This case report describes successful hair regrowth after removing a nevus in a patient with perinevoid alopecia and concentric regrowth, which are rare patterns of alopecia areata.

This study concludes that elastic tissue staining is the most reliable method for identifying scarring patterns in alopecia biopsy specimens, and polarized microscopy may provide specific insights for nonscarring alopecia.

The study found that pili bifurcati causes hair to intermittently split into two branches, each with its own outer layer.

This article discusses the uses and techniques of trichoscopy for hair and scalp disorders and reports no new clinical results.

This article proposes a classification for small graft transplants that includes technical factors to improve communication and facilitate comparative studies, reporting no new clinical results.

In this observational study, dermoscopy was found to be a useful tool in diagnosing lichen planopilaris among patients with primary cicatricial alopecia.

This letter argues that cicatricial pattern hair loss likely represents end-stage androgenetic alopecia and not a variant of lichen planopilaris, as previously suggested.

In this study, trichoscopy revealed hair shaft abnormalities similar to those seen in alopecia areata and chemotherapy-induced alopecia in patients over 12 months following hair restoration surgery.

This case report identifies a new type of hair matrix tumor called "rippled pattern trichomatricoma," distinguished by its unique cell arrangement and differentiation features.

Ludwig pattern hair loss results from varying androgen sensitivity, causing fewer thick hairs and more thin hairs.

This study found that dermoscopy combined with calcium fluorescent white staining effectively aided in the early diagnosis and treatment evaluation of tinea capitis by highlighting specific hair changes and fluorescent patterns associated with different dermatophyte infections in a sample of 20 patients.

This study observed that specific trichoscopic features like white peripilar signs, scalp pigmentation, and focal atrichia are associated with advanced female pattern hair loss in Fitzpatrick skin type III patients.

This study found significant differences in facial heat distribution patterns among different types of alopecia, with androgenic, areata, and telogen types showing a T-type pattern, while seborrheic alopecia showed a diffused pattern.

In this study, trichoscopic features aiding differential diagnosis of alopecia in Korean patients were found to be similar to those in Caucasians, but pigment pattern frequencies differed due to racial characteristics.

This study observed that the keratinization pattern of trichilemmal cysts in two Japanese women may originate from the proliferation of the outer root sheath in the follicular isthmus of anagen hairs.

In this study, the authors compared trichoscopy findings for different forms of diffuse non-cicatricial alopecia in females and suggested that trichoscopy might often replace the need for histopathological confirmation, reserving biopsies for more uncertain cases.

This study compared trichostasis spinulosa with keratosis pilaris and eruptive vellus hair cysts, finding differences in lesion distribution and microscopic appearance.

This article presents a comprehensive overview of hair microscopy techniques and their diagnostic potential for systemic and cutaneous disorders, emphasizing its usefulness in resource-limited settings and highlighting the underutilization of this non-invasive method due to lack of awareness.

In this hospital-based cross-sectional study, researchers found that alopecia is more prevalent in younger patients, with alopecia areata and lichen planopilaris being the most common types among noncicatricial and cicatricial cases, respectively; additionally, thyroid abnormalities were frequently associated with both types of alopecia.

This study introduced the BASP classification, a new system for categorizing pattern hair loss in both men and women, and applied it to analyze 2213 Korean subjects.

This article discusses distinguishing features of Diffuse Alopecia Areata and Fibrosing Alopecia in a Pattern Distribution, but reports no new clinical results.

This review discusses female pattern hair loss as distinct from androgenetic alopecia and suggests that clinicians use tools like dermoscopy and histopathology for more accurate diagnosis, without reporting new findings.

This study aimed to identify trichoscopic features that help differentiate between tinea capitis and alopecia areata in children, enhancing diagnosis and treatment decisions visually and non-invasively.

This article reviews the use of trichoscopy for differentiating mimickers of patterned hair loss and assessing donor sites in hair transplant patients, without providing new clinical findings.

This review discusses the evolution of the term “hot comb alopecia” to central cicatricial centrifugal alopecia (CCCA) and highlights the ongoing debate over hairstyling practices' role in its pathology, without offering new clinical results.

This pilot study found that examining changes in scalp scales after scraping may effectively distinguish seborrheic dermatitis associated with androgenetic alopecia from fibrosing alopecia in a pattern distribution.

In this study, LC-OCT was used to distinguish between subtypes of scarring alopecia, laying the groundwork for further hypotheses and future research in larger and longitudinal studies to examine treatment responses.

This study found that while a modified BASP classification for pattern hair loss could classify previously unrecognized types, it was less accurate and harder to use than the existing BASP classification.

This report details two cases of alopecia areata with unusual annular and circinate patterns, highlighting atypical morphology of the condition.
