Keloid Scarring And Hair Transplants: An Honest Guide
Last reviewed on 31 August 2026. We review our treatment guides every six months to keep them accurate.
Key points
A keloid is a scar that keeps growing beyond the boundary of the original wound. It can follow surgery, a cut, a burn, acne or a piercing, sometimes appearing a year or more after the skin healed, and unlike an ordinary scar it does not fade.
Keloids are more common in people of African, Caribbean, south Asian and Chinese heritage, in people aged roughly 10 to 30, during pregnancy, and in anyone who has formed a keloid before. Even in the higher-risk groups, only a minority of people ever develop one.
They form most often on the chest, shoulders, chin, neck, lower legs and earlobes. The scalp is not among the sites the NHS lists as common, which matters for hair transplant planning, but the risk is never zero.
If you are prone to keloids, the general surgical advice is not to have a hair transplant, and that advice is firmest if a keloid has ever formed on your head. Where the answer is uncertain, the clinic can offer a test procedure: a small incision under local anaesthetic, to see how your skin actually heals before anything bigger is considered.
There is no cure for an existing keloid. Treatment, usually steroid injections, silicone dressings or both, can flatten it and calm the irritation, but cutting a keloid out on its own usually fails: it tends to grow back larger.
If you form keloids readily, say so at consultation. It is central to whether surgery is advisable at all.
Keloid scarring sits behind one of the quieter worries people bring to a hair transplant consultation: not whether the grafts will grow, but what the surgery will leave behind on skin that has overreacted to damage before. It is a fair question, and it deserves a straight answer rather than a reassurance, because for some people the right answer is not to operate.
This guide covers what keloids actually are, who forms them and why, whether hair transplants cause them, and how a clinic should assess you if scars like this run in your skin or your family. For the UK clinical position, the British Association of Dermatologists patient leaflet on keloids is the authoritative source, and the NHS keloid scars page covers the same ground in plainer terms.
What is a keloid scar?
When skin heals, scar tissue forms, and it is common for a scar to sit slightly proud of the skin at first. A scar that stays thickened but keeps to the shape of the original wound is called a hypertrophic scar, and it usually flattens and fades over time. A keloid is different: it overgrows the wound that started it, spreading into skin that was never injured, and it may be permanent.
Keloids happen when the skin overproduces collagen, its structural protein, during healing. The British Association of Dermatologists notes they can follow very minor damage, an acne spot is enough, and occasionally appear with no obvious trauma at all. They are typically raised, firm, smooth and shiny, sometimes itchy or sore while they are growing, and they can appear anywhere from three or four weeks after a wound to more than a year later.
Who is more likely to form keloids?
Anyone can form a keloid, but the risk is not evenly spread. The NHS lists people of Black African, African Caribbean, south Asian and Chinese origin as more likely to develop them, along with people aged 10 to 30, people who are pregnant, and anyone who has had a keloid before. A StatPearls clinical review puts the incidence in darker-pigmented populations at between 4.5 and 16 per cent, several times the rate seen in white Europeans.
The tendency can run in families: the British Association of Dermatologists reports that 5 to 10 per cent of Europeans with keloids have at least one affected family member. Location on the body matters as much as ancestry, with the chest, breastbone, shoulders, chin, neck, lower legs and earlobes the classic sites, the earlobe most familiarly after piercing. Wounds that become infected, or that heal under tension, are also more likely to keloid.
It is worth keeping the risk in proportion: even in the highest-risk groups, most people never form one, and having darker skin does not mean expecting a keloid every time the skin is broken.
Do hair transplants cause keloid scars?
Any surgery can trigger a keloid in someone prone to them, and a hair transplant is surgery, so the honest answer is that the risk exists. But three things keep it low in practice.
First, the wounds are tiny. An FUE transplant frees each follicle through a punch under a millimetre wide and places it through an incision smaller still, so the surgical injury is spread across thousands of pinpoint sites rather than concentrated in one cut. There is no wound to close, no stitches, and no healing under tension, which the StatPearls review identifies as a contributor to keloid formation. The older strip method leaves a long sutured wound instead, which is one more reason FUE is the only method used at My Hair UK.
Second, the scalp is simply not where keloids like to grow. The common sites run down the front of the body and the ears; the scalp does not appear on the NHS list. That is an observation about probability rather than a promise, and it is exactly the kind of claim a surgeon should weigh against your individual history rather than recite.
Third, a separate condition deserves a mention because it looks like the exception: acne keloidalis nuchae, which causes keloid-like bumps and scarring at the nape of the neck, mostly in Black men. Despite the name it is not true keloid disease, but because the nape borders the donor area it is assessed in its own right at consultation.
