This source highlights concerns about the safety and efficacy of dietary supplements marketed for hair loss, citing a lack of FDA testing and potential risks such as adverse side effects, interference with medical tests, and withholding of ingredient information.

This correspondence highlights existing research on pattern hair loss, discussing findings about immune deposits, lymphocytic infiltration, and responses to treatment, and calls for future well-controlled studies.

Ketoconazole shampoo can cause rare pink hair discoloration.

This research observed that during the 2 to 4 days following hair transplantation for androgenetic alopecia, patients may develop forehead and upper eyelid edema due to gravitational fluid movement and oozing of inflammatory fluid in the implanted area.

This article discusses the premade slit method in hair restoration surgery, emphasizing the importance of a tailored depth control instrument for optimal follicle implantation, but provides no new clinical results.

This correspondence reports that some men with androgenetic alopecia can exhibit hair thinning patterns more typical of females, with variations observed between Australian and Korean populations.

This study found that extracellular vesicles from low-passage dermal papilla cells may activate hair growth by delivering miR-140-5p, which downregulates BMP2 signaling, suggesting potential therapeutic targets for alopecia.

This study investigated the impact of prolactin and melatonin on secondary hair follicle growth patterns in Angora and Cashmere goats using in vitro methods, without reporting new definitive results.

This study demonstrated that enhancing human skin constructs with hair follicles through engineered cell organization and vascularization improved hair growth in immunodeficient mice, suggesting potential advances for treating alopecia and chronic wounds.

This study found that both human and rat dermal papilla spheroids can induce hair follicle neogenesis, but larger spheroids increase inductivity without significantly affecting hair fiber diameter.

This study found that human hair follicles express erythropoietin and its receptor, suggesting these follicles may use erythropoietin signaling to modulate apoptosis under stress conditions like hypoxia and chemotherapy.

This research reported that squarticles, nanoparticles made from sebum-derived lipids, enhanced the follicular delivery and skin accumulation of diphencyprone and minoxidil, indicating effective drug deposition with reduced systemic absorption in alopecia treatment.

This study found that using 3D dermal papilla spheroid models enhances extracellular matrix production and hair follicle marker expression, providing insights into hair follicle biology and potential for drug screening.

In this study, the researchers reported that chloramphenicol-loaded liposomes, particularly those incorporating deoxycholic acid, enhanced follicular uptake and showed strong antibacterial activity against methicillin-resistant Staphylococcus aureus, offering potential for treating MRSA-infected skin conditions with good skin biocompatibility and minimal toxicity.

This study found that human follicle dermal papilla cells promote survival, proliferation, and tubulogenesis of microvascular endothelial cells, highlighting their significant role in hair follicle vascular remodeling.

This study found that scalp injection of fat enriched with stem cells may offer a promising alternative for treating early genetic alopecia in both men and women.

This study suggests that Ecklonia cava, particularly its component dioxinodehydroeckol, may promote hair growth by enhancing dermal papilla and outer root sheath cell activity in culture and mice models.

This study found that conditioned media from dental pulp stem cells stimulated significantly faster hair growth in mice, suggesting potential as a treatment for alopecia.

This study found that dengue virus infection caused inflammation and cell death in human hair-follicle dermal papilla cells, which may contribute to increased hair shedding observed during the epidemic in Taiwan.

This study found that using cultured mesenchymal stem cells from mouse whisker hair follicle outer root sheath in wound healing reduced inflammation, accelerated closure, and resulted in less hypertrophic scarring in mice.

This study suggests that Platycarya strobilacea extract promotes hair growth in mice by enhancing stem cell factor expression, reducing mast cell numbers, and increasing cytokines associated with hair growth.

This study found that DECORIN promotes the proliferation and migration of outer root sheath keratinocytes in vitro and maintains the hair anagen phase in mice.

In this controlled study on hair transplantation, using autologous plasma as a graft holding solution resulted in better hair follicle cell survival, hair count, and density compared to Ringer's lactate, suggesting plasma's potential to enhance hair graft outcomes.

This study found that adding 7% Ecklonia cava extract to oxidative hair dyes significantly reduced their cytotoxicity and oxidative stress without affecting color performance.

This study observed that micrografts stored at -20°C maintained their morphological structure better than those stored at 4°C, potentially allowing for more efficient hair transplantation procedures.

In this study, mice on a methionine-deficient diet experienced hair loss, which was not remedied by homocysteine supplementation; hair regrowth only resumed after methionine was reintroduced, suggesting dietary methionine is essential for hair maintenance.

This study found that sulforaphane and its related compounds may promote hair follicle growth in mice, suggesting their potential as treatment agents for androgenic alopecia.

This study found that SesZen-Bio TM, a proprietary extract from Sesbania grandiflora leaves, increased proliferation of hair cells and hair shaft length in vitro and ex vivo, potentially due to activation of the Wnt/β-catenin signaling and stem cell differentiation pathways.

This review explores the complex interactions of intrinsic and extrinsic mechanisms that regulate hair follicle stem cells and their role in skin homeostasis, aiming to advance understanding that could support future research on skin disorders.

This study found that hair follicle matrix progenitors differentiate into various layers asynchronously, with early progenitors forming the companion layer and later progenitors generating the inner root sheath and hair shaft.
