This study found that oral isotretinoin achieved good to excellent clinical results in treating severe inflammatory acne, severe rosacea, and gram-negative folliculitis.

This forum article in BMC Biology discusses evolving views on the concept of the stem cell niche, highlighting varied mechanisms and the need for better understanding of the niche's roles and functions.

This review examines the role of hair follicles and sebaceous glands in percutaneous drug delivery but does not report new clinical results; it calls for further exploration of follicle-targeting therapies.

In this study, researchers found that bulge cells in mouse hair follicles undergo transient proliferation during early anagen, indicating their role as follicular stem cells. However, another factor beyond dermal papilla proximity may be required to initiate a new anagen phase.

This review explores the biology of wool follicles and suggests their potential use as research models in modern biology, but it reports no new findings.

This review explores the hormonal regulation of hair growth and changes with season, age, and sexual development, and calls for improved treatments for hair disorders.

The human hair follicle can store topical compounds and be targeted for drug delivery with minimal side effects.

This review describes recent advances in using nanoparticles for drug delivery to hair follicles, with potential applications in treating skin diseases such as alopecia and acne, but reports no new findings.

Minoxidil works in liver and outer hair root sheath for hair growth.

This study found that overexpressing PLC5 in Arabidopsis thaliana reduced root growth but improved drought tolerance, and suggests PIP2 is crucial for root hair growth.

This review highlights the need for methodologies to understand and quantify drug penetration into hair follicles as significant drug pathways, noting this area lacks comprehensive articles and reports no new results.

This review discusses the structure and regenerative potential of hair follicles, highlighting their role in wound healing, stem cell populations, and keratin-based biomaterials, but it reports no new clinical results.

This study found that subcutaneous injections of guanethidine or 6-hydroxydopamine induced premature hair growth in mice, suggesting a role for sympathetic nerves in hair growth control.

This review examines the cognitive effects of medications for lower urinary tract symptoms and indicates that muscarinic antagonists, particularly oral oxybutynin, pose the highest risk for cognitive impairment.

Hair growth is influenced by factors like genetics and nutrition, and more research is needed to understand hair loss and growth mechanisms.

This study found that Hoxc13-/- rabbits exhibit complete hair loss on the head and dorsum, providing a potential model for understanding human ECTD-9 and related dermatological conditions.

This review discusses the structure, functions, and growth cycle of human hair, emphasizing its reduced growth and protective roles, and reports no new research findings.

This review discusses studies on hair growth and protein synthesis in hair follicles, highlighting the differing responses of mohair and cashmere goat follicles to signaling molecules, biotin, and amino acids, but contains no new results.

This study found that EGFR inhibitors and ligands did not significantly affect the expression of inflammatory biomarkers in cultured sebocytes, except for a notable increase in IL-1 expression with EGF treatment.

This review discusses the potential of using human hair proteomics for non-invasive diagnostic and forensic applications but reports no new results; the authors highlight areas needing further research.

Targeting drugs to hair follicles can treat skin conditions, but reaching deep follicle areas is hard and needs more research.

This article discusses the role of clinical observation and microscopic correlation in American dermatology training and reports no new clinical results.

This study found that Prss53-mutated rabbits exhibited curved hair and skeletal dyskinesia, suggesting a link between Prss53 loss and these traits, potentially involving disrupted calcium metabolism.

This study found that normal murine hair follicles are direct targets for melatonin bioregulation, expressing receptors that are regulated in a hair cycle-dependent manner, influencing keratinocyte apoptosis.

This article discusses the histologic features of psoriasis, including psoriasiform epidermal hyperplasia and neutrophilic involvement, but reports no new clinical findings.

This study describes a simplified method for isolating and cultivating human hair follicle papillae that can be easily executed by new lab personnel.

This paper discusses the hypothesis that anti-acne agents may work by reducing FGFR2 signaling, and emphasizes FGFR2's potential role in acne pathogenesis, but it reports no new experimental findings.

This review discusses the potential therapeutic effects of targeting the endocannabinoid system for chemotherapy-induced peripheral neuropathy and reports no new clinical results, highlighting the need for ongoing research.

This review revisits the mechanisms of wound induced hair follicle neogenesis in mice and concludes that the process involves canonical WNT signaling activated by Fgf9 from γδ T cells, but more research is needed to fully understand its cellular bases.
