This study found that Merkel cell clusters require Frizzled6 signaling for their polarity information, while other hair follicle-associated structures align their orientation based on the hair follicle itself.

This study reports that transplanted mouse hair follicles restored piloerection ability and connected properly with host tissues, suggesting potential for advanced hair restoration therapies.

This study found that direct interactions between human dermal papilla cells and melanocytes under low oxygen conditions improved cell functions and could be important for hair regeneration efforts.

This review discusses advancements in understanding hair cycle and inflammatory alopecias, proposing a standard classification and tiered treatment recommendations, but reports no clinical results.

This commentary discusses the mechanisms of progression and potential regrowth in androgenetic alopecia, indicating that the initiation of anagen in kenogen follicles is more critical for hair density improvement than reversing follicle miniaturization.

This chapter provides an overview of chemotherapy-induced alopecia, discussing its biological and clinical aspects, current experimental models and treatments, and calls for improved understanding to prevent and manage it.

In this study, researchers developed a three-dimensional ultrastructural analysis tool using serial block-face scanning electron microscopy to reveal detailed nerve networks and muscle structures in human skin tissues, demonstrating the technique's potential to study structural changes in aging or disease.

This review examines the diversity and role of stem cells in the adult dermis, noting a lack of precise understanding about their hierarchy and relationship to dermal fibroblast subpopulations, and reports no new results.

This study used integrated single-cell chromatin and transcriptomic analyses in developing mouse skin to uncover gene networks involved in skin lineage specification and identified Mef2c+ upper fibroblasts as potential precursors to certain muscle-like structures, with cross-species findings in human skin.

In this study, the researchers explored how the loss of structural integrity in hair follicles due to reduced α-SMA expression in the vertex area may contribute to androgenetic alopecia.

This source reviews mechanisms and existing treatments for hair aging, highlighting factors like oxidative stress and DNA repair defects that affect hair follicle and stem cell function, and discusses research limitations and future directions in the field.

This study found that aqueous extract of Pueraria mirifica, when administered to a rat model, significantly reduced prostate weight, prostatic index, and serum dihydrotestosterone levels, while also improving prostate histomorphology, suggesting its potential as an anti-BPH treatment.

The document suggests that male hormones likely affect hair growth and baldness, and future treatments might involve stem cells and androgen-independent cells.

In this study from a veterinary college, three cats with notoedric mange were treated with weekly subcutaneous injections of Ivermectin (0.2 mg/kg) combined with supportive therapy, leading to successful recovery over four weeks.

Eyelashes are important for looks and eye protection, and more people are treating sparse eyelashes; more research is needed to understand eyelash biology and improve treatments.
