This article discusses the role of dermal papilla and dermal sheath cells in the hair cycle and reviews finasteride and minoxidil's mechanisms in promoting hair growth, but presents no new clinical findings.

This study observed two cases of pigmented epithelioid melanocytoma suggesting potential differing origins: one from a hair follicle's outer root sheath and another from an intradermal nevus.

This study found that tofacitinib and baricitinib had an acceptable adverse reaction profile when used to treat rheumatoid arthritis, with similar side effects to those described in their technical data sheets.

This study found that non-coherent intense pulsed light (IPL) treatment significantly reduced hair growth by about 80% in patients with skin type III-V without causing side effects.

This study detected higher expression of p63 in occipital scalp areas compared to frontal areas, with minimal changes in beta-catenin expression and a novel finding of CD34 positive cells in hair follicles' outer root sheath.

The study found that over-expressing ornithine decarboxylase in the outer root sheath of the hair follicle in mice increases UVB-induced tumor growth and invasive squamous cell carcinoma compared to inter-follicular epidermal keratinocytes.

This study reported that a new coating made with delaminated Ti₃C₂ MXene nano-sheets and a tea-derived compound effectively protects hair keratin from damage by providing UV screening, thermal dissipation, and antioxidation, while also enhancing mechanical strength and restoring wettability.

In this study, a square pulse, low-fluence IPL device used at home significantly reduced terminal hair count by 87% six months post-treatment, with evidence of hair miniaturization similar to professional laser treatments.

This study found that chemical hair straightening significantly reduced hair curl and improved smoothness and shine, but did not significantly affect transverse fissures or split ends, indicating potential benefits with some side effects.

Minoxidil solution can cause skin irritation and allergies in some users.

This study found that in Liaoning cashmere goats, overexpression of the PIP5K1A gene enhances skin fibroblast proliferation, while interference with this gene reverses melatonin-induced proliferation, and PIP5K1A regulates certain miRNA expressions, suggesting a role in improving cashmere yield and quality.

This study observed that a low energy pulsed-light device combined with galvanic energy was effective and safe for reducing unwanted hair in individuals with dark skin types V and VI.

In this study, electrical stimuli at low voltage and frequency settings promoted hair growth in vitro and in rabbit models, possibly by activating pathways like Wnt/β-catenin.

This study discovered a new region in the hair cortex where intermediate filaments are both aligned with the hair's axis and orientationally ordered, influenced by the cuticle boundary.

This study identifies iRhom2 as a crucial regulator of hair follicle differentiation, showing that the iRhom2Uncv mutation leads to dysplasia and reduced TACE maturation, resulting in a hairless phenotype in mice.

Newer midface lift techniques are safer, more reliable, and have quicker recovery times.

This study demonstrated that cryogelation of human hair keratin allows the development of 3D scaffolds with tunable properties, supporting cell adhesion and proliferation for potential biomedical applications.

This article describes how a new blood glucose management service at the NIH Clinical Center improved safety and patient outcomes for hospitalized patients with diabetes.

In this study, UVB irradiation of organ-cultured human anagen hair follicles in vitro reduced hair elongation and increased cell death, affecting hair growth and regulatory processes.

This review discusses available treatments for androgenetic alopecia in men, like finasteride and 5% minoxidil, and notes that hair growth results are unpredictable and often driven by industry-sponsored studies.

This study concluded that stromal vascular fraction and topical minoxidil both improved hair characteristics in male and female patients with androgenetic alopecia, but SVF offered a more satisfactory treatment experience.

This study demonstrated that hair follicle bulge stem cells can form epidermis in a tissue-engineered skin model, highlighting the significance of K5/K17 filaments in slow-cycling stem cell subsets.

This study found that cytokine and EGF stimulation leads to increased MMP-9 production in hair follicles, a process involved in hair follicle involution associated with alopecia.

This study found no association between androgenetic alopecia and increased prostate volume or serum PSA levels in male patients aged 25–45.

This study found that Runx3 deficiency in mice affects hair type and shape, suggesting it may regulate hair formation through interactions between dermal and epidermal layers.

Teak leaf extract hair tonic was tested for hair growth and safety.

This study found that in neonatal mice, the absence of the NG2 proteoglycan leads to reduced epidermal thickness and delayed subcutis thickening due to impaired proliferation and adipocyte deficiencies.

This article reviews sPLA2-mediated phospholipid metabolism using sPLA2 transgenic/knockout mice and lipid mass spectrometry, offering insights into the distinct roles of sPLA2 enzymes in various biological events.

This study described the clinicopathological features of patients with frontal fibrosing alopecia who underwent skin biopsies.

This review outlines key considerations for designing fluorescence microscopy experiments in cell biology, discussing the importance of hardware availability, suitability of biological models, and imaging agents to achieve high-resolution and informative images.
