What is Folliculitis Decalvans?

Published on March 16, 2022. Last Updated on July 1, 2024.

What is Folliculitis Decalvans: Folliculitis Decalvans (FD) is a rare, chronic (long-term) cicatricial (scarring) alopecia that occurs in adults. FD occurs on the scalp and is known to cause permanent hair loss due to the scarring and prolonged autoimmune response associated with it.

Folliculitis Decalvans is derived from Latin and means “inflammation of the hair root associated with hair loss.”

Specifically, Folliculitis Decalvans (FD) is classified as primary cicatricial or scarring alopecia, a group of disorders in which the inflammatory process targets the hair follicle, resulting in follicular destruction (hair loss) that can eventually lead to permanent hair loss.

Symptoms of Folliculitis Decalvans

Some of the reported symptoms associated with FD include:

  1. Temporary or Permanent Hair Loss
  2. Patchy Hair Loss
  3. Irritated Spots
  4. Pimple-Like Sores Around Affected Area
  5. Pain and discomfort Centered Around the Affected Area
  6. Tufting of Hairs Growing Out of a Single Follicle
  7. Redness or Swelling of Affected Area
  8. Scaly or Crusted Patches of Skin Surrounding Affected Area
  9. Scarring of the Scalp

What Causes Folliculitis Decalvans

The cause of Folicululitis Decalvans (FD) is currently unknown. Medical experts speculate that this condition may be caused by an abnormal response to bacteria, particularly Staphylococcus aureus.

On the other hand, Dr. Sanusi Umar of Dr. U Skin & Hair Clinic, AKA The Bumpinator, believes that Folliculitis Decalvans (FD) may be associated with another condition, also currently being studied, called Acne Keloidalis Nuchae (AKN) [1].

Based on these associations between Acne Keloidalis Nuchae and Folliculitis Decalvans, which may be able to be treated using Dr. Sanusi Umar, AKA The Bumpinator’s own invented methods, using his invented procedures and equipment, this new finding may pose as a significant and novel milestone within the medical community, as Dr. U is one of the few doctors nationwide, if not in the world, who has been able to successfully treat both of these currently unknown conditions using his personalized methods and procedures.

Dr. U is a pioneer in Acne Keloidalis Nuchae research and removal and has been successfully referred by many doctors for severe cases of AKN removal.

Additionally, Dr. U supports the finding that Folliculitis Decalvans mostly affects people of color [1].

Dr. U, AKA The Bumpinator, has documented this possible association between Acne Keloidalis Nuchae and Folliculitis Decalvans in his published AKN Classification paper here.

What Folliculitis Decalvans is Not

FD is not a contagious condition, a type of skin cancer, or a keloid.

Who is Affected by Folliculitis Decalvans (FD)?

Folliculitis Decalvans is a relatively rare condition that accounts for 3% of 3133 diagnoses of alopecia and 11% of 840 diagnoses of cicatricial alopecia [2]. 

FD affects both men and women, but men more commonly. It is not known to be hereditary, although there are reports of it affecting members of the same family.

As previously mentioned, Dr. Sanusi Umar, AKA Dr. U or The Bumpinator, believes that Folliculitis Decalvans (FD) tends to affect mostly people of color [1].

Does Folliculitis Decalvans Hurt?

Patients who have had Folliculitis Decalvans are known to report pruritus (skin itching) or pain. FD can cause the area of the scalp to become itchy and painful, sometimes feeling tight. At other times, no discomfort may be felt.

What Does Folliculitis Decalvans Look Like?

FD generally presents as an “expanding patch of alopecia with peripheral pustules on the scalp.”[3]

The affected scalp area may become red and swollen, forming scaly areas, scabs, and crusts. Pus-filled nodes may develop, most commonly on the back of the head, but any other part of the scalp may be involved [4].

Another characteristic feature of Folliculitis Decalvans (FD) can be seen in “tufting.” Tufting is a condition in which several hairs exit from the same hair follicle on the scalp skin. It may lead to an appearance of hair similar to the bristles of a toothbrush. Bald patches can eventually develop and increase in size, leaving permanent scarring hair loss. The medical term for this permanent hair loss through scarring is “cicatricial alopecia.”

How is Folliculitis Decalvans Diagnosed?

Diagnosis can generally be made by a dermatologist examining your skin, sometimes using a handheld magnifying light to look more closely at the hair follicles.

In some cases where additional confirmation is needed, some dermatologists may require a skin sample (skin biopsy) or a skin swab taken with a cotton wool bud to confirm the nature of the condition.

Treatment for Folliculitis Decalvans

There is currently no standard effective treatment for Folliculitis Decalvans.

Generally, Folliculitis Decalvans (FD) is treated with systemic antibiotics.

Other treatments may involve a combination of medicated shampoos, anti-inflammatory and antibacterial scalp, oral antibiotics, combinations of antibiotics, steroid injections, steroid creams, lotions, ointments, or more. Yet, most of these general treatments for Folliculitis Decalvans (FD) only offer a temporary, not permanent, solution to the problem.

Known as a relentless condition, treating Folliculitis Decalvans (FD) using the methods mentioned above may only lead to constant visits to the doctor or dermatologist for the patient, such as constant injections, which may not be the best solution for the patient’s overall health. Additionally, due to the relentless nature of this condition, untreated or improperly treated Folliculitis Decalvans (FD) using these methods mentioned above will eventually lead to a worsening of this condition and permanent hair loss.


Fortunately, there may be a permanent solution.

Dr. Sanusi Umar, AKA The Bumpinator, has developed a personalized approach to permanently eliminating Folliculitis Decalvans (FD).

Using his specialized procedures and inventions, he created such as his patented Athena Suture Kits, Dr. Sanusi Umar, AKA The Bumpinator, has been able to successfully eliminate Folliculitis Decalvans (FD) in several happy and satisfied patients using his combination of personal inventions and procedures, laser surgery, non-pharmaceutical botanicals, and in some rare cases, a combination of these elements along with radiation therapy.
