This review highlights recent advancements in FUE hair transplantation techniques and technologies, noting significant improvements in reducing follicle damage and increasing procedure speed, while emphasizing the need for surgeons to choose suitable devices for each patient's specific needs.

This study found that participation in a training workshop can significantly improve the reliability of evaluating ultrasonographic features of polycystic ovaries, suggesting standardized training modules should be used for consistent diagnosis of PCOS.

This review evaluates androgenetic alopecia treatments, highlighting both current options like minoxidil, finasteride, and low-level light therapy, and emerging therapies such as platelet-rich plasma and complex combination treatments, noting their potential and challenges.

Using three-hair grafts from the back of the head for eyebrow transplantation offers a natural look and reduces scarring.

This review outlines various 3D bioprinting techniques and bioinks used for creating artificial tissues and organs, emphasizing their potential in addressing organ transplant shortages and advancing drug testing, while acknowledging existing challenges and future prospects.

This study examined the Spanish Merino breed's wool quality, identifying 74 genetic variants linked to key wool traits like fiber diameter and staple length, which could help restore the breed's potential for producing high-quality wool.

This case report highlights keloid formation as a rare complication at the donor site after follicular unit extraction hair transplantation, suggesting practitioners should be aware of procedure-associated risks.

This commentary highlights the debate on the role of inflammation and fibrosis in androgenetic alopecia, contrasting various studies' findings without reporting new results.

This review explores animal models of alopecia areata, particularly focusing on the insights they've provided into the disease's immune mechanisms and potential treatment approaches, without reporting new experimental data.

This study found decreased hair density and altered follicular architecture in the balding frontal scalp of patients with androgenic alopecia, with increased vellus hairs noted.

Sulphur in hair follicles increases from the bulb and then levels off, while other elements vary in distribution.

This study observed that adult male raccoon dogs undergo seasonal moults, with winter fur maturing by the end of November after significant hair growth in spring and autumn.

This study observed that pelage development in male blue foxes born in early June was more synchronized than those born in early May, with differences likely influenced by melatonin levels.

This review discusses the need for more research on how the chronobiological control systems regulate hair follicle cycling and reports no new results.

This study used single-cell RNA sequencing to map the cellular composition of sheep hair follicles, revealing differentiation pathways and potential molecular mechanisms for wool curvature, which may inform sheep breeding.

Using a microscope during hair transplants cuts damage to follicles in half and could improve hair growth.
