In this study, researchers using the hair paradigm highlighted how periodic patterning and compartmentalization enable diverse regenerative behaviors, including region-specific renewal cycles and emergent properties like regenerative waves in organ populations.

This study found that cultured human dermal papilla cells formed into three-dimensional spheres have an increased ability to induce hair follicles from mouse epidermal cells compared to two-dimensional cultures.

This study observed three hair follicle-like cells from cultured human foreskin keratinocytes, suggesting a potential basic framework for hair regeneration applications.

This review highlights that herbal nanoemulgel-based hair dyes, enriched with natural ingredients, improve dye penetration and retention and offer additional hair and scalp benefits compared to conventional dyes, although further research is necessary to verify their safety and efficacy for long-term use.

This study found that gene-regulatory interactions among parental alleles contribute significantly to heterosis in early stages of maize development, with many differentially expressed genes showing non-additive expression in hybrids.

This study observed in mouse skin that trichohyalin granules in hair follicles transform into filamentous structures as inner root sheath cells differentiate and cornify.

In a clinical phase I/IIa study, subcutaneous injections of the peptide FOL-005 increased hair growth by 8% and were safe for treating alopecia.

This study highlights confocal microscopy as a promising, minimally invasive tool for assessing hair morphology and internal structures, making it valuable for cosmetic hair assessments.

Oxidation changes the structure of hair protein filaments, causing them to compact and rearrange.

This study examines the use of emulgel-based systems as drug delivery vehicles for hydrophobic medications, noting their potential benefits in dermatological applications due to properties like easy spreadability, non-greasy texture, and prolonged shelf life.

This study found that human hair follicles demonstrated a dose-dependent response to light in an ex vivo photoepilation model, which could predict the clinical efficacy and permanency of light-based hair removal devices.

This review highlights hypochlorous acid's potential benefits in various medical fields due to its antimicrobial and healing properties but stresses the need for further research on dosing and product development.

This study observed that in vitro cocultures of hair follicle cells with dermal fibroblasts or hair papilla cells enhanced proliferation and differentiation of outer root sheath cells but did not mimic hair-type differentiation.

The hydrogel helps heal seawater-immersed wounds by reducing infection and inflammation.

This review discusses recent advances in understanding the structural hierarchy of trichocyte keratins, including their heterodimeric structure and distinct conformations impacting hair growth, with no new experimental results reported.

The researchers reported that basement membrane heterogeneity, especially laminin α5 composition, plays a critical role in distinct inter-tissue interactions and hair cycle regulation in mouse hair follicles.

In this study, researchers developed a coamorphous form of tadalafil and finasteride, showing improved solubility and dissolution in vitro, with results successfully translated in vivo in rats. They reported reasonable stability, suggesting this form could serve as a therapeutic alternative to the current marketed combination.

Human hair follicles have a unique cell distribution and differentiation pattern during growth.

This review discusses the potential of lecithin organogels for improving topical drug delivery and presents no new experimental results; the authors highlight their stability and low skin irritancy as advantages.

In this study, OCT showed strong nuclear binding in certain skin cells, suggesting similar genomic effects to vitamin D with potential therapeutic benefits due to its lower calcaemic effect.

This study demonstrated that CD anisotropy effectively distinguishes between two polymorphs of finasteride with nearly identical electronic circular dichroism spectra, using imaging and simulated spectra to uncover unique signatures that traditional methods miss.

This study demonstrated that combining amorphization and nanonization of drugs enhances both saturation solubility and dissolution rate, potentially offering therapeutic benefits for formulations like dermal applications.

This study revealed that Patched receptors establish a Hedgehog signaling gradient in developing hair follicles, which may influence their formation and potentially offer a diagnostic tool for distinguishing Hedgehog-driven tumors.

This study used single-cell RNA sequencing to identify at least nine subpopulations of keratinocytes in human neonatal epidermis, revealing unexpected heterogeneity and complex differentiation trajectories.

This study found that a bulge stem cell-enriched population from canine hair follicles successfully formed interfollicular epidermis in vitro within two weeks, suggesting potential for regenerative canine skin therapies.

This study developed a model using homogenization-based framework to quantify solvent and solute flow across Janus membranes, aiming to better understand interface phenomena like osmosis and phoresis by examining micro- and macro-scale behaviors.

In this study, researchers mapped gene expression in developing hair follicles to reveal unknown cell populations and markers, suggesting early establishment of cell fates in hair placodes.

This study describes the presence of holes in hair fibers, absent in hair follicles, likely forming from daily care actions and removal of extractable substances.
