This study found that Sox2 and BMP signaling may be key regulators of pigmentation and melanocyte migration, as suggested by experiments in mice, human biopsies, and cell co-cultures.

The document concludes that diagnosing hair loss requires evaluating multiple histological features, as no single feature is definitive on its own.

Temporal triangular alopecia is a lifelong condition with hairless patches on the side of the head that may be present from birth.

This article offers practical guidance on specific techniques for surgical hair restoration repairs, emphasizing meticulous techniques and optimal use of limited hair supply to achieve improved cosmetic results.

Best hair transplant results happen when tissues are least damaged.

Auto-portraits help evaluate scalp hair.

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.

In this study, the researchers found that combining physical dermabrasion with chemical peeling increased growth factors and neuropeptides more than chemical peeling alone in porcine skin samples.

This article reviews the occurrence of ectopic sebaceous glands in hair follicle matrix during hair embryogenesis and reports no new clinical results, indicating unknown pathogenesis and clinical implications.

Understanding skin structure and development helps diagnose and treat skin disorders.

In this study, nanoemulsion formulations were found to significantly enhance the skin retention of the antiseptic agent triclosan, with the optimal mixture being a low surfactant concentration, as demonstrated through quantitative and qualitative analysis using tape-stripping and micro CT scans.

This review discusses various strategies to enhance drug delivery through the skin barrier, highlighting liposomes as promising carriers for increased dermal concentrations in topical therapies, but reports no new research results.

This study found that anagen-phase hair follicles in mice are particularly sensitive to damage by ruby laser pulses, resulting in alopecia without scarring, suggesting enhanced laser hair removal strategies.

Alpha-hydroxy acids, like glycolic acid, safely improve skin issues and work on all skin types.

This review explores embryonic epidermal development and discusses key molecular regulators and roles of the sub-epidermal mesenchyme, but reports no new experimental results.

This study found that a new topical nitric oxide gel significantly accelerated burn wound healing in mice by enhancing re-epithelialization, hair follicle regeneration, collagen deposition, and angiogenesis compared to controls.

This review discusses advances and challenges in skin tissue engineering, focusing on developing 3D constructs for functional skin substitutes, and reports no new clinical results.

This review indicates that microneedle bipolar RF and fractional bipolar RF treatments offer significant improvement in acne scarring, with optimal results observed about three months after treatment.

This study found that the PI3K-Akt signaling pathway is essential for regenerating new hair follicles when epidermal stem cells and skin-derived precursors are combined, suggesting potential therapeutic applications for hair regeneration.

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 review discusses the hormonal influences on hair cycling disorders in post-partum and postmenopausal women and notes the lack of evidence for effective targeted treatments.

In this study, fractional laser treatment was observed to reverse age-related gene expression changes in skin and enhance dermal remodeling, further improved by multiple treatments.

This review discusses the use of laser and flashlamp technology for unwanted hair removal and reports no new clinical results, highlighting challenges with light-colored hair and treatment safety for darker skin tones.

This study found that using a combination of iontophoresis and liposomal delivery facilitated the effective intradermal administration of superoxide dismutase in rats, reducing oxidative skin damage from UV exposure.

This review discusses the use of laser and intense light sources for hair removal and reports no new clinical results; the authors highlight the potential for aesthetic medicine to include these technologies.

This chapter discusses the skin stem cell niche as a complex ecosystem and highlights the diverse components and interactions that influence stem cell function, but it reports no new experimental results.

In this study, combining microneedle and sublative fractional radiofrequency treatments significantly improved skin tightening, texture, collagen organization, and satisfaction in individuals with moderate photoaging, while reducing abnormal elastin after three months.

This study characterized the hair follicle patterns of Indian bison, Black buck, and Nilgai, providing valuable data to help identify these endangered species' skins, commonly targeted by poachers.

This study found that experimentally induced hypothyroidism in rats is associated with impaired skin structure, but topical application of triiodothyronine (T3) improved these changes to resemble normal skin.

Hair follicles could be used for targeted drug delivery, with liposomal systems showing promise for this method.
