It is actually quite normal to notice pimples after a hair transplant. However, these are actually not the same as acne. In the case of common or androgenic acne, dirt or skin cell debris (from the pore-lining) blocks the skin pore opening, causing a buildup of oil beneath the surface.
Some patients are alarmed to find newly developed bumps on their scalp following their hair transplant procedure. Dr. U answers the question of why these oc…
Reasons Why Pimples After a Hair Transplant May Form
In this video, Dr. Umar explains that bumps after a hair transplant develop as a result of two issues in the grafted area:
- Folliculitis, or inflammation of the hair follicle
- Ingrown hair formation
Causes of Folliculitis Pimples After Surgery
Folliculitis bumps after a hair restoration procedure usually result from infection caused by fungi or bacteria. The most common microbial cause is the staph (staphylococcus) bacteria. Hair follicles can become blocked or infected, causing redness and raised bumps above the skin.
Folliculitis may also arise from ingrown hair, which is then attacked by the immune system, resulting in raised red bumps. A few months after a hair transplant, the new hair growth may trigger inflammatory reactions.
Hair Transplant Acne at the Recipient Area
At about 3 months following a hair transplant surgery, new hair shafts will start to grow and emerge upwards. When they contact the skin above, the hair can trigger irritation and inflammation—the swelling forms what looks like pimples after a hair transplant. In a way, bumps after a hair transplant are actually a very positive sign, indicating that new growth is on its way.
On the other hand, bumps may form if the sebaceous glands attached to the hair follicle continue to release the oil, producing cysts.
Ingrown Hair After a Hair Transplant
Resistance from the skin may cause the hair to curl downward. And this forms ingrown hair. The ingrown hair may cause an inflammation reaction in the skin or the hair follicle. This is another way pimples after a hair transplant can form.
Never Pop Hair Transplant Pimples
One or two bumps should resolve on their own. If you notice a much larger number of pimples after a hair transplant, don’t try to pop them. This can result in further inflammation and greater complications. Instead, report the issue to your surgeon.
Your hair transplant doctor may prescribe medication to reduce the inflammation. Or he or she may surgically remove them.
Ultimately the right treatment will target the specific cause responsible for the formation of the hair transplant acne, particularly at the recipient area.
Not Everyone Will See Bumps After a Hair Transplant Procedure
The formation of small pimple-like structures is a rather common occurrence. But not all patients will experience this. In fact, if you don’t see bumps forming by about the third month, this doesn’t mean that your hair is failing to grow!
Although new signs of growth after a hair restoration surgery typically emerge by the third or fourth month, some people may notice new hair formation as late as 9 to 12 months after their procedure.
