Acne keloidalis nuchae, also known as “AKN”, “acne keloidalis” or “folliculitis keloidalis”, is a painful type of folliculitis that can sometimes appear after a close shave or haircut. The disease develops when hair follicles become inflamed. While the body tries to heal itself, a new thick, scar-like tissue begins to form after the preliminary inflammation. The first few times these harsh, painful bumps appear on the back of the head, it is easy to mistake them for a common case of razor burn, but the truth is a little more long-lasting than a case of skin irritation. Over-the-counter drugs and antibiotic prescriptions from certified dermatologists can only help keep the bumps at bay by managing pain and symptoms temporary relief, and not by curing. There are, however, viable treatment options for bumps on back of head after haircut. Here’s how you can cure the big bump on the back of your head: to truly rid the back of the head from these unruly bumps, there is a special acne keloidalis nuchae removal surgery that permanently removes these unsightly bumps. 

Acne Keloidalis Nuchae: The Basics

The condition often referred to as AKN typically affects men between the ages of 13 through 25. It is thought to be more likely to develop in hispanic men and men of African descent based off of the structure and growth patterns of the hair follicles, as well as the prevalence of short, closely shaved hairstyles within this community. Since the possibility of growing more tightly coiled, curly, coarse hair is higher, so is the chance of developing mild to chronic acne keloidalis nuchae. This results in 0.45% of every case of dermatosis being within the population of men of color. It is believed that the improper regrowth of hair, particularly after a close shave, cause skin irritation, thus resulting in the swelling of follicles, creating lesions of keloid-like scarring. While AKN does not always appear after fresh, close shaves and haircuts, it is proven to be more likely. However, another popular thought shared by many dermatologists, including Dr. Umar, is that AKN may be related to hormone disbursement in the body. These would refer to the same hormones that cause common bumps in various places on the skin known as pimples.

Symptoms of Acne Keloidalis Nuchae

Got a few bumps on the back of your head after a haircut and think it might be AKN? Generally, the first symptom is a collection of bumps that are also known as papules and pustules. These papules can be filled with a white discharge, resulting in the misconception that they are merely pimples. While the condition starts off as simple, pimple-like bumps on the back of the head, if left untreated the bumps eventually join together to create a single mass formation of thick scar-like tissue.

During this progress of the condition, it is not uncommon to see broken or ingrown hairs surrounding the mass build up. But it is important to remember that in severe cases, this advancement can result in permanent hair loss. Beside the unappealing aesthetic nature of the bumps, acne keloidalis nuchae can become quite painful and itchy producing pruritus. Pruritus is a particular itch that can be associated with dry skin, specific skin diseases and more. Note that in more severe cases, pus and a bloody (or sometimes clear) discharge is noticed to leak from the lesions. While the symptoms look and feel uncomfortable, it is important to remember that these masses are benign.

Unique Incision by Dr. U to Treat AKN Bumps on Back of Head After Haircut

Dr. U’s expertise in acne keloidalis nuchae removal surgery led to the birth of his tried and true “Bat” incision technique. This unique method of removal requires the complete surgical extraction of the growing lesion mass from the back of the head. The unique incision shapes encourage healing that results in more normal looking scar line that forms the new posterior neck hairline. Typically, scarring after a surgical removal can be just as visible as the initial condition but patients have responded positively to Dr. U’s distinct method even stating that after months or years of growing their hair out to hide their AKN lesions, they can finally cut their hair short again. After cutting out the lesion, Dr. U’s incision method strives to result in a disguised, healed scar that is most camouflaged along the posterior hairline. This very reason is why clients continue to seek out the specialized prowess of Dr. U. Watch below to see real patient testimonials!
