This study found that laboratory and African spiny mice have distinct spatiotemporal patterns in wound-induced hair neogenesis, with the Twist1 pathway playing a central role in epidermal-dermal interactions for hair primordia formation.

This study identified a small population of PAX3+/CD34+ cells in human foreskin tissue that may serve as transition cells between melanocyte stem cells and hair follicle stem cells, characterized by specific marker expressions.

The conclusion is that different types of hair loss in dogs and cats can be cosmetic or serious, and affected animals should not be bred.

In this study, L-PRF was associated with successful osseointegration and tissue healing when used with biomaterial for dental implants in a patient with an atretic bone ridge.

This review evaluates PRP, microneedling, and LLLT for alopecia and telogen effluvium, reporting improvements of 30-40% but offers no new clinical data.

This study demonstrated that litifilimab significantly reduced disease activity in cutaneous lupus erythematosus by Week 16, with improvements most notable in sunlight-exposed skin areas.

In this integrative narrative review, researchers reported that aromatase inhibition using dutasteride and Serenoa repens after hair transplant can effectively preserve follicles and minimize side effects, suggesting personalized strategies may optimize clinical outcomes and patient satisfaction.

In this case report, two young women with female pattern hair loss experienced significant hair regrowth without adverse effects after six months of treatment with bone-marrow-derived mesenchymal stem cells and their extracellular vesicles, suggesting potential for this approach when conventional treatments fail.

This integrative literature review revealed that chronic stress, characterized by elevated cortisol levels, negatively impacts hair follicle integrity and contributes to alopecia by promoting the premature transition from the growth phase to the resting phase of the hair cycle.

This review discusses the role of melanocyte stem cells in skin pigmentation and potential regenerative therapies, but reports no new clinical results.

In this case study, a 35-year-old man with recalcitrant folliculitis decalvans was successfully treated with Erbium-YAG laser, showing rapid improvement without hair loss, though further clinical studies are needed to define its benefits more comprehensively.

In this study, a literature review concluded that minoxidil is safe and effective for treating androgenetic alopecia, with few side effects, and highlighted the role of pharmacists in optimizing treatment by monitoring use and fostering adherence.

This study found that intradermal bleomycin injections induced dermal fibrosis in C57BL/6 mice, evidenced by hair follicle obliteration and dermal thickening, though no significant trends in gene expression were observed, indicating the need for further research to understand the link between fibrosis and dyschromia.

This case report describes an infant with mucopolysaccharidosis type II who developed generalized hypertrichosis after receiving a bone marrow transplant and cyclosporine, highlighting the medication's potential role in exacerbating excessive hair growth and reviewing hypertrichosis causes.

In this integrative review, researchers assessed the efficacy of oral minoxidil for treating alopecia, finding that it appears effective, especially for female androgenetic alopecia, though evidence quality is very low and side effects limit its use compared to topical forms.

This study reviewed literature on phototherapy for hair loss, finding that both high and low-power phototherapy can promote hair growth, but choosing the appropriate power level is essential for effective results.

This study found that PRP treatment showed better results than injectable minoxidil for reducing hair loss and promoting hair growth, with noticeable effects after the second application.

This study found that skin bacteria promote regeneration in wound-induced hair follicle neogenesis, suggesting a role for IL-1β signaling and challenging the belief that infection inhibits healing.

This chapter classifies various benign skin tumors and discusses their characteristics, treatment indications, and potential for recurrence, but reports no new clinical findings.

This study highlights the significance of SFRP2 expression in dermal papilla cells, noting its correlation with the inductive potential for hair growth, although its role may be more indicative than transformative.

A woman developed thick gums from everolimus treatment after a kidney transplant.

Polymethylene wax in hair relaxers makes hair smooth and shiny with less damage.

This research observed that finasteride-loaded ethosomes showed improved permeation across rat skin and human cadaver scalp skin compared to unencapsulated finasteride, potentially enhancing delivery to hair follicle units.

This review summarizes fundamental concepts and recent advancements in hair follicle biology, including insights from mouse models into broader molecular and cellular processes relevant to regeneration and development.

This study found that IL-17A-producing γδ T cells play a key role in bone fracture healing by promoting bone formation, with deficiencies leading to impaired repair in mice.

This study suggests that skin-derived precursors from Sox2(+) hair follicle dermal cells have the potential to function as dermal stem cells, supporting hair morphogenesis, dermal maintenance, and wound-healing.

This study found that Wnt signaling in the hair follicle is crucial for coordinating the behavior of epithelial and melanocyte stem cells, which drives hair regeneration and melanocyte differentiation in mice.

This review discusses the identification and characteristics of melanocyte stem cells, emphasizing their role in hair pigmentation, greying, and skin repigmentation, but reports no new research findings.

In this mouse study, researchers found that dermal Wnt signaling/β-catenin activity is essential for fibroblast proliferation and initiating hair follicle formation by interacting with epidermal Wnt ligands.

This review discusses the various stem cell populations associated with hair follicles and their potential in regenerative medicine, highlighting differences between murine and human hair follicles but reports no new clinical results.
