A mild headache in the first few days after a hair transplant is common and usually harmless. It tends to come from the local anaesthetic injections, scalp tightness, swelling, a long day in the chair, poor sleep and not drinking enough. For most people it eases within a few days as the scalp settles. A headache that is severe, sudden, getting worse, or comes with fever, a stiff neck, vomiting, confusion or vision changes is different and needs prompt medical attention.
Key takeaways
- A dull, pressure-type headache or a “tight band” feeling around the head in the first days after surgery is common.
- It usually improves within a few days, often alongside the swelling and scalp tenderness.
- Only use pain relief your surgeon has approved. Some common painkillers may not be advised in the first days because of bleeding concerns, and this differs between clinics.
- Rest, fluids, regular meals, and sleeping with your head raised help both headache and swelling.
- Sudden, severe or worsening headache, or headache with fever, stiff neck, confusion or vision problems, needs urgent medical help.
Why a headache happens after a hair transplant
There is rarely a single cause. Several things from surgery day can add up.
Local anaesthetic and scalp tightness. The donor and recipient areas are numbed with many small injections. The fluid used to numb and support the scalp during surgery makes it feel tight and full for a while. It often feels like pressure or a band around the head.
Swelling. Fluid from the recipient area often moves down onto the forehead and around the eyes over the first days. This can feel heavy and pressing. Our guide on how long swelling lasts after a hair transplant and what helps covers this in more detail.
A long, tiring day. A hair transplant often takes most of a day. You sit or lie in one position, often with your neck bent forward or to the side. Neck and shoulder muscle tension is a common trigger for tension-type headache.
Not enough fluids or food. Some people eat and drink little on surgery day because of nerves, fasting before sedation or simply being busy. Low fluid intake and skipped meals can trigger headache on their own.
Sedation and medication. If you had sedation, you may feel groggy or headachy for the rest of the day. Some painkillers and other tablets given after surgery can also cause headache or nausea in some people. You can read more in our guide on anaesthesia and sedation for a hair transplant.
Poor sleep. Sleeping semi-upright to protect the grafts is uncomfortable for many people. A few nights of broken sleep can bring on headaches.
Missing your usual coffee. If you normally drink coffee or tea and skip it around surgery, a caffeine-withdrawal headache is possible. Ask the clinic whether and when caffeine is fine for you.
Travel. International patients often fly home within a few days. Dry cabin air, long waits and little sleep can all make a headache worse.
What is typical: a rough timeline
Every patient is different, and practice varies between clinics. As a general pattern:
- Surgery day and the first night: pressure, tightness and a dull headache are common as the anaesthetic wears off.
- Days 2-4: swelling often peaks around this time and may move to the forehead and eyes. A heavy, pressing feeling can come with it.
- Days 4-7: headache usually fades as swelling goes down and sleep improves.
- After the first week: a new headache, or one that keeps getting worse, is less likely to be from the surgery itself. Mention it to your surgeon or doctor rather than assuming it is normal.
Scalp tenderness, tingling and numbness in the donor and recipient areas are separate from headache and can last longer. See our guide on temporary numbness after a hair transplant.
What helps
Pain relief, only as your surgeon advises
Most clinics give a painkiller plan before you leave. Follow it. Do not add other painkillers, cold and flu remedies or sleeping tablets without checking first. Some anti-inflammatory painkillers and aspirin-type products can affect bleeding, and clinics differ on when they allow them. If you take regular medicine for migraine, blood pressure or anything else, ask your surgeon and the doctor who prescribed it how it fits with your recovery. Do not stop or change a prescribed medicine on your own.

Drink, eat and rest
- Drink water regularly through the day, unless your doctor has told you to limit fluids.
- Eat regular, light meals, especially before taking any tablets that should be taken with food.
- Avoid alcohol in the early recovery period. It can add to dehydration, poor sleep and swelling.
- Rest in a quiet, dim room if light or noise makes the headache worse.
Sleep with your head raised
Keeping your head raised for the first nights helps swelling drain and can reduce the heavy, pressing feeling. A travel pillow can stop you rolling onto the grafts. Our guide on how to sleep after a hair transplant has practical set-ups.
Ease neck and shoulder tension
Gentle shoulder rolls and slow neck movements, without bending your head forward or touching the grafts, can relieve muscle tension. Avoid heavy lifting, straining and hard exercise in the first days, as these can raise pressure in the head and increase swelling.
Cold compresses, carefully
If your surgeon allows it, a cold pack wrapped in cloth on the forehead (not on the grafts) can ease swelling and pressure. Never put ice directly on the skin and never press on the recipient area.
Check your headband or bandage
Some clinics apply a headband or donor dressing. If it feels very tight and is clearly making your headache worse, contact the clinic before loosening or removing it yourself.
When to contact your surgeon or doctor
Get prompt medical help if you have any of the following:
- A sudden, very severe headache, or the worst headache you have ever had.
- Headache with a stiff neck, fever, chills, vomiting, confusion or unusual drowsiness.
- Vision changes, weakness or numbness on one side of the body, difficulty speaking, or a drooping face.
- Headache with chest pain, shortness of breath or fainting, especially after a flight.
- A headache that keeps getting worse after the first few days instead of slowly improving.
- Headache with spreading redness, warmth, increasing pain, pus or a bad smell from the scalp, which can point to infection.
- Headache after a bump or knock to the head.
- Headache that is not controlled by the pain relief your surgeon approved.
For the most serious signs in the first three bullets, call emergency services or go to the nearest emergency department. Do not wait for a reply from the clinic. If you have already flown home, see a local doctor and tell them about your surgery and any medicines you were given.
Common questions
Does a headache mean my grafts are damaged?
No. A headache does not affect the grafts. What matters for the grafts is not knocking, scratching or rubbing the recipient area while they are still fragile, generally in the first 10-14 days.
Can I fly with a headache after a hair transplant?
A mild headache that is improving is usually not a reason to change plans, but follow your surgeon’s advice. Drink water, avoid alcohol on the flight, and keep your head away from the headrest and overhead lockers. See flying after a hair transplant.
I get migraines. Will surgery trigger one?
It can, because of stress, poor sleep and missed meals. Tell your surgeon about your migraines before the procedure and ask which of your usual migraine medicines are suitable around surgery.
