The researchers described a chip-based bioreactor platform for dynamic perfusion, which may enhance in vitro skin models by introducing mechanical shear stress and extending culture periods.

This article reviews the historical developments in understanding and treating male pattern hair loss, emphasizing the role of dihydrotestosterone and 5α-reductase inhibitors, but reports no new clinical findings.

This study identifies a bipotent stem cell in adult hair follicles that self-renews and contributes to dermal sheath and papilla cell populations, potentially aiding hair regrowth after injury, disease, or aging.

This article discusses the influence of estrogens on hair follicle growth and metabolism, suggesting a significant role alongside androgens in hair growth control but reports no new clinical results.

This article reviews the biological and physical principles of laser hair removal and reports that current laser systems do not consistently achieve permanent hair follicle destruction across treated areas.

This study found that low-level laser treatment with the HairMax Lasercomb significantly increased terminal hair density in both men and women with pattern hair loss, with no serious adverse events reported.

Different ethnic groups have unique hair growth patterns, with African hair growing slower and less dense, Asian hair growing fast but sparse, and Caucasian hair being densest; men are more likely to experience hair loss than women.

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

This study suggests that the GPX-PDE1 and GPX-PDE2 genes in white lupin enhance root hair development and contribute to Pi limitation acclimation by facilitating glycerophosphodiester degradation.

This article reviews common hair-care practices among African American patients and discusses how these practices relate to hair and scalp disorders, without presenting new clinical research.

This review discusses potential cell sources and bioengineering strategies for regenerating hair follicles with functional cycling, reporting no new results.

In this study, a methanol extract of Eclipta alba was found to have dose-dependent hair growth-promoting activity in C57BL6 mice.

Hair extensions can cause hair loss and scalp damage, and these problems might be more common than people realize.

This study observed that two patients treated with interferon α-2b and ribavirin for chronic hepatitis C experienced complete and reversible straightening of their natural curly hair, which recurred with treatment resumption.

This study found that intradermal administration of adipose-derived stem cell–conditioned medium significantly increased hair density and dermal thickness, suggesting potential regenerative effects on both hair follicles and the interfollicular scalp in patients with alopecia.

This study found that the receptor kinase RHS10 negatively regulates root hair growth in Arabidopsis thaliana by modulating growth duration and is associated with cell wall signal mediation, involving RNA catabolism and ROS accumulation.

This article reviews advancements in hair restoration, highlighting improvements in surgical techniques and patient satisfaction, but reports no new clinical results.

This article provides an overview of recent discoveries about steroidogenic enzymes involved in androgenetic alopecia but reports no new clinical results.

This study demonstrates that incorporating human neopapilla into reconstructed human skin can initiate hair follicle morphogenesis by stimulating epidermal invagination and maintaining follicle-inductive properties in vitro.

This article reviews the causal mechanisms of hair follicle disorders, focusing on inflammation, genetics, environment, and hormones, but it reports no new clinical results.

This review discusses medication-induced gray hair repigmentation, highlighting that certain anti-inflammatory drugs and melanogenesis stimulators can cause diffuse repigmentation, though evidence remains low-quality and these medications are not currently indicated for this purpose.

This review discusses recent advances in hair regeneration therapies, highlighting the potential of nanotechnology and pluripotent stem cells, and reports no new results, emphasizing the need for further research.

In this study, researchers found that a polyphenolic extract from Annurca apples, high in procyanidin B2, increased hair growth, density, and keratin content in healthy subjects after 2 months of use, and stimulated keratin biosynthesis in vitro.

This study found that a bacterial endophyte from Zea nicaraguensis effectively targets and colonizes plant root hair cells, promoting growth and solubilizing insoluble phosphorus for nutrient uptake.

This study reported that follicular unit extraction using nonhead hair sources like the chest or beard may successfully restore hair density and achieve aesthetically pleasing results in severely bald men with limited head donor hair.

This study found that dermal papilla cells cultured in vitro can promote hair follicle regeneration and maintain hair growth, with stronger ET-1 and SCF expression enhancing this regenerative ability.

Human hair follicles have a unique metabolism that changes between growth stages and may contribute to baldness.

This review discusses various approaches to treating alopecia, including drug therapy and hair transplantation, but reports no new research findings; the authors highlight the need for novel techniques like cell culturing.

This study found that using layer-by-layer encapsulation techniques on dermal papilla cells can support their function and may help treat hair loss when used in conjunction with freshly isolated epidermal cells.

This article discusses the use of hair transplantation as a reconstructive method to restore hair in various areas affected by defects, highlighting its advantages in providing natural-looking restoration.
