This study found that intra-follicular Wnt signaling and dermal BMP signaling oscillate differently during hair cycling in mice, affecting hair wave propagation and phases of hair growth.

This review discusses the role of tissue mechanics and extracellular matrix in skin aging processes and highlights potential therapeutic strategies, but reports no new clinical results.

This study found that a novel 15% topical minoxidil solution achieved a clinically significant hair regrowth response in 60% of women with female pattern hair loss who did not respond to 5% minoxidil, without increasing adverse events.

This study reports a new optimized protocol for isolating and labeling single cells from neonatal mouse skin, enabling high-quality single cell RNA sequencing for lineage-specific cell analysis.

This study found that hair follicle matrix progenitors differentiate into various layers asynchronously, with early progenitors forming the companion layer and later progenitors generating the inner root sheath and hair shaft.

In this pilot study, researchers observed a correlation between clinical severity and histologic severity of lichen planopilaris, suggesting that an immunohistochemical scoring system could aid in grading disease activity.

This study shows that differences in Hoxc gene expression in hair follicle mesenchyme along the body axis contribute to regional variations in mammalian hair growth.

Hormones and genetics play key roles in male and female baldness, which can affect mental health and may be linked to other health issues.

A 19-year-old male with delayed puberty was successfully treated for a condition that prevents normal hormone production.

This review explores recent findings on the roles of melanocyte and melanocyte stem cells in the hair follicle, highlighting their importance for skin health and potential applications in regenerative medicine, but reports no new clinical results.

This study identified distinct gene expression programs in keratinocytes responsible for forming hard scales and soft interscale epidermis in chickens, revealing conserved differentiation genes similar to those in human skin.

This study suggests that hormone replacement therapy and oral contraception may have a protective role in scarring alopecia, as these were reported less frequently by patients with the condition compared to those with female pattern hair loss.

This review examines recent advances in understanding the pathophysiology and molecular mechanisms of androgenetic alopecia, highlighting two major genetic risk loci, but does not report new clinical findings.

This article reviews recent advancements in understanding skin stem cells and their roles in maintaining epidermal homeostasis and repairing wounds, without presenting new experimental findings.

In this study, four women with chronic telogen effluvium experienced fluctuating hair shedding without visible reduction in hair density or follicular miniaturization over at least 7 years.

This review discusses the interactions between melanocyte stem cells and their niche in hair regeneration and repair, but reports no new results; recent studies on molecular pathways are highlighted.

Tigason improved hair growth in a boy with monilethrix without side effects.

Finasteride caused blisters on hands and feet.

This study described specific skin and hair follicle abnormalities in three Japanese patients with Cantu syndrome, which may relate to the regulation role of SUR2 in hair follicle growth.

This case report describes a 40-year-old man whose vitiligo and psoriasis responded favorably to ixekizumab after experiencing vitiligo onset and psoriasis relapse during adalimumab treatment.

In this case report, a 45-year-old Jordanian woman was diagnosed with Clouston syndrome, an autosomal-dominant disorder characterized by alopecia and nail dystrophy due to a mutation in the GJB6 gene, though she lacked the typical palmoplantar keratoderma.

Modern hair restoration techniques can effectively treat hair loss and provide natural-looking results.

This study found that hair from mice with the Naked trait mutation has significantly lower levels of glycine and tyrosine, suggesting a deficiency in a specific protein fraction.

This study found that polycomb-group-mediated repression plays a key role in regulating hair follicle stem cell states and lineage progression by distinct mechanisms in adult mouse skin.

This study observed that epidermal growth factor and fibroblast growth factor have distinct roles in sheep skin, with EGF involved in differentiation and FGF in bulb proliferation and fiber growth.

In this study involving adult mice, the researchers identified that double-stranded RNA-mediated activation of toll-like receptor 3 stimulates wound-induced hair neogenesis, potentially reflecting mechanisms used in facial rejuvenation treatments.

Activating the Eda/Edar pathway improves wound healing by enhancing hair follicle growth.

This study found that the BMP antagonist noggin induces hair growth in postnatal skin by neutralizing BMP4's inhibitory activity, potentially mediated by changes in Shh expression.
