This study found that loss of contact between the arrector pili muscle and the hair follicle bulge may explain why hair loss in male and female pattern baldness is largely irreversible, unlike in alopecia areata.

This study demonstrated that caffeine, minoxidil, and the HIF-1α-stimulating agent deferiprone significantly enhanced dermal papilla cell proliferation in a 3D culture model, suggesting deferiprone as a potential alternative to minoxidil.

Discoid lupus erythematosus involves immune activation and fibrosis around hair follicles, with shared pathways across humans, dogs, and mice, suggesting potential treatments for both humans and animals.

This report introduces a mouse model with androgen-dependent alopecia, suggesting it as a potential alternative for studying hair loss mechanisms and testing treatments.

This review evaluates laboratory models used in androgenetic alopecia research but reports no new findings, emphasizing the potential of human-derived 3-D models for future studies.

This study found that in a population of hair follicles, regenerative cycling stages are regulated by both intrinsic and extrinsic signals, with WNT/BMP signaling mediating interactions among follicles for adaptability.

This study found that red ginseng oil may enhance hair growth and protect skin from UV damage in mouse models by promoting regenerative processes and reducing inflammation.

This study developed an animal model that recreates alopecia areata by injecting healthy human skin grafts in immunocompromised mice with peripheral blood mononuclear cells enriched for NKG2D+ and CD56+ cells.

This study reports the development of the first rodent model for androgenetic alopecia, demonstrating that overexpression of androgen receptors in mice delays hair regeneration and can be used to test new treatments.

This review introduces an integrated view of hair follicle behavior, highlighting a Yin Yang model of regulation and suggesting glycans as key elements in hair follicle growth control, without reporting new clinical findings.

This review discusses the history and challenges of hair follicle regeneration using follicular fragments and dissociated cells, without presenting new clinical results.

This study reported that a subcutaneous injection formulation using PLGA microspheres to release finasteride stably achieved sustained monthly drug delivery without burst release in beagle dogs, with a dose of 16.8 mg identified as optimal for potential first-in-human trials.

This study developed a new human in vitro hair model that replicates in vivo hair characteristics and may be suitable for high throughput screening of hair growth treatments.

This review discusses recent advancements in behavioral and pharmacological treatments for trichotillomania but does not report new clinical results, emphasizing the need for rigorous future research.

Hair styling products can damage hair over time.

This study demonstrated that injecting reconstructed dermal papilla-like tissues in mice led to new hair growth, suggesting potential future applications in hair transplantation and baldness treatment.

In this study, cinnamic acid was found to enhance hair growth in human dermal papilla cells and hair follicle organoids by activating oxytocin signaling, suggesting its potential for developing hair growth-promoting products.

This study found that the oral Janus kinase inhibitor CP-690,550 has a direct effect on reducing pruritus in patients with psoriasis, independent of clinician-assessed improvements in psoriasis severity.

This study found that using 3D cultures and fetal tissue extracts significantly improved the outcomes of stem cell treatments for regenerative medicine, including hair follicle formation and chronic wound healing.

This source reviews the latest developments in hair transplantation for androgenetic alopecia, suggesting that while medical therapy alone remains unsatisfactory, surgical hair restoration is shown to be highly gratifying for male pattern hair loss.

This study found that homozygous mutant mice with a hypomorphic CD18 mutation developed a chronic inflammatory skin disease resembling human psoriasis, potentially implicating additional genetic factors in disease susceptibility.
