How Long Does Swelling Last After Having a Hair Transplant?

Key takeaways:

• How long does swelling last after a hair transplant? For most patients, swelling improves within a few days and will largely be settled within 5-7 days.
  
• When does swelling usually start after a hair transplant? Swelling can often have a slightly delayed onset and may not be immediately visible after the procedure. It usually becomes noticeable within the first 1-2 days after the hair transplant. 
  
• When is the swelling usually at its worst? From our experience, the swelling peaks usually on the second or third day after your surgery. It happens particularly around the forehead and can sometimes involve the eyelids as well.
  
• Is swelling around the forehead and eyes normal after a hair transplant?  Yes, we often see swelling move down from the scalp to the forehead and around the eyes before it improves.
  
• When should I contact my clinic about swelling? We advise that you get in touch with your clinic if your swelling is getting worse rather than better over time, if it remains significant beyond the first week, or comes with increasing pain, redness, warmth, discharge, fever, eye pain, or visual disturbances.

It is natural to experience some swelling after having a hair transplant, and it is the most common early side effect of the procedure.

Swelling is part of the body’s natural physiologic response to injury. In the vast majority of cases, it settles nicely within a week. Some patients end up with a lot of swelling, while for others it is barely noticeable.

How Long Does Swelling Last After a Hair Transplant?

Days 0–1: Swelling May Be Mild or Not Yet Noticeable

Immediately after the procedure, it is unlikely that you will notice any swelling. It usually takes at least a day before it becomes noticeable. 

Days 2–3: Swelling Usually Peaks

Around the second or third day after your surgery is when your swelling will be at its greatest extent. You will notice it more at this point as the fluid accumulates, and the swelling from the scalp gradually moves downwards to your forehead and even around your eyes, under the influence of gravity. Although this swelling may appear dramatic, it is often part of a normal uncomplicated postoperative swelling pattern.¹

“Some swelling around the forehead and eyes is expected in the first few days and will usually settle on its own. At The Treatment Rooms London, we maintain an open line of communication throughout aftercare, so our patients can feel reassured that our team is there to support them at every stage of their recovery.”

Dr Roshan Vara, Co-Founder and Hair Transplant Surgeon at The Treatment Rooms London

Days 4–5: Swelling Should Start Settling

From the fourth day, you should notice the swelling of your forehead or eyelids beginning to settle down. It generally should improve rather than worsen from this point onwards. If it is not gradually subsiding or is showing signs of increasing redness, tenderness, or pain, you should contact your surgeon for advice.  

Days 5–7: Most Swelling Should Have Resolved

Swelling is normally self-limiting, meaning that no specific treatment is needed to help it go away. By the end of the first week, most or all of your swelling should have disappeared.

Many people see an improvement before this. As mentioned, swelling is usually a mild feature of the post hair transplant recovery process and is not expected to last long.

What If Swelling Lasts Longer Than a Week?

It is possible that you can still have mild swelling present even after a week. If your swelling has continued beyond a week, then you should look at the pattern of the swelling. If it is not gradually improving, then it is time to discuss the swelling with your treating clinic. 

Why Does Swelling Happen After a Hair Transplant?

Swelling is a result of the small incisions made into your scalp when moving hair follicles from the back of your head to the front. This disturbs the scalp and leads to inflammation under the skin surface. The injection of local anaesthetic at the time of the procedure also increases the amount of fluid under the skin. 

The initial swelling can start out at the top of the scalp, but it can end up shifting downwards over time due to the effect of gravity. This is how the swelling can end up dropping to the forehead, and even further down, to the eyelids. It takes time for the excess fluid to be reabsorbed into the bloodstream, but the swelling should be gradually improving as it does so. 

How Can You Reduce Swelling After a Hair Transplant?

The single best proven way of reducing your swelling is by taking the steroid medication that your surgeon recommends. This is an anti-inflammatory medicine, usually used for a few days early on in order to reduce the amount of swelling you experience. Steroids can be harsh on your digestive system, and you will be prescribed a stomach protector alongside it to reduce this effect.²

There is no home treatment that has been proven to completely prevent swelling, it is often an expected post-operative effect and is part of the body’s normal physiologic response to injury –it usually passes on its own. Some things that are widely believed to help include sleeping with your head in a slightly elevated position and using cold compresses.¹

If using a cold compress, do not apply pressure or ice to the recipient area of the scalp under any circumstances. You need to avoid rubbing or pressing against this area. It is best only when applied to the forehead or lower. Cold compressing and elevation are adapted from common principles of how to reduce swelling, and have not been specifically shown to help with post hair transplant swelling.

For swelling around the eyes, you may want to try a gentle massage around them to help facilitate fluid drainage, reduce swelling, and lessen pain.

“Some swelling is expected and is usually mild and self-limiting, but where appropriate we may use medication to help minimise it. We also advise patients on simple measures such as sleeping with the head elevated and avoiding strenuous activities. At The Treatment Rooms London, we provide our patients with detailed aftercare instructions to guide them day by day throughout their recovery journey.”

When Should You Contact Your Hair Transplant Clinic? 

Some swelling is completely expected and an unavoidable part of having a hair transplant. The swelling is not normal if you notice any of the following:

• The swelling is becoming worse rather than improving after the first few days
  
• You have significant swelling that persists after a week
  
• You have increasing pain, redness, or warmth of the scalp
  
• You notice yellow/green discharge or pus
  
• You have a fever or feel generally unwell
  
• Eye swelling comes with eye pain or changes in vision
  
• You have rapid facial or tongue swelling or difficulty with breathing. 

If you notice these symptoms, contact your clinic promptly or, if you can’t get in touch with them, seek urgent medical attention.

Conclusion

Most swelling after a hair transplant has a slightly delayed onset. It begins around a day after the surgery, reaches its peak after 2-3 days, and then gradually subsides.

Make sure to keep up with your aftercare guide, which details which medications to take, how to wash your hair, and care for your newly transplanted scalp in order to avoid complications. Pay attention to signs that things are not quite right and know when to seek medical attention if your swelling doesn’t improve.
