Background Central centrifugal cicatricial alopecia is the most common form of cicatricial alopecia in African American women. Treatment options are limited and mostly aimed at halting further hair loss but rarely result in hair regrowth. Therefore, it is important to recognize early clinical signs, perform a confirmatory biopsy, and begin treatment promptly. We have observed that hair breakage may be a key sign of early central centrifugal cicatricial alopecia, and this association is not clearly described in the literature.

Observations Nine patients with hair breakage on the vertex with or without scalp symptoms underwent scalp biopsies as part of their evaluation. Of these, 8 had histologic samples adequate for complete interpretation: 5 specimens (63%) showed histologic changes typical of central centrifugal cicatricial alopecia, with 1 of these showing advanced end-stage changes of cicatricial alopecia. Two (25%) revealed premature desquamation of the inner root sheath as the sole finding suggestive of early central centrifugal cicatricial alopecia and 1 (13%) was normal.

Conclusions Although hair breakage can have multiple causes, early central centrifugal cicatricial alopecia must be considered in the differential diagnosis, particularly in women of African ancestry. Histologic evaluation may reveal early or late findings that can help establish the diagnosis.

Central centrifugal cicatricial alopecia (CCCA) is a form of primary cicatricial alopecia that can result in the permanent destruction of hair follicles. It is the most common form of cicatricial hair loss among black women.1,2 Typically, CCCA presents on the vertex of the scalp and can be divided into early (inflammatory) and late (scarring) stages of disease.3 Although hair loss is permanent once the hair follicle is replaced with fibrous tissue, recognizing early stages of the disease and promptly initiating treatment may allow for hair regrowth and halt disease progression.3,4 We have observed that a subset of women with CCCA initially present with hair breakage localized to the vertex. This finding suggested to us that hair breakage may be an early indicator of CCCA. Therefore, we studied 9 African American women who presented with scalp symptoms and hair breakage but with no or minimal hair thinning and underwent scalp biopsy performed as a part of their evaluation for alopecia and/or scalp symptoms.


The medical records of 9 patients who presented with hair breakage with and without pruritus, erythema, and scalp tenderness were retrospectively reviewed. Hair breakage was identified as discrete zones of abnormally short hair compared with the surrounding hair. The short hairs showed frayed distal tips on microscopic or dermoscopic examination. Information about medical history, current medications, hair grooming practices, and physical examination was noted. Archived histologic slides of 4-mm scalp biopsy specimens from the periphery of the involved area, obtained after patient consent, were reviewed. Tissue was sectioned vertically and horizontally except for 1 specimen, which was only sectioned vertically because of laboratory error, although adequate histologic examination could be performed. In addition, 1 patient's biopsy sample could not be completely evaluated because of inadequate sections for complete histologic study and was therefore excluded from interpretation. This study was approved by the institutional review board of Schulman Associates Inc.

Table 1 presents the clinical information for the 9 patients. All patients were African American women with a mean (SD) age of 42.6 (5.8) years at initial presentation. Every woman had a history of chemical relaxer use. All but 1 patient had scalp symptoms, with the most common being pruritus in 7 patients (78%). Four patients (44%) had scalp tenderness. Three patients (33%) had evidence of localized vertex hair thinning but without obvious cicatricial hair loss. In 6 of the 9 patients (67%), the duration of disease was 8 months or less, with 1 patient presenting only 3 months after the start of symptoms. On examination, hair breakage occurred proximally on the hair shaft (0.5-2 cm from the scalp) in patches localized to the vertex (Figure 1 and Figure 2).

Of the 8 biopsy specimens completely evaluated, 5 (63%) demonstrated histologic changes typical of CCCA, but with varying degrees of severity. One showed more advanced end-stage changes of cicatricial alopecia with destruction of most of the follicles. Another demonstrated premature desquamation of the inner root sheath (PDIRS) and lamellar fibroplasia with perifollicular inflammation but had no evidence of follicular destruction (Figure 3 and Figure 4). The remaining 3 biopsy specimens showed the full complement of histologic findings typical of CCCA (Figure 5), including focal follicular destruction.

The sole abnormality found in biopsy specimens from 2 patients (25%) was PDIRS; otherwise, the findings on these scalp specimens were normal. Only 1 patient had completely normal biopsy results (13%), and biopsy was performed again 1 year later.

