Hair Transplant Gone Wrong: Repair and the Technician Problem

When a hair transplant goes wrong, it usually does so in a few recognisable ways: an unnatural hairline, poor growth, hair pointing the wrong way, visible scarring, or a donor area left thin by over-harvesting. Many of these trace back to planning and to who performed the surgery, and some can be improved by repair, but not every patient can be helped.

This guide covers what goes wrong, the black-market problem behind many failures, what repair involves, and how to avoid ending up needing one. It names no clinics or people. For the procedure itself, see our main guide to what a hair transplant is and how it should be done.

The common failures

The International Society of Hair Restoration Surgery (ISHRS) sets out the problems its members see in repair work. They fall into a handful of groups.

• Unnatural hairlines. Lines placed too low or too straight for the face, often designed for the present rather than for later.
• "Pluggy" grafts. Older techniques used larger grafts that can look coarse; some people still live with these results.
• Wrong direction or angle. Hair that grows out at an angle unlike the surrounding hair.
• Poor growth. Grafts that did not take, leaving thin or patchy coverage.
• Grafts in the wrong place or at the wrong time. For example, a crown filled too early in a young patient, using up donor hair.
• Over-harvesting. A donor area left thin or "moth-eaten" because too many grafts were taken.
• Scarring and infection. Visible scars, and infections picked up during or after surgery.

The technician problem

A large part of the problem is surgery performed by people who are not qualified to perform it. The ISHRS has run its Fight the FIGHT campaign since 2019 against unlicensed non-physicians doing hair-restoration surgery.

The campaign names clinics in Turkey, Iran and several European countries that it says draw patients with low prices and promises of guaranteed results, and "turn-key" set-ups in the US and Canada where physicians hire technicians to harvest grafts, design hairlines and make scalp incisions. It lists the consequences as scarring, unnatural hairlines, poor growth, wrong hair direction, depleted donor areas and infections, often with little recourse for the patient.

How often surgeons see it

ISHRS members see the results in their own practices. In the society's 2025 practice census, members reported that repairs of earlier black-market transplants made up 10% of their cases on average, with a median of 5%. Asked whether black-market clinics operate in their city, 59.4% said yes.

These are members' reports about their own practices, not a measure of how many transplants go wrong worldwide. They do show that repair is a routine part of reputable surgeons' work.

The travel dimension

Many people now travel for surgery, and distance adds risk: aftercare, follow-up and any complaint become harder once you are home. The UK Foreign Office's travel advice for Turkey says it is aware of 7 British nationals having died in Turkey in 2025 following medical procedures, and advises discussing plans with a UK doctor first.

The Foreign Office does not say which procedures were involved, and we make no claim about hair transplants in particular. The general lesson applies to any surgery abroad: know who will operate, how complications will be handled, and who will see you at home if something goes wrong.

What repair can do

Repair surgery can often improve a poor result, though it rarely makes it as if the first surgery never happened. The ISHRS describes several approaches.

• Removing grafts. Unnatural grafts, such as a hairline set too low, can be removed completely or partly.
• Moving grafts. The ISHRS says FUE has made it possible to take out unnatural grafts and often relocate them to a more suitable place.
• Adding grafts. More grafts can soften a harsh line or add density, if donor supply allows.
• Camouflage. Scalp micropigmentation, a cosmetic tattoo technique, can make thin areas or scars less visible.

Repair takes time and often more than one procedure. Each step uses donor supply, which a failed first surgery may already have depleted.

What repair can't do

Repair is limited by the donor area. The ISHRS says plainly that not all patients can be helped, and that a lack of donor hair is a reason not to perform surgery.

An over-harvested donor area can't be refilled, because the extracted follicles are gone. Scars can often be camouflaged but not erased. This is why prevention matters so much more than repair in hair restoration, and why our guide to the donor area and over-harvesting stresses planning from the first session.

If you think your transplant has gone wrong

Start by giving it time, unless you have signs of infection. Transplanted hair sheds and regrows, and the American Academy of Dermatology says most results show between six and nine months, and some take 12. What looks like failure at three months is often normal.

If you have warning signs such as spreading redness, pus, fever or bleeding that won't stop, contact your clinic or seek urgent care the same day; our guide to hair transplant side effects lists them. If growth is still poor after a year, or the design looks wrong, ask the original clinic for a review and get an independent opinion from a qualified surgeon. Bring photos, dates and any records of the procedure.

How to avoid needing a repair

The best protection is the questions you ask before any surgery. At each consultation, ask:

1. Who will harvest the grafts, make the incisions and place them, by name and qualification?
2. How many grafts will you take, and how much donor supply will remain?
3. How will the hairline look if my hair loss continues?
4. What happens if grafts don't grow, and who manages complications?
5. Who will see me after surgery if I live elsewhere?

A GP or dermatologist can confirm the diagnosis first, and the ISHRS Find a Doctor directory and the society's Fight the FIGHT pledge list are free ways to check surgeons. None of them pays us.

Keeping records from the start

If something does go wrong, records make every next step easier. Before surgery, keep copies of your consultation notes, the written plan, consent forms, the number of grafts proposed and the names and roles of everyone involved. After surgery, keep the aftercare instructions, receipts and a dated photo series. A repair surgeon, a complaint, or simply a second opinion all start from knowing exactly what was done.
