In this split-scalp study, researchers observed that combining fractional CO2 laser and PRP treatment was significantly more effective in improving hair parameters in women with female pattern hair loss than using each intervention alone or placebo.

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.

Androgenic alopecia causes hair follicle degradation and skin restructuring, but some hair elements remain.

This study suggests that programmed cell death plays a crucial role in shaping the structure of the human epidermis and its appendages during development.

This study found that transplanting hair follicles into human scars may remodel fibrotic tissue and reduce scarring by altering collagen structure and decreasing pro-fibrotic factors.

This case study reported on a 72-year-old woman initially diagnosed with inflammatory alopecia, later identified as having angiosarcoma of the scalp, revealing the importance of considering unexpected malignancies during evaluation of suspected inflammatory alopecia cases.

This review discusses the potential of using SULT1A1 expression in the scalp as a biomarker to predict response to minoxidil treatment for androgenetic alopecia, but reports no new clinical results.

This study found that using an electrical microneedling device enhanced the penetration of liposomal melanin-fluorescein into hair structures and widened the follicular infundibulum in ex vivo human skin models.

This study found that aging in Korean individuals is associated with changes in hair diameter and surface structure, as observed through atomic force microscopy.

This study found that scalp hair follicles had higher expression of cytokeratin 15 and distinct hair layers compared to other body regions, highlighting differences in hair follicle characteristics.

In this study, researchers found that the original four-factor model of causal illness attributions in the IPQ-R did not fit a Chinese sample, and instead identified a two-factor model focusing on psychological attributions and risk factors.

This study identified changes in immune activation, ferroptosis, and structural genes in alopecia areata subtypes, suggesting molecular markers that might help understand disease variability and guide future treatments.

The document concludes that scalp health is influenced by complex factors affecting sebaceous glands, including hormones, aging, and various substances.

This study found that understanding the surgical anatomy of the scalp significantly improves outcomes in scalp surgery by reducing complications like unsightly scars and distorted hair patterns.

This case report documented a 74-year-old female with alopecic patches and other skin issues during talquetamab therapy for multiple myeloma, suggesting that the drug may cause skin-related adverse effects due to reactivity to GPRC5D-expressing structures.

This study found that scalp melanoma often occurs in areas with androgenetic alopecia, and patients without alopecia might experience a later diagnosis due to hair coverage, leading to potentially worse outcomes.

This study identified a novel keratin-associated protein, KAP24.1, which is specifically expressed in the human scalp and located in the hair cuticle.

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 study found that their system effectively supports the rapid formation of human hair follicle organoids, providing a platform for studying hair regeneration and drug screening.

This study demonstrates that Rac1 activity is essential for normal hair follicle formation but influences hair structure and pigmentation, in terminal differentiation, through alterations in hair shaft, cuticle, and pigmentation organization.

This study revealed key cellular dynamics and interactions during early embryonic mouse skin development, highlighting complex transitions from precursor states to diverse multilayered structures.

This review reports on the effects of aging on hair characteristics such as pigmentation, growth, and structural properties across genders and ethnicities, highlighting the importance of scalp health and suggesting cosmetic solutions to improve the appearance of aged hair.

This study found that mink pelts with "singe" and "red hip" defects often exhibit split hair tips and altered cuticle structures, which may contribute to their undesired metallic sheen.

This review found that 3D bioprinting significantly advances skin tissue engineering by enabling the creation of complex, patient-specific skin structures, though technological and regulatory challenges persist, particularly in areas like scalability and physiological mimicry.

Gender affects hair and scalp characteristics, with differences in hormone responses, graying patterns, and trace metals.

This study concluded that the 800-nm diode laser is effective in enhancing skin structure and collagen expression via the TGF-β/Smad pathway, suggesting potential for non-ablative rejuvenation.

In this study, ketoconazole treatment successfully cured a dog with erythematous epilation caused by Chaetomium globosum, with new hair growth observed 9 weeks later.

This study found that UV laser-induced fluorescence spectroscopy can effectively differentiate between types of alopecia in patients, showing a high correlation between blood circulation levels and tissue autofluorescence intensity.

The researchers reported that in hairless mice, epidermal cell division orientations and epidermal thickness varied by body site, with dorsal and ear epidermis primarily dividing parallel to the basement membrane, unlike hind paw and tail epidermis.

In this study, researchers observed that the epidermal specializations on the tail scales of Lygodactylus lizards, including sensory organs and specific secretory glands, are fully restored with similar structure and distribution on regenerated tails.
