Folliculitis After A Hair Transplant: Why It Happens And What To Do
Last reviewed on 9 August 2026. We review our treatment guides every six months to keep them accurate.
Key points
Small red spots or pustules on the scalp in the weeks after a hair transplant are common and, in the great majority of cases, harmless. This is post-transplant folliculitis, inflammation around the new and existing follicles.
It is one of the most frequently reported things after surgery. A 2026 review of transplant complications describes folliculitis as "one of the most frequently reported postoperative complications following FUE", affecting around 12 per cent of cases.
It usually appears in the first one to four weeks, and a second, later wave can appear around the time the new hairs start to grow through, especially in people with thick or curly hair, where a growing hair catches under the skin like an ingrown hair.
Most of it is not a true infection. Often the pus is sterile, a reaction to a trapped or ingrown hair rather than bacteria, and genuine post-operative infection is rare, under 1 per cent.
It usually clears without harming the result. The review notes that "most cases resolve without sequelae", though an extensive or recurring outbreak should be seen by your clinic, since heavy folliculitis can occasionally affect regrowth.
Mild cases often settle with warm compresses, gentle cleansing and a soothing antiseptic cream; more troublesome cases are treated with antibiotics. It is important not to squeeze or pick the spots.
A few spots are expected and are not a sign your grafts are failing. But if you are worried, or if it is spreading, painful or widespread, your clinic would always rather you asked.
Noticing a crop of red spots or little whiteheads on your scalp a week or two after a hair transplant is understandably alarming, especially when you have invested in the result and are watching the area closely. The reassuring reality is that this is one of the most common and most expected parts of healing, it is usually harmless, and it very rarely threatens the transplant. Knowing what is normal, and what is worth a call to your clinic, takes most of the worry out of it.
This guide explains what post-transplant folliculitis is, why it happens, whether it is an infection, whether it affects the grafts, how it is treated, and when to get in touch with your clinic. It is general information and does not replace your own surgeon's aftercare advice, which always comes first.
What is folliculitis after a hair transplant?
Folliculitis simply means inflamed hair follicles. As DermNet describes it in general, the result is "a tender red spot, often with a surface pustule". After a transplant it shows up as small red bumps or whitehead-like spots around the follicular units, sometimes itchy or mildly sore, scattered across the recipient area and occasionally the donor area too.
It is extremely common. The 2026 complications review lists it as "one of the most frequently reported postoperative complications following FUE", with an incidence of around 12 per cent, and notes it "typically occurs within the first 1 to 4 weeks after surgery, manifesting as erythematous papules or pustules surrounding follicular units". A second, later pattern can appear around week ten as the transplanted hairs begin to grow, particularly in people with thick, coarse or tightly curled hair. So a few spots in the early weeks, and again as growth starts, are part of the normal course rather than a sign that something has gone wrong.
Why does it happen?
It is usually a sterile reaction to trapped or ingrown hairs, not an infection. A later wave comes as new hairs curl under the skin.
There are two slightly different processes, and it helps to know that most post-transplant folliculitis is not really an infection at all.
The most common cause is a reaction to the hairs themselves. The complications review explains that this folliculitis "can be either a genuine infection or, more often, a sterile inflammatory reaction" as the transplanted or regrowing hairs settle in. A second review of transplant complications puts it similarly, describing post-transplant folliculitis as "usually a foreign body reaction to poorly dissected hairs" in which "pus is sterile", meaning the whitehead contains inflammation rather than bacteria. In other words, the body is reacting to a trapped, buried or ingrown hair, not fighting an infection.
The later, week-ten type is a form of pseudofolliculitis, the same thing that causes ingrown hairs after shaving: as a new, often curved hair grows, it can curl back under the skin and provoke a spot. This is why it is more common in thick, coarse or curly hair, and why it tends to coincide with the start of new growth rather than the surgery itself.
Is it an infection?
Usually not. As above, most post-transplant folliculitis is sterile, so it is not contagious and often does not need antibiotics at all. Genuine infection after a modern hair transplant is uncommon: the complications review reports that "the incidence of low and serious infections is rare (less than 1 per cent)", usually linked to poor hygiene, heavy crusting or a pre-existing risk factor. That is a reassuring figure, and it is the main reason a few spots are usually nothing to fear. It also means that if folliculitis is spreading, increasingly painful, or accompanied by significant swelling, warmth or feeling unwell, that is exactly when it should be checked, because those are the signs of the uncommon case that is a true infection and does need treatment.
Does folliculitis affect the transplant result?
In almost all cases, no. The reassuring headline from the 2026 review is that "most cases resolve without sequelae", meaning they clear up without any lasting effect on the transplant. A handful of spots as the scalp heals and the hairs grow is part of normal recovery and does not mean grafts are being lost.
There are two sensible caveats. First, the same review notes that "extensive or recurrent folliculitis may delay hair regrowth and negatively affect graft survival", so while the odd pustule is expected, a busy, spreading or persistent outbreak is worth showing to your clinic promptly rather than leaving. Second, the other review advises treating stubborn folliculitis properly "to prevent cicatricial scarring", the rare situation where prolonged, untreated inflammation could scar. Both point to the same simple rule: minor folliculitis needs only gentle care, but anything extensive or persistent should be treated rather than ignored.
