This study found that trichotillomania was more common in younger people, particularly females, and was characterized by increased catagen hair without perifollicular inflammation.

This article reviews the role of androgen in male pattern hair loss and its impact on hair follicle miniaturization, but it does not present new research findings.

This chapter describes the functions and purposes of hair care cosmetics, including shampoos, hair growth promoters, and grooming products, without reporting new experimental findings.

In this study, researchers observed that the sequence of maturity markers in normal boys showed specific time lags, with some markers appearing before and others after spermarche.

In this study, a 3-month treatment with a 2940 nm Er:YAG laser, combined with conventional therapy, effectively reduced microfibrosis around hair follicles and increased hair growth in the anagen stage among 85 men with androgenetic alopecia.

This article discusses the use of a high-magnification digital video microscope for diagnosing and treating androgenetic alopecia and reports no new clinical results.

The K15 promoter effectively targets stem cells in the hair follicle bulge.

This article presents a comprehensive guide for classifying human hair follicle cycle stages in vivo using scalp xenografts on immunocompromised mice, offering valuable resources for researchers in the field.

This study identified numerous genes that change expression across the anagen, catagen, and telogen stages of cashmere goat hair follicle development, highlighting key signaling pathways involved.

This article discusses the phases and histological features of alopecia areata and reports no new clinical findings; the authors emphasize recognizing these phases for accurate diagnosis.

This study found that proper levels of retinoic acid, controlled by the enzyme Cyp26b1, are essential for normal hair follicle development and morphogenesis in mice.

This study found that ICAM-1 expression in murine skin is developmentally regulated and crucial for skin and hair follicle remodeling beyond its recognized role in immune responses.

This study found that topical EGF-liposomal solution may protect hair follicles from chemotherapy-induced damage by inducing a catagen-like stage in a mouse model.

This study found that in alopecia areata, hair bulbs are blocked in an early growth stage due to impaired metabolic function in the surrounding connective tissue, hindering hair growth.

This study identified key mRNAs and lncRNAs, along with related pathways, that play potentially important roles in hair follicle development and cycling in cashmere goats.

This study found that injury affects the behavior of hair follicle dermal stem cells, steering them towards recruitment into the dermal papilla, a shift influenced by the hair cycle stage.

This study found that Hex gene expression patterns in chick embryo dorsal skin during feather bud development suggest a significant role in initiating feather morphogenesis.

This study observed that earlier-passage keratinocyte cultures led to superior hair follicle neogenesis in dermal-epidermal composites grafted onto immunodeficient mice, suggesting their potential utility in studying human hair follicle development.

This article discusses the use of cetuximab for recurrent squamous cell skin cancer in palliative care, noting good responses but frequent cutaneous side effects; it presents no new findings.

This study found that contrast enhanced phototrichogram (CE-PTG) significantly improved detection of various hair types and growth stages in androgenetic alopecia compared to standard PTG and was comparable to biopsy analysis.

This study investigated protein expression changes during mouse hair follicle cycles and suggested their involvement in biological networks, potentially identifying targets for hair disease therapy.

This study found that methylene blue staining helped identify late catagen and telogen hair follicles more accurately than unstained follicles, which suggests that established telogen percentage standards may be overestimated.

This review discusses the role of S100B protein in melanoma progression and its potential as a prognostic marker, reporting no new clinical findings; further studies are needed.

This study suggests that ADAM 10 and 12 proteases may play important roles in the regulation of hair cycling through their expression patterns in hair follicle structures.

This review discusses the scalp and follicular microbiome's potential role in hair diseases and the emerging interest in microbiome-targeted therapies, but reports no new clinical findings.

In this study, researchers reported that adenosine stimulated hair shaft elongation in cultured human hair follicles by promoting proliferation and prolonging the anagen phase, suggesting the A2B adenosine receptor in outer root sheath keratinocytes as a promising target for treating hair growth disorders like alopecia.

In their research, Yucel and colleagues found that CaV1.2 is expressed in hair follicle stem cells, facilitating anagen re-entry in a way not dependent on calcium flux.

Elderly patients have more severe hidradenitis suppurativa and may need different treatments.

This study suggests that D2O increases hair length in nude mice by extending the hair cycle duration, particularly the hair-existing phase, which is associated with increased mast cell density.

This study evaluated the safety and effectiveness of MNC-QQ cell therapy in five men with androgenic alopecia, reporting no adverse effects and improvements in hair growth, hair density, and quality of life over six months.
