This study demonstrated that a 3D air–liquid culture system using Wnt-CM-treated cells can induce hair regeneration in nude mice and may facilitate large-scale preparation for hair loss treatment.

This review examines non-invasive methods for diagnosing inflammatory skin diseases like lupus erythematosus and psoriatic inflammation using samples from plucked hair and skin tape-strips, but no new clinical results are presented.

In this study, the researchers observed that inducing and then withdrawing β-catenin expression in a bigenic mouse model caused reversible changes in skin morphology, indicating dependence on β-catenin signaling.

This review summarizes current knowledge on tight junctions in mammalian skin and their role in drug delivery and interaction with other barrier components, but reports no new experimental results.

This review discusses the use of ablative and nonablative fractional resurfacing for enhanced topical drug delivery in dermatology and reports no new clinical results; further studies are needed to explore these methods.

This study concluded that combination therapies often yield better results for treating atrophic post-acne scars than single treatments.

This review discusses the growing use of scalp hair for elemental analysis in various fields and highlights advancements in analysis techniques, including the future potential of laser ablation ICP-MS, but reports no new clinical results.

This study found that horizontal sections of scalp biopsies in patients with Central Centrifugal Cicatricial Alopecia often reveal follicular miniaturization, inflammation, and scarring, which can guide personalized treatment.

This review highlights the positive effects of platelet-rich plasma in aesthetic and regenerative medicine, particularly for skin rejuvenation, anti-aging, hair reconstruction, and wound healing, but it reports no new clinical results.

This article reviews the classifications and characteristics of androgenic alopecia and provides no new clinical results; it emphasizes the importance for aestheticians to understand current treatment evidence.

This study found that both 5-ALA and Photofrin can effectively destroy human microvascular endothelial cells in vitro and cause tissue necrosis in vivo, with Photofrin showing greater efficacy at lower concentrations or power densities.

This review examines the devices, mechanisms, risks, side effects, and regulatory differences in laser hair removal, particularly highlighting the lack of regulation in South Africa and its implications for patient safety.

This review discusses skin diseases in transgender patients receiving gender-affirming hormone therapy and procedures, highlighting unique conditions and the underdiagnosis that affects their quality of life and mental health.

This study analyzed trends in consumer and physician interest in nonsurgical hair loss therapies, finding that internet searches for treatments like minoxidil and low-level laser therapy increased over time, influenced by regulations and social media.

In this study, researchers found that in the UK, laser treatment for hidradenitis suppurativa had the highest participant eligibility and preference compared to other interventions, highlighting its potential priority in future trials.

Junctional proteins stabilize the inner root sheath and connect the companion layer in human hair.

In this study, researchers observed significant differences in hair follicle microbiome diversity and microbial composition between hair loss and healthy groups, uncovering specific patterns and functional changes associated with female pattern hair loss, which may aid future targeted approaches for androgenetic alopecia.

This review discusses the chemical stability of protein envelopes found in the epidermis and other stratified squamous epithelia, but reports no new clinical results.

This study found that lysine carboxymethyl cysteinate helps protect the epidermis from UVB-induced damage by activating autophagy and restoring cornification processes in a skin model.

This review discusses the role of TGM3 in skin and hair follicle biology, human tumor pathology, and genetic abnormalities, and reports no novel results; the authors highlight its potential as a cancer diagnostic biomarker.

In this case report, a 31-year-old male using topical minoxidil for androgenic alopecia developed diplopia and increased intraocular pressure, which improved after stopping minoxidil and using prostaglandin analogues, although a carbonic anhydrase inhibitor caused IOP to rise again during follow-up.

This study describes the structure and composition of the epidermal horny layer in elephant seals, noting that its keratinized cells are attached without a specialized fission zone, differing from the sloughing mechanism in reptiles.

This review discusses Wnt signaling pathways in skin development and stem cell regulation, highlighting potential interactions with other pathways but reports no new findings.

This study reports that human eccrine sweat gland cells are capable of forming a stratified epidermis, suggesting they may serve as an additional source of keratinocytes for skin repair.

In this study, researchers found that the absence of type I or type II keratins in mice leads to severe skin barrier defects, highlighting keratins' crucial role in epidermal structure and function.

This study demonstrates that PAD1 and PAD3 are involved in hair follicle differentiation, while PAD1 and PAD2 may play a role in the physiology of sweat glands and arrector pili muscles.

This study found that the co-ablation of C/EBPalpha and C/EBPbeta in adult mouse skin disrupted sebocyte differentiation and epidermal homeostasis, highlighting their critical roles in these processes.

This study found that the serine protease BSSP is strongly expressed in mouse skin during carcinogenesis and is upregulated independently of c-Fos and unaffected by glucocorticoids.

This study suggests that the structure and function of the inner root sheath in mammalian hair may have evolved from simpler forms seen in monotremes, aiding in hair exit without damaging the epidermis.

This study found that WWOX deficiency in mice leads to impaired skin development, reduced epidermal thickness, and significant hypothermia due to disrupted cell proliferation and homeostasis.