All patients were empirically prescribed high-potency topical corticosteroid foam or ointment nightly and corticosteroid shampoo weekly at the first visit. After biopsy results were obtained, patients received intralesional triamcinolone, 5 mg/mL every 4 to 6 weeks for approximately 1 to 3 sessions. Additional treatments varied based on the patient's clinical presentation, symptoms, and physician preference and included ciclopirox shampoo, zinc pyrithione shampoo, doxycycline hyclate, midpotency topical corticosteroid, minoxidil (2%-5%), and/or sulfur–salicylic acid–corticosteroid compound. As indicated in Table 1, 4 patients (44%) experienced hair regrowth, 1 patient's (11%) hair loss progressed, and 4 patients (44%) were lost to follow up.


LoPresti et al5 first described CCCA as “hot comb alopecia” in 1968, when this type of scarring alopecia was thought to result from the hot liquefied petrolatum created by hot pressing comb use. The theory was that hot pressing oil descended into the follicle, causing chronic inflammation around the upper segment of the hair. Eventually, the external root sheath degenerated with subsequent destruction of the hair follicle and replacement with dense fibrous tissue.5

The cause of scarring alopecia by hot combing has subsequently been debated.1,6,7 Although the use of hot combs has significantly decreased over the years, the prevalence of scarring alopecia among black women has not seen a corresponding decrease.1 In 1992, Sperling and Sau6 performed a retrospective study on 10 women thought to have hot comb alopecia, but most did not have a significant history of hot comb use. Because of the poor correlation of hot comb use and onset and progression of the disease in these patients, the authors concluded that the use of hot combs may contribute to follicular damage only among women who may be predisposed to follicular damage but was not the single cause of this type of scarring alopecia. The term follicular degeneration syndrome replaced hot comb alopecia based on characteristic histologic findings.1 However, in 2001, the North American Hair Research Society–sponsored Workshop on Cicatricial Alopecia recommended use of the current term CCCA, which was intended to be more descriptive and encompass prior terms, such as follicular degeneration syndrome, hot comb alopecia, and pseudopelade, in African Americans.8 Despite this descriptive term, CCCA remains an incompletely understood inflammatory process that can result in permanent hair loss involving much of the scalp.

Histologically, CCCA demonstrates varying levels of inflammation, ranging from minimal to intense perifollicular lymphohistiocytic infiltration involving the infundibulum and isthmus, typically leading to replacement of terminal hair follicles with fibrous tracts.9 In addition, PDIRS is observed, followed by eccentric atrophy of the outer root sheath epithelium, concentric lamellar fibroplasia, and subsequent hair granulomas.2,6,10 Residual arrector pili muscles may remain within the resulting dense fibrosis.10 Lamellar fibroplasia, PDIRS, and perifollicular inflammation are typical findings of CCCA. However, the presence of PDIRS in an otherwise histologically normal scalp specimen is highly suggestive of early CCCA, unlike other forms of scarring alopecia, where PDIRS is only associated with well-established, severe inflammation.11 This particular finding is important in the pathogenesis of disease because it may predispose the affected follicles to external injury.12

On clinical examination, erythema and scaling may indicate the presence of inflammation around hair follicles, and at any stage of the disease, patients may experience pruritus and/or scalp tenderness.9 Our cases reveal that most patients experienced pruritus (78%) and scalp tenderness (44%). Early in the disease, the scalp may appear normal or exhibit hair breakage or decreased hair density in an area measuring only a few centimeters in diameter.12 However, it may be difficult to obtain an accurate duration of symptoms due to the insidious onset and slow progression of CCCA in many patients. Hair loss or breakage may be present for years before the patient notices the hair loss.6 The location of hair breakage, particularly on the vertex, may also make it difficult for patients to notice the onset of hair loss. In fact, Gathers et al7 found that 51 study patients with CCCA (21%) were first informed of their hair loss by a hairstylist. Most of our patients (67%) had symptoms for 8 months or less. One patient reported symptoms for only 3 months, but her biopsy specimen revealed advanced CCCA, which may be due to the long-term presence of relatively asymptomatic CCCA, unnoticed by the patient until the onset of more severe scalp symptoms or hair breakage.

