This series has covered androgenetic alopecia, alopecia ariata, telogen afluvium, traction alopecia, and postpartum shedding. Today's article covers a condition that affects a significant population and receives far less attention than those better known types: Central Centrifugal Cicatricial alopecia, CCCA. CCCA is a distinctive form of scarring alopecia characterized by patches of permanent hair loss that manifest on the vertex or crown of the scalp, progressively spreading outward in a centrifugal pattern. It is predominantly observed in women of African descent, displaying a familial predisposition. CCCA affects 2.7-5.7% of black women and is the most common form of scarring alopecia in this population. It causes progressive, permanent follicle destruction. And a February 2026 study from UCLA published in the Journal of Drugs and Dermatology found something that makes both of those facts more urgent. CCCCA is associated with longer time to diagnosis than any other scarring alopecia. A documented health disparity that directly affects outcomes. The reason early diagnosis matters so much is straightforward. Scarred follicles cannot be restored. Progression can be slowed with treatment. Destroyed follicles cannot be recovered. The gap between when CCCA begins and when it is correctly identified and treated is the gap in which permanent follicle loss accumulates. What CCCA is the mechanism and why it is different from every other hair loss type in this series, CCCA is a scarring alopecia, meaning the inflammatory process destroys the hair follicle and replaces it with fibrous scar tissue. This places it in a fundamentally different category from Agea, follicle miniaturization, alopecia ariata, autoimmune attack on an intact follicle, telogenofluvium, temporary disruption of cycling, and traction alopecia, mechanical stress. In all of those conditions, the follicle is damaged but potentially recoverable. In CCCCA, once the follicle is replaced by scar tissue, it is gone. Histology of CCCA reveals parapolicular lymphocytic inflammation of the lower infantibulum, premature desquamation of the inner root sheath, and fibrous connective tissue replacing the follicular structure. The premature desquimation of the inner root sheath is considered a hallmark feature. It is the earliest detectable change and represents the starting point of the inflammatory cascade that eventually destroys the follicle. A genetic susceptibility has been identified in approximately one-third of women studied. Loss of function variants affecting the enzyme PATI3, which modifies proteins involved in hair growth. This genetic factor, inherited in an autosomal dominant pattern in some families, means CCCCA runs in families, and a family history of the condition is a meaningful risk flag. What to watch? For the earliest signs, and why they are regularly missed. CCCA typically begins at the crown or vertex of the scalp and progresses outward in a circular pattern, which is where the centrifugal in its name comes from. The earliest signs are often subtle and easily attributed to other causes. Scalp tenderness, itching, or burning at the crown symptoms, including scalp pain, tenderness, itching, or a burning sensation at the crown, are often the first subjective signs of active CCCA inflammation. These symptoms precede visible hair loss in many cases, which means they represent the window where intervention can preserve follicles that have not yet been destroyed. These symptoms are frequently attributed to product sensitivity, tight styling, or sebarric dermatitis rather than triggering evaluation for scarring alopecia. Smooth, shiny scalp areas at the crown. As CCCA progresses, the affected area develops a smooth, shiny appearance. The visual sign of scar tissue replacing the normal scalp surface. The hair follicle openings, ostia, disappear. This is the sign that indicates active fibrosis has occurred and follicles in that area have been permanently destroyed. Trichoscopy, a dermoscope at 10X magnification, reveals the absence of follicular openings and the characteristic features of scarring alopecia. This is one reason trichoscopy by a dermatologist or tricologist familiar with CCCA is essential for correct diagnosis. Crown-centered pattern progressing outward, the centrifugal spread from crown outward distinguishes CCCA from AGA, which also affects the crown but presents with miniaturization rather than scarring, and from traction alopecia, which affects the hairline and edges. The combination of crown-centered onset, symmetric outward progression, and the scalp changes described above in a black woman with a family history, is a clinical picture that warrants immediate dermatological evaluation, not watchful waiting. 2.7-5.7% prevalence in black women, making CCCA the most common scarring alopecia in this population and one of the most underrecognized conditions in hair medicine. Longest CCCA has the longest time to diagnosis of any scarring alopecia. 2026 UCLA study confirmed this as a documented health disparity with direct consequences for outcomes 1 in 3 CCCA patients carry PD, 3 loss of function variants, making family history a meaningful risk factor that should inform screening in relatives of affected women treatment, honest about the limits. What exists, what helps, and what doesn't yet. Despite its high prevalence, CCCA remains understudied. Patients with CCCA were significantly less likely to report improvement following treatment compared to controls with non-CCCA scarring alopecia. The May 2025 Mayo Clinic Case Control Study of 54 biopsy-confirmed CCCA patients confirmed this. The treatment response is more limited than for other scarring alopecias. Current treatment modalities, topical and systemic corticosteroids, oral tetracyclines, hydroxychloroquine, aim to reduce inflammation and slow progression rather than reverse damage. Treatment options for CCA remain.
