Pimples After a Hair Transplant: Is It Okay to Squeeze Them? Folliculitis and Signs That You Need Medical Care

1. What Are Pimples and Folliculitis After a Hair Transplant?

"Pimple" is an everyday term for a small bump that appears on the skin. This term alone cannot determine a diagnosis. Folliculitis is inflammation of the hair follicles, where hair grows, and it may be accompanied by red bumps, itching, tenderness, or pus. [1]

If bumps appear on the scalp after surgery, it is necessary to check whether this is inflammation around the hair follicles or another skin change. Whether it is in the recipient area or the donor area, when it started, and how it is changing are also useful information for the consultation.

2. They May Look Similar but Have Different Causes

Medical staff review both your medical history and skin condition, and if an infection is suspected, they may consider a specimen test as needed. Therefore, it is difficult to distinguish infectious from non-infectious inflammation based only on the color or shape of bumps in a photo. [1]

3. Does a Pimple Mean the Transplanted Hair Failed to Take?

The appearance of a pimple alone does not establish graft failure. At the same time, it cannot be guaranteed that no inflammation affects the transplanted hair. The populations studied and the outcomes measured in research need to be considered separately.

2024 Study: Folliculitis Incidence Observed in 1,317 Patients

The study by Zhou et al. retrospectively analyzed the records of 1,317 patients who underwent hair transplants at four medical institutions and completed 9 months of follow-up. In this group, the incidence of post-surgical folliculitis was 12.11%. [2]

Here, 12.11% is the incidence of folliculitis in that study population. It is not a graft failure rate, the incidence at any particular clinic, or a probability that applies directly to an individual. Because it is an observational study analyzing past medical records, it is difficult to generalize directly to situations with different patients or different surgical and care conditions.

2010 Study: A Recovery Course Was Reported, but It Does Not Represent All Cases

The study by Bunagan et al. retrospectively compared 27 patients who developed folliculitis after strip hair transplantation (FUT) with 28 who did not. In the folliculitis cases included in the study, the lesions were reported to have resolved without scarring or reduced growth of transplanted hair. [3]

However, the sample was small and the study examined the course after a specific surgical method. It should not be interpreted as predicting the same course for folliculitis of every cause and severity, or as evidence that consultation and treatment are unnecessary.

4. How Should You Respond at Home?

Before the cause is identified, checking the care instructions from the clinic that performed your surgery should take priority over trying to remove the bumps yourself.

1. Do not squeeze them with your fingers or prick them with a needle. This risks further damaging the skin or spreading infection. Whether a procedure to drain pus is needed should be decided after a consultation.
2. Do not add new ointments or antiseptics on your own. Rather than immediately applying leftover antibiotic or steroid ointment, ask whether you should use it. Use medications already prescribed as directed, and consult medical staff if a change is needed.
3. Wash at the time and in the way you were instructed. Do not scratch with your fingernails or rub hard, and confirm the washing method suited to your current stage after surgery.
4. Record changes and pass them on. Organize, together with photos, the date you first noticed them, their location, number and extent, and changes in pain and discharge.

The advice to avoid self-squeezing takes into account both the American Academy of Dermatology (AAD)'s general guidance on boil care and the NHS's principles of care after a hair transplant. It does not mean there are clinical trial results comparing the effects of squeezing pimples yourself after a hair transplant. [4] [5]

5. Do Not Delay Seeking Care If You Notice These Changes

If the following symptoms newly appear or worsen quickly, contact the clinic that performed your surgery immediately and seek prompt care. If you cannot reach them, you should be evaluated at a nearby medical facility.

• If the red area spreads quickly: Check for redness spreading to the surrounding area and changes in swelling and warmth.
• If pain suddenly worsens or is very severe: Report any pain that was not expected during recovery or that is getting worse.
• If fever, chills, or general malaise occur: Also watch whether your overall condition worsens along with the scalp symptoms.

Mayo Clinic describes a rapid increase in redness or pain, fever, chills, and general malaise as signs that may suggest a spreading infection. The NHS also advises contacting the clinic that performed the surgery promptly if severe pain or unexpected symptoms occur after a hair transplant. [6] [5]

Even without such sudden changes, if pimples keep recurring or do not improve, ask about scheduling a consultation. There is no need to assume it is part of normal recovery just because the bumps are small, nor, conversely, to take every case as graft failure.

6. When Contacting the Clinic, Prepare Photos and This Record

Preparing an overall photo showing which area is affected and a close-up photo showing the bumps and surrounding skin makes it easier to convey location and changes. Take photos in a bright place without filters, and keep comparison photos under the same lighting and angle as much as possible.

• Dates: The surgery date and the date you first noticed the pimples
• Location: Whether it is the recipient area or a donor area such as the back of the head
• Changes: Whether the number or extent has increased, and whether there is discharge
• Symptoms: Whether there is pain, itching, warmth, or fever
• Products used: Prescription medications and any newly applied ointments, antiseptics, shampoos, etc.

This list is a guide to help you convey your symptoms completely. If symptoms are severe or worsening quickly, do not delay care to prepare records or photos.
