This study found that Notch-related genes, including Notch1 and Notch2, and their ligands and regulators, have distinct patterns of expression during mouse hair vibrissa follicle development and the adult hair cycle.

This review outlines the steps of contemporary hair transplantation surgery, including the roles of medications and nonsurgical options, but it reports no new clinical findings.

This article discusses techniques for creating natural-looking hairlines in hair restoration surgery and reports no new clinical results.

This study found that α3β1-integrin is crucial for maintaining normal hair follicle morphology in mice, as its deficiency leads to severe abnormalities despite not affecting interfollicular epidermal differentiation.

This review describes an improved scalp reduction technique that removes two to three times more bald skin than previous methods, utilizing wide undermining, serial relaxing incisions, and adrenocorticosteroids.

In this study, a methanol extract of Eclipta alba was found to have dose-dependent hair growth-promoting activity in C57BL6 mice.

In this study, mouse amnion epithelium was successfully transformed into skin and hair follicles when associated with hair-forming dermis, revealing the necessity of specific influences for follicle formation.

This study found that mini-micrografting and plug methods achieve comparable hair density, but mini-micrografting requires fewer sessions due to its dense graft packing.

This review examines controversies in hair transplant surgery, including donor harvesting techniques and the roles of platelet-rich plasma and low-level light therapy, and reports no new clinical results.

This study classified hairline contours in Asian women and concluded that their refined hair transplantation techniques may help correct wide foreheads with M-shaped or rectangular hairline contours.

This article reviews expert opinions on combining pharmacologic treatments like minoxidil with hair transplantation, reporting improved hair density and regrowth in patients with partially functioning follicles.

The authors concluded that dermal white adipose tissue, influenced by factors like light irradiation, plays a significant role in modulating hair follicle cycles and could be targeted for hair growth treatments.

This review discusses the structure and regenerative potential of hair follicles, highlighting their role in wound healing, stem cell populations, and keratin-based biomaterials, but it reports no new clinical results.

This article reviews modern hair transplantation techniques, noting that while many innovations have improved natural-looking results and expanded candidate eligibility, some may have hidden drawbacks, and it reports no new results.

In this study using genetic mouse models, researchers discovered that senescent melanocytes in nevi secrete osteopontin, which activates hair stem cells, enhancing hair growth; this process is mirrored in human hairy nevi, suggesting a potential therapeutic target for regenerative disorders.

This study demonstrated that PEGDA hydrogel microwells successfully supported cell survival and proliferation while mimicking hair follicle architecture in vitro, suggesting a potential tool for hair follicle engineering.

This study reported that follicular unit extraction using nonhead hair sources like the chest or beard may successfully restore hair density and achieve aesthetically pleasing results in severely bald men with limited head donor hair.

This article explores factors in designing a personalized hairline, favoring a flared design approach, and reports no new evidence.

This study reports that a robotic device effectively harvests hair follicles with a 95.1% yield in Korean patients undergoing hair restoration surgery.

This study found that preserving hair micrografts in an enriched storage medium for five hours significantly increased their survival rate compared to those stored in saline.

No link found between new male baldness genes and female hair loss.

This review discusses various approaches to treating alopecia, including drug therapy and hair transplantation, but reports no new research findings; the authors highlight the need for novel techniques like cell culturing.

This paper reviews recent research on hair graying, suggesting that an imbalance in oxidative stress handling may affect melanocyte stem cells and melanin production with age, and calls for exploring strategies to prolong melanin production.

This article discusses patient selection and procedural design for hair transplant surgery without reporting new clinical results; it also considers how hair transplant designs can align with various hairstyles.

This article discusses the use of hair transplantation as a reconstructive method to restore hair in various areas affected by defects, highlighting its advantages in providing natural-looking restoration.
