Definition

Folliculitis keloidalis (FK) is a chronic inflammatory condition that affects the hair follicles on the back of the neck and scalp. It is characterized by the formation of keloid-like scars, which can be itchy, painful, and unsightly. Folliculitis keloidalis (FK) is a chronic condition characterized by the formation of small, raised bumps or keloids on the back of the neck, scalp, or other areas where hair grows. The exact cause of FK is not known, but it is believed to be related to irritation and inflammation of the hair follicles.

Causes

The exact cause of FK is unknown, but it is thought to be related to a combination of factors, including:

Genetics: FK tends to run in families and is more common in people of African descent.
Trauma: Constant friction or irritation of the hair follicles, such as from tight hairstyles or clothing, may contribute to the development of FK.
Bacterial infection: Folliculitis caused by bacteria such as Staphylococcus aureus may lead to the formation of keloid-like scars.

Symptoms

Small, red bumps around hair follicles
Itchy, painful skin
Keloid-like scars, which can be raised and have a shiny appearance
Pus-filled bumps or boils
Hair loss in the affected area

It is important to consult a dermatologist for proper diagnosis and treatment. Treatment options may include topical or oral antibiotics, topical or intralesional steroid injection, laser therapy and surgery.

Diagnosis

FK is typically diagnosed based on a physical examination of the affected area. A skin biopsy may be performed to confirm the diagnosis and rule out other conditions.

Treatment

Treatment for FK may include:

Topical medications: Topical creams, lotions, or ointments containing steroids or antibiotics may be used to reduce inflammation and itching.
Oral medications: Oral antibiotics or corticosteroids may be prescribed to help control the inflammation.
Laser therapy: Laser therapy can be used to reduce the size of the keloids and improve the appearance of the affected area.
Surgery: In some cases, surgery may be necessary to remove the keloids.
Preventive measures: Keeping the affected area clean and avoiding tight hairstyles or friction can help prevent further irritation.

It is important to consult with a dermatologist for an accurate diagnosis and personalized treatment plan, as FK can be difficult to manage and may require a combination of treatments to achieve the best results.

Safety note: This is not a prescription or diagnosis. For severe symptoms, pregnancy danger signs, children with serious illness, chest pain, breathing difficulty, stroke-like weakness, or major injury, seek urgent care.

Which doctor may help?

Start with a registered doctor or the nearest qualified health center.

What to tell the doctor

Write when the problem started and how it changed.
Bring old prescriptions, investigation reports, and current medicines.
Write allergies, pregnancy status, diabetes, kidney/liver disease, and major past illnesses.
Bring one family member if the patient is weak, elderly, confused, or a child.

Questions to ask

What is the most likely cause of my symptoms?
Which danger signs mean I should go to hospital quickly?
Which tests are necessary now, and which can wait?
How should I take medicines safely and what side effects should I watch for?
When should I come for follow-up?

Tests to discuss

Vital signs: temperature, pulse, blood pressure, oxygen saturation
Basic physical examination by a clinician
CBC, urine test, blood sugar, or imaging only when clinically needed

Avoid these mistakes

Do not use antibiotics, steroid tablets/injections, or strong painkillers without proper medical advice.
Do not hide pregnancy, kidney disease, ulcer, allergy, or blood thinner use.
Do not delay emergency care when danger signs are present.

Safe first steps

Rest, drink safe water, and observe symptoms carefully.
Keep a written note of symptoms, duration, temperature, medicines already taken, and allergy history.

For rural patients and family caregivers

Patient health record and symptom diary

Write your symptoms, medicines already taken, test results, and questions before visiting a doctor. This note stays on your device unless you print or copy it.

Doctor to discuss: Doctor / qualified healthcare provider

Tests to discuss with doctor

Relevant blood, urine, imaging, or specialist tests only after clinical assessment

Questions to ask

What is the most likely cause of my symptoms?
Which warning signs mean I should go to emergency care?
Which tests are really needed now?
Which medicines are safe for my age, pregnancy status, allergy, kidney/liver/stomach condition, and current medicines?

Emergency warning signs such as chest pain, severe breathing difficulty, sudden weakness, confusion, severe dehydration, major injury, or loss of bladder/bowel control need urgent medical care. Do not wait for online information.

Go to emergency care if you notice:

Severe or rapidly worsening symptoms
Breathing difficulty, chest pain, fainting, confusion, severe weakness, major injury, or severe dehydration

Doctor / service to discuss: Qualified healthcare provider; specialist depends on symptoms and examination.

Step 1
Check danger signs first

If danger signs are present, seek emergency care and do not wait for online information.
Step 2
Record the symptom story

Write when symptoms started, severity, medicines already taken, allergies, pregnancy status, and test results.
Step 3
Visit a qualified clinician

A doctor, nurse, or qualified healthcare provider can examine you and decide which tests or treatment are needed.
Step 4
Do only useful tests

Do tests after clinical assessment. Avoid unnecessary tests, random antibiotics, or repeated medicines without diagnosis.
Step 5
Follow up and return early if worse

If symptoms worsen, new warning signs appear, or treatment is not helping, return for review quickly.

Rural patient practical tips

Take a written symptom diary and all previous prescriptions/test reports.
Do not hide medicines already taken, even herbal or over-the-counter medicines.
Ask which warning signs mean urgent referral to hospital.
