Advances in Hair Diseases

This article reviews major types of genetic hair shaft defects and associated syndromes, emphasizing understanding histologic features and diagnostic methods, but reports no new clinical findings.

This review of interventions for alopecia areata found no significant treatment benefits for hair growth compared to placebo, indicating a need for larger, well-conducted studies.

This review discusses hair keratins and hair follicle-specific epithelial keratins and their association with inherited hair disorders, reporting no new clinical results.

This study identified four genetic loci on chromosomes 6, 10, 16, and 18 that may contribute to susceptibility for alopecia areata and suggested shared genetic factors with psoriasis.

This review discusses the complexities of diagnosing and treating iron deficiency related to nutritional anemia and hair loss, concluding that routine screening and supplementation for hair loss are not yet supported by sufficient evidence.

This study suggests that hair follicle stem cells from transgenic mice can improve nerve regeneration and function, highlighting their potential as an autologous source for regenerative medicine.

This study describes a system for generating hair follicles from dissociated cells in mice, suggesting that successful development requires a foundational epithelial platform.

This article reviews the historical developments in understanding and treating male pattern hair loss, emphasizing the role of dihydrotestosterone and 5α-reductase inhibitors, but reports no new clinical findings.

This study found that dermal papilla and peribulbar dermal sheath cup cells in mice can both induce hair follicle formation, suggesting they may have similar functional roles in hair growth.

This study found that a keratin mutation may cause diffuse partial woolly hair associated with loose anagen hair syndrome in some families, but other genetic factors could play a role in different cases.

This study describes the kenogen phase, where hair follicles rest after shedding, and finds its duration and frequency are greater in individuals with androgenetic alopecia, potentially contributing to baldness.

This case report describes a patient with mutations in both alleles of the vitamin D receptor who exhibited hair loss clinically indistinguishable from generalized atrichia with papules, suggesting a potential genetic pathway shared with the hairless gene.

This review discusses common hair loss conditions and explores how advancements in hair follicle biology might lead to more effective treatments but reports no new results.

In this study, finasteride 1 mg/day for 12 months did not improve hair growth or slow hair thinning in postmenopausal women with androgenetic alopecia compared to placebo.

This article discusses the etiology, clinical features, diagnosis, histopathology, and treatment of alopecia areata but reports no new clinical findings; it emphasizes the palliative nature of current treatments.

This article highlights a specific, yet largely unrecognized, sign that aids in diagnosing androgenetic alopecia in women, emphasizing its practical application in clinical settings.

In male pattern hair loss, this study found that finasteride 1 mg daily significantly slowed hair loss and increased hair growth over two years compared to placebo.

This study identified a missense mutation in the human hairless gene associated with a rare form of recessively inherited alopecia universalis, pinpointed on chromosome 8p12.

This article proposes five mechanisms for telogen effluvium based on changes in the follicular cycle, which are supported by clinical findings, highlighting the condition's diverse causes.

This article reviews the classification of hair shaft abnormalities, outlining their diagnostic features, but does not present new research findings.
