This review presents updated tables of mouse mutants with hair growth abnormalities to aid in understanding the molecular mechanisms of human hair disorders, but reports no new clinical results.

This study suggests that vellus to terminal hair follicle reconversion can occur in male pattern androgenetic alopecia using an in vivo model with minoxidil and platelet-rich plasma treatment.

In this study, researchers found that the thickness of various skin layers in Bos indicus cattle varied significantly by body region, with the neck and shoulder being thickest, and that male skin might be more suited for quality leather production compared to female skin.

This guide reviews the biology of sebaceous glands and their evaluation methods, emphasizing their roles beyond lipid production in skin health and disease, and reports no new research results.

This practical guide introduces methods to study human dermal white adipose tissue but does not report new clinical results, emphasizing available techniques and staining protocols.

This review discusses current challenges in selective androgen receptor modulator discovery and preclinical evaluation and reports no new results, emphasizing the need for basic research to improve safety and selectivity.

This study concluded that ACD-A vials yielded the highest quality and quantity of platelets in platelet-rich plasma for hair rejuvenation compared to EDTA and sodium citrate.

In this study, the researchers found that transplanted hair follicles undergo significant morphological changes, including a thickened dermal sheath and increased hair shaft diameter, which are associated with altered follicular vascularization.

This study defines classification criteria for hair follicle dystrophy using a mouse model of chemotherapy-induced alopecia, providing tools for standardized hair damage assessment.

This study found that high-dose oral zinc significantly influences hair growth in mice, showing both inhibition and promotion effects depending on the timing and duration of administration.

This study found that the synthetic thyroid hormone receptor modulator KB2115 significantly prolonged the growth phase of human hair follicles in culture without altering mitochondrial activity, suggesting potential as a safer hair loss treatment compared to traditional thyroid hormones.

This study found that in vivo, a novel microneedle system for valproic acid delivery may improve hair regrowth efficacy by upregulating hair follicle development pathways more effectively than topical application.

This study found that low-level laser therapy was the most effective non-surgical treatment for androgenetic alopecia, although the overall quality of evidence supporting various therapies was generally low.

In this study, researchers found that substance P triggered premature catagen development and immune changes in human scalp hair follicles, providing a possible biological link between stress and hair loss conditions like telogen effluvium and alopecia areata.

This study reported that an ex vivo organ culture system effectively induced aging-related changes in healthy human skin, allowing testing of senolytics like tretinoin, resveratrol, and caffeine.

In this study, activated PRP injections appeared to promote hair growth in AGA-affected scalp skin transplanted onto mice, compared to non-activated PRP.

This study introduced a new classification system for distinguishing between anagen VI and early catagen stages in human hair follicle organ culture, using it to confirm eflornithine's ability to induce premature catagen.

This study found that platelet-rich plasma injections significantly improved hair density in male patients with androgenetic alopecia compared to placebo treatments.

In this study, transplanted hair follicles from different body sites showed changes in morphology and immune status, suggesting their ability to adapt and function in new recipient areas such as the scalp or eyebrows.

This study found that human scalp hair follicles can internally operate a Cori cycle, synthesize glycogen in the presence of lactate, and modulate growth through glycogen phosphorylase activity.

In this study, topical application of the SCD1 inhibitor XEN103 significantly reduced sebaceous gland size and number in mouse skin, suggesting potential local therapeutic effects for acne treatment without systemic side effects.

In this study on a murine model, researchers observed that a 5% minoxidil solution reduced stress-induced changes in hair growth, suggesting its potential for managing stress-related hair loss in humans.

In this study, human placenta extract was observed to enhance the hair-growth-promoting effects of minoxidil and stimulate earlier and prolonged anagen phases in a mouse model.

This study found that CARI ONE, a herbal mixture, promotes hair growth in mice by inducing the transition from telogen to anagen phase and enhancing hair follicle development, compared to control and minoxidil treatments.

This study found that dopamine directly induces the catagen phase in human scalp hair follicles in vitro.

This study suggests that with aging, mouse corneal renewal increasingly relies on Lrig1+ stem cells as CD44 expression and Wnt activity decline.

This study found that the PPAR-γ modulator AGED can reverse epithelial-mesenchymal transition in hair follicles affected by lichen planopilaris ex vivo, suggesting potential for treating scarring alopecias.

This study suggests that macrophages play a more substantial role in the pathogenesis of Lichen planopilaris compared to Frontal fibrosing alopecia, as indicated by increased CD68+ cells in Lichen planopilaris.

This study found that dermal white adipose tissue surrounding human hair follicles enhances proliferation, pigmentation, and hair shaft elongation in an ex vivo setting.

This study found that the cell of origin in mouse skin affects melanoma phenotype and response to therapies, despite the presence of the same genetic mutations.