Can you have a hair transplant if you are prone to keloids?
The straight answer from the surgical team is that if you are prone to keloid scarring, the general recommendation is not to have a hair transplant, and that recommendation is firmest where a keloid has ever formed on your head. A tendency that has already shown itself on the scalp is not a risk worth trading for density.
At consultation the surgeon should take a proper healing history: previous keloids and where they formed, how piercings, cuts, operations and acne have healed, and whether keloids run in your family. Existing scars are examined, because the difference between a hypertrophic scar that faded and a true keloid that spread matters here. One raised scar on the chest a decade ago is a different conversation from active, spreading keloids on the jaw.
Where the history is uncertain, or keloids have formed elsewhere on your body but never on your head, the clinic can offer a test procedure: a small incision made under local anaesthetic, left to heal, and reviewed to see how your body actually responds before any transplant is considered. Keloids can take months to declare themselves, so this is a slow answer, but it is a real one, measured in your own skin rather than in anyone's reassurance. A clinic that sometimes says no is the kind you want assessing you, and keloid risk is one of the honest reasons that answer exists.
People with the scarring hair loss CCCA should know their condition carries its own raised keloid tendency on top of everything above; our guide to central centrifugal cicatricial alopecia covers why transplantation there is a special case. And because keloid screening is part of how afro-textured transplant work is planned more generally, our afro hair transplant page sets out where it fits in that assessment.
What if you already have a keloid?
An existing keloid is a job for a GP or dermatologist before it is a job for anyone else. There is no cure, but treatment can flatten a keloid and settle the itch and soreness. The British Association of Dermatologists lists steroid injections into the keloid as the most common treatment, typically repeated monthly over several months, with silicone gels and dressings available from a pharmacy without prescription, and compression, cryotherapy, laser and radiotherapy used in selected cases.
What does not work is simple removal. Cutting a keloid out creates a larger wound in skin that has already shown what it does with wounds, and the keloid usually returns bigger unless excision is combined with other treatment. The NHS puts it flatly: surgery to remove a keloid scar is not usually recommended because it is likely to grow back larger. No hair transplant should be placed into or immediately around an active keloid, and a scalp keloid needs a dermatologist's assessment first.
Reducing the risk if you are prone
Keloids cannot be reliably prevented, but the NHS advice for people who form them is practical: avoid elective skin damage you do not need, tattoos and piercings above all, and treat acne early so it does not scar. For surgery you do choose, the protective step is disclosure: tell the surgeon about every keloid and every odd scar before the procedure, not after, so the plan, the technique and even the decision itself can take them into account.
If you have noticed hair loss and are weighing up what to do about it, our guide to hair loss in afro-textured hair covers the causes most relevant to the skin types keloids favour, and the surgical route itself is explained on our FUE hair transplant page.
When should you see a doctor?
See a GP about any raised scar that is still growing, itching or sore, especially one spreading beyond the original wound: treatment works best on younger keloids, and a GP can refer you to a dermatologist if needed. A scar can usually be diagnosed by examination alone. This guide is general information and not a substitute for that assessment.
Frequently asked questions
Can you get a hair transplant if you have keloid scars?
The general surgical advice is not to, if you are prone to them, and especially not if a keloid has ever formed on your head. Where the history is milder or uncertain, the surgeon reviews how your skin has healed elsewhere, and the clinic can offer a small test incision under local anaesthetic to see how your body reacts before any transplant is considered.
Do FUE hair transplants cause keloid scars?
Rarely. FUE spreads thousands of pinpoint wounds, each under a millimetre, across the scalp, with no cut to close and no tension in the healing skin, and the scalp is not among the body sites where keloids commonly form. The risk is low rather than zero, which is why a proper healing history is taken before surgery.
Are keloids more common in Black skin?
Yes. People of Black African, African Caribbean, south Asian and Chinese origin form keloids more readily, with reported rates in darker-pigmented populations of roughly 4.5 to 16 per cent. Even so, most people in every group never develop one, and skin tone alone neither predicts a keloid nor rules out surgery.
Can a keloid scar be removed?
Not reliably. Cutting a keloid out usually produces a larger one in its place, so excision alone is not recommended. Treatment aims to flatten and settle the scar instead: steroid injections are the most common approach, alongside silicone dressings, compression, cryotherapy, laser and, after surgical removal in selected cases, radiotherapy. A dermatologist guides the choice.
Does a keloid tendency run in families?
It can. The British Association of Dermatologists reports that 5 to 10 per cent of Europeans with keloids have an affected family member, and family history is one of the recognised risk factors. If your relatives form keloids, mention it at any surgical consultation even if you never have.
