In this study, mice exposed to prolonged space conditions demonstrated skin atrophy, altered hair follicle cycles, and significant changes in the gene expression associated with skin muscle health.

This review discusses chemotherapy-induced hair loss, highlighting that topical minoxidil can lessen its severity or duration but not prevent it, and reports no new clinical results.

This study found that KAP7.1 and KAP8.2 genes were significantly more expressed in secondary hair follicles than primary follicles, suggesting their role in regulating cashmere fiber diameter.

This review discusses recent advancements in understanding hair follicles, their disorders, and potential therapeutic opportunities, but it reports no new clinical findings.

This study observed that retinoic acid biosynthesis and signaling in hair follicles have a spatial and temporal regulation linked to distinct stages of the hair cycle in mice.

This study found that cultured dental papilla cells from various mammals can induce hair follicle regeneration and influence tissue formation, with outcomes dependent on donor age, tooth type, and host environment.

In this study, researchers found that size polymorphisms in certain hKAP1 genes are linked to the hKAP1.1B and hKAP1.3 genes, arising from intragenic deletions and duplications in Japanese and Caucasian populations.

In this study, hair pain (trichodynia) was reported by a significant portion of patients with hair loss, but it did not correlate with the cause or activity of the condition.

This study reports that trichocyte intermediate filaments from rat vibrissae and human hair follicles may contain a hollow region at their core, suggesting unique structural properties.

This study developed a rapid, cost-effective three-dimensional skin equivalent model using human dermal fibroblasts, collagen, and hair follicles, which closely resembles natural human skin and can be used for autologous transplantation.

In this study, researchers created a mutant mouse lacking the first cut repeat in the Cux/CDP protein, resulting in curly vibrissae and wavy hair, supporting the role of Cux/CDP's DNA binding domains in gene regulation during development.

In this study, melatonin implants advanced and synchronized spring hair growth in goats by initiating fiber growth earlier than in untreated goats, with associated suppression of normal prolactin rise.

This study found that hair follicle and interfollicular epidermis stem cells contribute differently to skin regeneration, with their persistence influenced by factors like spatial constraints and competition moderated by Notch suppression.

This study found that self-noncoding dsRNA activates TLR3 to stimulate intrinsic retinoic acid synthesis, promoting new hair follicle formation in wounded mice and showing similar gene expression changes in humans treated with rejuvenation lasers.

Keratin peptides can change hair shape gently without harsh chemicals.

This study found that DKK1 and WNT10b are paracrine factors that modulate hair follicle stem cell differentiation inhibition, contributing to androgenetic alopecia by affecting Wnt signaling in androgen-sensitive dermal papilla cells after dihydrotestosterone stimulation.

This study found that while the reproducibility of hair cortisol measurements in captive chimpanzees was high, the fineness of homogenized hair, sample weight, and extraction time influenced absolute cortisol concentrations.

This review discusses the need for an updated 'European hair cosmetic series' to include common contact allergens and remove outdated substances based on current evidence and regulations, but it reports no new results.

This study concluded that polymeric nanoparticles effectively targeted hair follicles for drug delivery, but the organogel formulation did not enhance their penetration into the hair shaft.

This review explores genetic and lifestyle factors influencing hair diversity and reports no new findings, calling attention to the potential for future discoveries in genetic and epigenetic research.

This review examines the pathogenesis of premature hair graying and potential treatment avenues, but reports no new experimental outcomes, highlighting ongoing research challenges and hopes for drug development.

This article reviews the generation of complex integument patterns through genetic, chemical, and environmental influences, with applications in tissue engineering, but reports no new experimental results.

This study suggests that the neuropeptide CGRP may protect against, but not restore, IFNγ-induced collapse of hair follicle immune privilege in alopecia areata.

This study found that treatment with a 1550 nm fractional erbium–glass laser increased hair density and thickness in women with female pattern hair loss, suggesting it may be an effective and safe option.

This study found that women with androgenetic alopecia experience diffuse hair loss due to a decrease in terminal hairs and an increase in vellus hairs per follicular unit.

This review discusses how various factors, including cosmetic procedures and scalp conditions, can damage hair, but highlights the availability of products to improve hair health; it reports no new empirical results.

This study provides evidence supporting a regulatory relationship between the transcriptional regulator Hoxc13 and Krtap16 genes, which are crucial for proper hair growth in mice.

DS cells in hair follicles can help form and restore hair, especially in hair loss conditions.

This study identified a novel missense mutation in the hairless gene in a Polish family, which may contribute to congenital atrichia with papular lesions by affecting the gene's function.

This study found that overexpressing human Bcl-2 in mice protected epidermal keratinocytes from UVB-induced apoptosis but unexpectedly increased apoptosis during hair follicle regression and chemotherapy.
