This review discusses follicular and scarring disorders in skin of color and highlights the need for patient education and tailored therapeutic strategies, but does not report new clinical findings.

This study found that follicular streamers are mostly present in non-scarring alopecia cases, and tracking their location can improve diagnosis accuracy.

This study found that dense-packing megasession follicular unit extraction is a safe and effective method for treating extensive scarring alopecia, with a graft survival rate of 85% and high patient satisfaction.

This study found that certain C57BL/6 mouse substrains have a genetic vulnerability to skin lesions resembling central centrifugal cicatrical alopecia in humans, potentially worsened by high vitamin A levels.

This study found that follicular density and various hair growth ratios differ statistically between nonscarring and scarring alopecia, though significant overlap exists due to factors like sample size and scalp variation.

Combining FUE hair transplantation with PRP improves hair density and patient satisfaction in scarring alopecia.

In this cross-sectional study, both follicular lichen planus and discoid lupus erythematosus were identified as common causes of scarring alopecia, affecting young people with a more favorable prognosis for hair regrowth in discoid lupus erythematosus compared to follicular lichen planus.

In this study, treatment with autologous follicular stem cells improved hair conditions in 57% of patients with androgenic and telogen effluvium alopecia, as confirmed by phototrichograms, indicating its potential effectiveness for non-scarring alopecia.

In this study, follicular microautotransplantation was found to be an effective outpatient surgical treatment for scarring alopecia, with transplanted follicles showing an average engraftment rate of 93.8% and providing a good cosmetic outcome that improves patients' quality of life.

This study found that fibrosis-associated trochanters in central centrifugal cicatricial alopecia are enriched with hair follicle stem cells and may indicate a disrupted stem cell niche contributing to scarring.

This study reports that the asebia-2J mutation in mice affects sebaceous gland function and leads to hair follicle destruction, offering a model for human scarring alopecias.

Keratosis Pilaris Atrophicans causes skin scarring and might be treated with a new synthetic retinoid.

This article discusses the benefits, techniques, and unique considerations of follicular unit extraction for hair grafting, but reports no new clinical results.

This study demonstrates that sebaceous gland loss is a common early feature in primary scarring alopecia and suggests that inflammation of sebaceous glands or ducts may contribute to follicular damage.

This case study reports on a mother and daughter with ichthyosis follicularis, alopecia, and photophobia, noting consistent keratotic eruptions during the mother's pregnancies that improved postpartum.

This research analyzed 72 primary scarring alopecia cases in a Barcelona hospital, finding that the majority involved women, with a lymphocytic infiltrate and subacute onset in many cases, leading to stable disease, while neutrophilic cases had more acute episodes.

This case report describes a young Brazilian woman with scalp psoriasis that progressed to the rare complication of scarring alopecia.

This study found that the Elastic Verhoeff–Van Gieson stain may help differentiate between follicular streamers and scars in cicatricial and noncicatricial alopecias by highlighting differences in the elastic fiber network on horizontal scalp biopsy sections.

FUE can be successfully done on African-American hair by using larger punch tools and careful techniques to reduce hair damage.

This study reported that 80% of patients with non-scarring alopecia showed a clinical cure after treatment with unactivated platelet leukocyte autoplasma.

This narrative review suggests that exosome-based therapy shows promise for hair regeneration, offering improvements in hair density and thickness with favorable short-term safety in early clinical studies.

This review highlights niosomal cetirizine as a promising strategy for managing alopecia, potentially enhancing local bioavailability and reducing systemic exposure.

This study evaluated the therapeutic response of an Afro-descendant patient with non-scarring alopecia after prolonged use of alkaline straighteners and mechanical traction, highlighting the susceptibility of Afro hair to chemical and mechanical damage due to its structure.

This study examined molecular predictors of ritlecitinib efficacy in treating alopecia areata, highlighting the role of JAK3-dependent inflammation and follicular integrity as important factors in understanding disease mechanisms and potential therapeutic effectiveness.

This study found that ultraviolet-induced fluorescence dermoscopy enhanced the identification of follicular openings in alopecia areata, potentially aiding in the assessment of disease severity and treatment strategies.

This review addresses the causes, mechanisms, and treatment options for the most common non-scarring alopecias in females, including telogen effluvium, alopecia areata, and female pattern hair loss.

This study discusses the advantages and disadvantages of two hair graft harvesting methods, strip follicular unit transplantation and follicular unit excision, highlighting their implications for creating effective surgical plans for hair restoration without providing specific new results.

This case report describes a 39-year-old female with cutis verticis gyrata and cicatricial alopecia, emphasizing the need for further understanding of the potential genetic associations and underlying mechanisms.

This chapter reviews causes of poor scarring in hair restoration procedures and discusses methods for improving donor site scars, reporting no new clinical results.

In this study, researchers evaluated trichoscopy in diagnosing non-scarring alopecia and found diagnostic value in observing diverse hair diameters in androgenetic alopecia, black dots and broken hairs in alopecia areata, and empty follicles in telogen effluvium, supporting trichoscopy's utility in differentiating alopecia types.
