This study found that in thin cutaneous melanomas, tumor regression is associated with a higher risk of sentinel lymph node involvement.

This review discusses the causes, associated conditions, and treatment options for alopecia areata, such as corticosteroids and wigs, but reports no new clinical findings.

This review discusses the current understanding of hair photodamage and photodegradation and reports no new findings; it highlights unresolved questions about radiation effects and melanin's role in different hair types.

This review found that infliximab, golimumab, and some forms of radiotherapy significantly improved nail psoriasis compared to controls, although they could have serious adverse effects and are not commonly used specifically for nail issues.

This study found that inhibiting PKC-β activity with bisindolylmaleimide reduces pigmentation in the skin and hair of guinea pigs and mice by preventing tyrosinase activation.

This study observed that in aged mouse skin, there was an increase in IL-17-expressing T helper cells, γδ T cells, and innate lymphoid cells, and blocking IL-17 signaling reduced skin inflammation and delayed age-related changes, suggesting it as a potential target to mitigate skin aging.

This review discusses the development and application of multiphoton microscopy in dermatology, highlighting its advantages and potential future research directions without reporting new clinical results.

This review highlights the challenges in treating alopecia areata, noting that current therapies often lead to relapse and have uncertain long-term effectiveness; it also points to potential future treatments such as JAK-STAT inhibitors and PRP.

In this study, UVB irradiation of organ-cultured human anagen hair follicles in vitro reduced hair elongation and increased cell death, affecting hair growth and regulatory processes.

This article examines differences in aging among ethnic populations and highlights cosmetic procedures specific to skin of color, but reports no new research findings.

This review examines around 68 plant sources from six major plant families, assessing their scientific rationale and use by the cosmeceutical industry for applications like anti-ageing and sun protection.

This study found that human iPSC-derived melanocytes from vitiligo patients successfully integrated into mouse hair follicles and epidermis, demonstrating potential for personalized therapy for depigmentation.

This study found that a novel proniosomal gel formulation of CoQ10 improved antioxidant levels and provided better skin protection against UV radiation compared to a conventional CoQ10 gel in animal models.

This article reviews phenotypic variability linked to WNT10A nonsense mutations and does not present new research findings.

This study reported that sunscreen with SPF50+ provides a high level of DNA protection against UV-induced damage in a reconstituted human epidermis model, comparable to that in skin explants.

This study found that conditioned media from epidermal progenitor cells improved skin aging signs in a clinical trial and protected fibroblasts from oxidative stress in vitro.

In this study, researchers identified novel long non-coding RNAs related to cashmere fineness in goats, highlighting a potential regulatory network involving lncRNA XLOC_008679 and its target gene KRT35.

This study provides evidence-based recommendations for the off-label use of topical vitamin D in treating certain skin conditions, but highlights the need for higher quality studies for further validation.

Pollution exposure speeds up hair damage.

This chapter reviews formulation principles for creating cosmetic nanoemulsions and applications targeting skin and hair care, but does not present new experimental results.

Bimatoprost can cause longer, thicker, darker eyelashes and eyebrows.

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 the small molecule honokiol may protect against inflammation, collagen breakdown, and cell damage caused by cigarette smoke in skin cells cultured in vitro.

This review discusses the effectiveness of non-thermal, non-ablative devices like light-emitting diodes in treating various skin and hair conditions but reports no new clinical findings.

This review provides guidance on using two-photon microscopy for real-time and long-term visualization of stem cell activity in live mice skin, focusing on its application in researching skin and stem cell biology.

In this study, adipose tissue secretome was shown to enhance oxidative stress resistance and promote cell proliferation in vitiligo cells, suggesting a potential natural treatment approach.

This study found that stressed dermal fibroblasts significantly increased dopa oxidase activity in melanocytes from hair, skin, and eyes, suggesting the involvement of fibroblast-derived factors like basic Fibroblast Growth Factor.

This study observed that aging leads to significant structural and biological changes in the scalp's hair follicle environment in women, which may affect hair growth.

In this study, PKC ε transgenic mice exposed to ultraviolet radiation showed increased hair follicle stem cell frequency and altered gene expression compared to wild-type mice, suggesting a potential role in skin cancer susceptibility.

This review discusses the unique dermatologic needs and conditions affecting women of color, noting specific skin and hair conditions but reports no clinical results.
