In this study, dermal papilla cells from rat vibrissae showed potential for treating CNS injuries by secreting neurotrophic factors and promoting neuronal differentiation more effectively than bone marrow mesenchymal stem cells.

This study explored the potential use of natural ingredients in managing alopecia areata, investigating their safety and efficacy as alternatives to conventional chemical treatments.

In this study, 41% of participants reported experiencing alopecia post-COVID-19, with notable associations found between the condition and female sex, azithromycin use, and symptoms like fatigue and post-infection skin irritation.

In this study, the novel ASAXA-μCT imaging method identified that the shrinkage of sweat glands with aging causes dermal defects, reducing skin elasticity and contributing to wrinkling and sagging.

Advancements in biomaterials and nanotechnology are improving medical applications like hair growth, bone regeneration, and cancer treatment.

Dermatologists should know about cosmetic science and aesthetics because patients care about skin appearance and health.

This source notes that Olumiant (baricitinib), a rheumatoid arthritis drug by Eli Lilly and Company, has been approved as the first systemic treatment for severe alopecia areata.

This study found that diffuse and pseudo-fringe sign patterns are common in Asian patients with frontal fibrosing alopecia, and that treatments combining antiandrogens or antimalarials with topical therapy are effective.

This study demonstrated that RNA-seq can effectively expand hair follicle transcriptomic profiling in a multi-center study, offering deeper insights than blood transcriptomics alone.

This research found that the most cost-effective extraction for developing a coffee-based hair serum is from fall grade cherry coffee, which balances active ingredient content and material cost effectively.

This study revealed that Thai youths who are more worried about androgenetic alopecia tend to experience higher severity of the condition, poorer quality of life, and increased use of multiple hair styling products.

In this study, researchers identified PSENEN mutations that can lead to a form of Dowling-Degos disease, characterized by follicular hyperkeratosis and an increased susceptibility to acne inversa, especially in the presence of certain trigger factors.

This study found that blue light at a wavelength of 453 nm promoted hair growth ex vivo, potentially through interacting with OPN3 receptors in human hair follicles.

This study found that Wnt signaling, crucial for lung development, may be disrupted in severe asthma, potentially affecting cell proliferation and senescence through complex mechanisms.

This study found that low massage frequencies like 4.2 Hz enhance nanoparticle penetration into hair follicles more effectively than higher frequencies, indicating potential applications in therapeutic and cosmetic delivery.

This review describes how liver and kidney diseases and diabetes may affect ethyl glucuronide levels in hair, impacting forensic and clinical interpretations, but reports no new experimental results.

This study found that postmortem root banding in hair is likely due to the degradation of the intermacrofibrillar matrix in the cortex, with no damage to the cuticle observed.

This study reports that keratinocytes grown under low oxygen conditions (physioxia) demonstrated reduced reactive oxygen species production and increased antioxidant enzyme activity compared to those in higher oxygen conditions, highlighting the role of oxygen in regulating skin antioxidant defenses.

In this study, using an ex vivo porcine skin model, researchers found that a 4% nanoparticle concentration significantly enhanced the transport of fluorescein sodium into hair follicles compared to a 2% concentration, while higher concentrations did not further increase penetration depth.

This review summarizes recent research on the therapeutic uses of adipose-derived stem cells for wound healing and treating skin diseases but does not provide new experimental results.

This study found that a novel shampoo formulation effectively delivers caffeine to hair follicles, with 8–9% of absorbed caffeine reaching the follicles, suggesting it may support hair retention by enhancing antioxidant activity.

This study suggests that UVA-responsive nanocapsules may provide an effective method for skin antisepsis by releasing ethanol and reducing microorganisms within hair follicles on ex vivo porcine ear skin.

Managing skin diseases during pregnancy and postpartum requires careful consideration of treatment safety and dosing to protect both mother and baby.

In this study, researchers developed a new 6-point scale for evaluating heat damage to hair from straighteners, finding a strong correlation between technical damage measurements and human perception of hair damage.

This study found that in a human skin organ culture model of pemphigus vulgaris, split formation led to significant upregulation of IFNγ and TNFα-related genes, indicating secondary effects from mechanical stress, not direct changes from autoantibodies.

This study developed a deep learning-based tool to quantify individual hair fibers in mice, revealing distinct hair phenotypes linked to hormonal, genetic, and age-related factors, and suggesting its potential for new diagnostic methods through hair analysis.

In this chapter, researchers discuss how microRNAs (miRNAs) interact with vitamin D signaling, highlighting their emerging role as mediators in vitamin D-regulated disorders and their potential for developing miRNA-based clinical applications.

This study suggests that individuals with severe sickle cell disease, indicated by higher hemoglobin S and ferritin levels, may have lower cortisol levels as shown by reduced hair cortisol content.
