Deuruxolitinib significantly improves hair satisfaction in severe alopecia areata patients.

This observational study reports that a TRASER device using specific wavelengths for vascular and follicular targets showed both clinical responses and histological changes, suggesting its potential as an effective vascular and hair removal tool.

This study found that a high dose of epidermal growth factor induced hair loss in sheep by causing apoptosis in anagen hair and transitioning the hair cycle to catagen.

This study found that the Spanish version of the hair-specific Skindex-29 questionnaire effectively detected changes in health-related quality of life among women with female-pattern hair loss, and the scores were significantly correlated with the SF-12 survey results after treatment with a 5 alpha-reductase inhibitor.

3D ultrasound can detect hair follicle changes and disease phases in alopecia areata.

This study utilized 3D ultra-high frequency ultrasound to effectively detect different disease phases of alopecia areata by visualizing hair follicle structures and identifying unique pathological signs, offering a promising non-invasive diagnostic tool that surpasses conventional methods.

This review discusses the physiological skin changes during pregnancy and reports no new clinical results, emphasizing the importance of distinguishing these changes from pathological conditions.

This review provides an overview of the physiologic skin changes during pregnancy but reports no new findings, emphasizing the need for physicians to distinguish between benign and potentially pathological conditions.

In this study, changes in hair cycle phases during pregnancy and the post-partum period showed a rise in telogen rates after delivery, especially among non-breastfeeding women, but no drastic exaggerations were noted.

This study observed that rat vibrissa hair follicles cultured in vitro showed morphological changes suggesting cyclical activity but remained blocked in the pro-anagen stage.

This phase I study determined that a combination of oral SU-014813 and docetaxel is a feasible treatment with a manageable safety profile and potential anti-tumor activity, particularly noted in melanoma and GIST patients.

This study identified three symptom trajectory groups in individuals with PMDD, highlighting variations in symptom severity and duration across the luteal and follicular phases.

This article reviews the skin changes that can occur with hormonal contraceptive use and highlights various mechanisms and potential treatment strategies but reports no new clinical results.

In this animal study, Hirudo verbana leech extract significantly improved hair follicle regeneration and accelerated wound healing in rats, demonstrating potential as a safe and effective agent for skin repair due to its bioactive compounds with regenerative and anti-inflammatory properties.

This study examined prenatal and postnatal development of rat skin, observing marked changes in epidermal thickness and collagen fiber distribution as the rats aged.

In this study, researchers found that changes in the extracellular matrix components, particularly fibronectin, laminin, and type IV collagen, during the rat vibrissa follicle growth cycle, suggest dynamic remodeling related to dermal-epidermal signaling.

This study suggests that different melanocyte subpopulations in hair follicles have varying patterns of apoptosis and survival during the catagen phase, which may inform models for modulating melanocyte behavior in vivo.

This study reported that etretinate treatment leads to increased hair shedding due to a sustained decrease in anagen duration, with an arrest at the onset of anagen and a follicular anchorage defect in telogen contributing to alopecia.

In this study, mini rats with reduced growth hormone and insulin-like growth factor-1 levels exhibited distinct differences in skin thickness and hair cycle compared to standard Wistar rats, suggesting potential use as an animal model for studying GH deficiency-related skin conditions.

This study found that, in Japanese patients with androgenic alopecia, sebaceous glands exhibit increased multilobulation which may be significant in the condition's pathology.

This study found that mycophenolate may stabilize β-catenin and counteract interferon-γ-induced catagen changes in human dermal papilla cells, which could promote hair growth.

This study found that IPL hair reduction led to significant decreases in hair count and thickness by promoting hair follicle miniaturization, increased telogen phase, and reduced cell proliferation.

In this study using C57BL/6N mice, the researchers found that skin thickness, mast cell counts, and immunoreactive density of certain cytokines increased at various stages of hair follicle growth following depilation.

This case study reports a man with rapid hair thinning, whitening, and sparse beard, linked to an increased proportion of hair follicles in catagen or telogen phase and peribulbar lymphocytic infiltrate.

In this study, lipo-minoxidil was found to increase vascular endothelial growth factor expression in the skin of C57BL/6 mice more than standard minoxidil formulations.

This study identified several age-related changes in gene expression associated with the extracellular matrix of scalp dermal fibroblasts, which may impact hair follicle maintenance in women over 40.

This narrative review discusses the hormonal control of hair growth, particularly focusing on dihydrotestosterone and its role in the pilosebaceous unit and androgen-related hair conditions, and does not report new findings.

This study observed that in men with androgenetic alopecia, frontal hair regions showed reduced density, diameter, and growth rate compared to occipital regions, worsening with advanced stages.

This study observed dynamic changes in CD10 and CD34 expression in fetal and adult human hair follicles during embryogenesis and hair cycling.

In this study, five out of six patients treated with vemurafenib for metastatic melanoma experienced hair loss, which improved after topical steroid treatment.