Hair breakage in our patients occurred in a well-demarcated area of the vertex with normal to decreased hair density and minimal to no clinical evidence of scarring. However, in most of our study patients, biopsies revealed a histologic spectrum of findings typical of CCCA. Hair breakage has not been previously reported as a common early clinical finding of CCCA but rather is usually associated with hair care products and practices, systemic diseases, or various scalp disorders (Table 2). In general, women of African descent may be particularly susceptible to hair breakage given the innate fragility of the hair shaft in this population.13,14 In normal hair development, the cells of the inner root sheath (IRS) cornify before the central hair cortex that will form the hair shaft; thus, the IRS provides a rigid cylinder by which the developing hair shaft is molded and guided outward.1,15 It is unclear why some patients with early CCCA develop hair breakage, but one could postulate that the lack of a complete IRS leads to disorderly packaging of the hair shaft, particularly the cuticle, causing instability and ultimately breakage. However, this theory would not explain why biopsy specimens from areas of hair breakage in these patients show follicles with intact IRS as well.

Whether chemical relaxers or styling with excessive heat causes CCCA remains to be determined; however, it is clear that these hair grooming practices can injure the hair shaft.1618 A population study by Kyei et al19 found that patients with CCCA had a significant increase in the use of traction hairstyles (eg, braids and weaves), which can cause scalp folliculitis, than patients with less severe central hair loss. Thus, the difficulty in attributing hair breakage to early CCCA alone lies in determining the true causative factors because most of the women who develop CCCA also use traumatic hair care practices. On the other hand, not all women who use these traumatic hair care practices develop CCCA. Chemical relaxers, permanents, hair dyes, and heat styling can damage and weaken the hair shaft, whereas certain styling products, such as gels and hair sprays, lead to increased dryness and difficultly manipulating the hair, causing breakage.13,14,2022 However, in this study, hair breakage was localized to the exact areas of the scalp normally affected by CCCA, and the presence of CCCA was confirmed by biopsy in most of our cases. Chemical relaxers and permanents, on the other hand, are typically applied to the hair diffusely, and known chemically induced hair breakage is not solely limited to the vertex and often occurs in the anterior or posterior hairline or as several patchy areas on the scalp.23 More clinical studies are needed to determine the mechanism of follicular abnormalities present in CCCA, which lead to hair shaft damage, and whether traumatic hair care practices also contribute to the development of this finding.

Early recognition and treatment of CCCA may halt further progression of the inflammatory and destructive process. Table 3 lists the clinical evaluation that should be performed on patients whose clinical picture may be suggestive of early CCCA but have not yet manifested the characteristic signs of the disease. Physicians must maintain a high index of suspicion even in younger patients. In the study by Gathers et al,7 more than 20% of patients with CCCA noticed some hair thinning or balding by 30 years of age. When CCCA is suspected, the diagnosis can most often be confirmed by biopsy. In our study, 5 of 8 patients (63%) with hair breakage in the vertex had histologic changes consistent with CCCA. In the 1 patient with a normal biopsy result, the clinical history and examination were suggestive of CCCA, and the negative result may be attributable to sampling error. Patients 8 and 9 showed a few follicles with PDIRS on histologic examination, which demonstrates the utility of confirmatory biopsy, especially in early disease, and further supports the concept that PDIRS may be the earliest pathologic finding in CCCA. In our cases, we did not find a correlation between duration of disease and severity of histologic inflammation. However, there may be sampling error because only a small portion of a much larger involved area is obtained with a 4-mm punch biopsy. Also, the number of patients in this study is too small to establish the presence or absence of any correlation with confidence.

Although 8 of 9 patients had scalp symptoms and 3 had localized hair thinning of the vertex (without evidence of scarring), hair breakage appeared to be the most dependable clue to the underlying diagnosis of CCCA. The symptoms could be attributed to seborrheic dermatitis and the thinning to androgenetic alopecia. Therefore, the physician has to consider a more serious problem and perform a diagnostic biopsy.

In summary, we have shown that it is important for physicians to include early CCCA in the differential diagnosis of hair breakage in the crown or vertex even in the absence of obvious scarring alopecia, particularly in patients of African ancestry. Simply advising patients to alter hairstyling habits is not sufficient and may prove to be ineffective. Early initiation of medical treatment will give these patients the greatest chance for halting disease progression and regrowing hair.
