surgery.
Infection - Infection after a hairline surgery is incredibly uncommon. The occurrence of infection is heavily dictated by the practices of your chosen hair clinic.
Common symptoms of infection are as follows: noticeably increased pain, the creation and discharge of pus from your scalp.
Reaction to anaesthetic - Finally, reactions are certainly the most dangerous of all immediate side effects with hair plugs and surgical procedures in general. Measures to avoid all risks associated with anaesthetic reactions should be discussed and practised in the consultation(s) leading to your hair transplant surgery. The symptoms following a reaction vary between patients but include a rash, hives, severe itchiness, swelling, drop in blood pressure, shortness of breath, coughing, etc. Fortunately, reacting to anaesthesia is extremely rare and largely preventable.
Subsequent side effects:
Nerve damage - Numbness around the scalp can occur following hair transplant surgery. The numbness stems from anaesthesia reaching the nerves on your head. Though most patients only feel numb for a few days following the surgery, few have reported numbness lasting a few weeks or even a few months. Like infections, the chances of having long term numbness are low, but it is ultimately the doctor's responsibility to administer the anaesthetic correctly.
Scarring - Though the scar severity of FUT hair transplants trumps FUE, both do leave scars. Fortunately, after a few weeks (based on the extraction quality of the surgery), scars from robotic FUE hair transplants become virtually undetectable. With FUT, a linear scar at the nape of your scalp will be permanent.
Hair loss may reoccur - The donor area at the nape of the scalp is DHT (Dihydrotestosterone) resistant. This resistance allows the transplanted hair to be permanent. However, the hair surrounding your transplant is still subject to the natural ageing process. Due to this, some patients decide to have a second set of hair implants around ten years after the first.
