What is central centrifugal cicatricial alopecia?

💡 まず結論

A shiny, slowly expanding bald patch on the vertex is not “just traction from a ponytail” until a clinician says so. Scarring means follicles can be permanently lost.

Central centrifugal cicatricial alopecia (CCCA) is a primary scarring (cicatricial) alopecia. The American Academy of Dermatology and hair-loss specialists describe it most often in women of African descent, beginning at the crown and moving centrifugally. Symptoms can include tenderness, itching, burning, or surprisingly little discomfort. The scalp may look smooth and shiny where follicles are destroyed. Hot-comb and chemical-relaxer history was discussed for decades; current thinking treats CCCA as a follicular disease in which styling can still add insult. This is not medical advice and not a racial stereotype — it is an epidemiology pattern that should speed referral, not delay it.

Diagnosis often needs a scalp exam and sometimes a biopsy. Treatments dermatologists use can include anti-inflammatory medicines; this page will not name a milligram or a steroid class as a home kit. Minoxidil may support remaining hairs. Stopping tight weaves, braids, and harsh chemicals is usual counseling. Early care matters because scarred skin does not grow a full density photo.

Do not confuse CCCA with a round alopecia areata patch (often non-scarring, sudden) or with ordinary female-pattern widening of the part without shine. Frontal fibrosing alopecia starts at the front, not the crown-outward pattern. If the crown is tender and shiny, skip the next tight style and book dermatology.

よくある質問

Is CCCA the same as traction alopecia?

They can overlap in the same person. CCCA is a scarring disease of the follicle. Traction is mechanical pull. A dermatologist separates them.

Can hair grow back in the shiny area?

Scarred follicles usually cannot fully return. The goal is to stop spread and protect remaining hair. Early treatment matters.

Should I stop braids and weaves?

Many clinicians advise reducing tension and harsh chemicals. That is not a moral judgment on protective styles; it is wound-care for a scarring scalp. Ask your dermatologist what is safe for you.

Can minoxidil reverse the shiny patch?

Minoxidil cannot rebuild destroyed scarred follicles. It may support remaining hair after a clinician maps the area. Do not delay dermatology for a foam experiment.