Is it the same as my grafts falling out?
No, and this is worth separating clearly, because both happen in the same weeks and are easily confused. Folliculitis is spots and inflammation on the surface of the scalp. The shedding of the transplanted hairs a few weeks after surgery, sometimes called shock loss, is a separate and also normal process in which the transplanted hairs fall out while their roots stay safely in place, ready to regrow. Our guides on post-transplant shedding and grafts falling out explain that shedding in detail. Spots are not a sign your grafts are failing, and shedding is not a sign of infection; both are usually just healing.
How is folliculitis after a transplant treated?
Most of it needs very little, and the guiding principle is to be gentle and let it settle. The complications review describes management as "primarily conservative", with "gentle cleansing and warm compresses" to soften crusts and help any pustules drain naturally.
For milder cases, many surgeons find that a soothing antiseptic healing cream, such as Sudocrem, applied until the spots clear is all that is needed, alongside that gentle cleansing. More severe, spreading or persistent folliculitis is treated with antibiotics: a topical antibiotic such as mupirocin or clindamycin for localised spots, and oral antibiotics for more extensive cases, sometimes with an antibacterial shampoo. The one firm rule throughout is not to squeeze, scratch or pick the spots, which can worsen the inflammation, introduce infection and, in the recipient area, disturb healing grafts.
Above all, follow your own clinic's aftercare instructions, which are tailored to your surgery, and use their advice on washing, which is a big part of keeping folliculitis to a minimum in the first place. Our guides on redness and healing and antibiotics after a transplant cover the wider recovery. If in doubt about any spot or pustule, your clinic can look at a photo or see you.
When should I contact my clinic?
Contact your clinic if the folliculitis is spreading or widespread, increasingly painful, comes with swelling, warmth, discharge or feeling unwell, or simply is not settling.
A few scattered spots that come and go as you heal are expected and usually need only gentle care. It is worth contacting your clinic if the folliculitis is spreading or covering a large area, if it is increasingly painful, if there is significant swelling, warmth, yellow discharge or crusting, if you feel unwell or feverish, or if it simply is not settling. These are the signs of the uncommon case that needs active treatment, and catching it early protects both your comfort and the result. Because a genuine infection after a transplant is rare, most calls will be reassurance, but your clinic would far rather you asked than waited, and a quick photo is often all they need to advise you.
Where does this leave folliculitis after a transplant?
For nearly everyone, post-transplant folliculitis is a normal, temporary and harmless part of healing rather than a sign that anything has gone wrong. It is one of the most common things people notice after surgery, it is usually sterile rather than infected, it very rarely affects the result, and it mostly settles with gentle care or a simple antiseptic cream. The sensible approach is to expect a few spots, resist picking them, follow your clinic's washing and aftercare advice, and get in touch if an outbreak becomes extensive, painful or persistent. Our general guide on scalp folliculitis covers the condition outside the transplant setting.
If you are recovering from a transplant and unsure about spots on your scalp, the simplest and safest step is always to ask the clinic that treated you, who know your surgery and can reassure or treat you quickly.
Frequently asked questions
Are spots and pustules normal after a hair transplant?
Yes. Small red spots or whiteheads, post-transplant folliculitis, are one of the most common things people notice in the weeks after surgery, affecting around 12 per cent of cases in one review. They usually appear in the first one to four weeks, and again as the new hairs grow through. Most are harmless and clear with gentle care, so a few spots are expected and are not a sign your grafts are failing.
Is folliculitis after a transplant an infection?
Usually not. Most post-transplant folliculitis is sterile, a reaction to a trapped or ingrown hair rather than bacteria, so the pus contains inflammation rather than infection. Genuine infection after a modern transplant is rare, under 1 per cent. That said, folliculitis that is spreading, increasingly painful, or comes with swelling, warmth, discharge or feeling unwell should be checked, as those can be signs of the uncommon true infection.
Will folliculitis affect my transplant result?
In almost all cases, no. A 2026 review found that most cases resolve without any lasting effect on the transplant. A few spots as you heal do not mean grafts are being lost. The exception is extensive or recurrent folliculitis, which can occasionally delay regrowth or, if left untreated, rarely scar, so a busy or persistent outbreak should be shown to your clinic and treated rather than ignored.
How do I treat folliculitis after a hair transplant?
Gently, and usually simply. Warm compresses and gentle cleansing soften crusts and let spots settle, and for milder cases a soothing antiseptic cream such as Sudocrem until they clear is often enough. More severe or persistent cases are treated with antibiotics, topical for localised spots and oral for extensive ones. Do not squeeze or pick the spots, and follow your clinic's washing and aftercare advice, which helps prevent folliculitis in the first place.
Why do I have folliculitis months after my transplant when the new hair is growing?
This later folliculitis is usually pseudofolliculitis, the ingrown-hair effect. As a new, often curved hair grows, it can curl back into the skin and cause a spot, much like after shaving. It tends to appear around the time growth begins, roughly a couple of months in, and is more common in thick, coarse or curly hair. It is generally harmless and settles as the hairs establish, but as always, show your clinic anything extensive or persistent.
