In this scoping review, researchers observed that while AI-assisted trichoscopy holds promise for standardized assessments of hair and scalp disorders, its clinical translation is limited by small proprietary datasets, inconsistent validation protocols, and a scarcity of real-world clinical studies.

This review discusses the essential qualifications and considerations for safely performing hair transplantation, including training, facilities, and patient selection criteria, but reports no clinical results.

This article discusses various issues and controversies in hair transplantation, including ethical considerations, the debate between follicular unit transplantation and excision, the concept of a safe donor area, the use of platelet-rich plasma, and the minimum qualifications needed for practitioners.

This article discusses various affiliations of the authors with no reference to new research findings.

This study found that body hair transplantation using follicular unit extraction was effective and resulted in high satisfaction among selected patients with limited scalp donor hair.

In this study, a curved nonrotary punch was found to achieve the lowest follicular unit transection rates of less than 5% compared to conventional rotary punches in hair transplantation for patients with tightly curled Afro-textured hair.

In this study, transplanted hair follicles from different body sites showed changes in morphology and immune status, suggesting their ability to adapt and function in new recipient areas such as the scalp or eyebrows.

This article discusses the benefits, techniques, and unique considerations of follicular unit extraction for hair grafting, but reports no new clinical results.

This review discusses the methodology, limitations, and advantages of Follicular Unit Extraction in hair transplantation without providing new clinical results.

This study found that hair transplant surgeons can use a new model to predict the number and distribution of follicular units in donor scalp areas based on patient hair density.

This study revealed that in androgenic alopecia, the proximal attachment of the arrector pili muscle to the hair follicle is often lost or significantly reduced.

This study found that photoacoustic imaging can effectively measure follicle density and angles, even when follicles are not visible to the eye, providing a promising alternative to traditional photographic examination.

Combining FUE hair transplantation with PRP improves hair density and patient satisfaction in scarring alopecia.

This study examined the follicular unit density in the scalp and beard donor areas of Indian men undergoing hair restoration surgery, reporting mean densities of 78.2/cm² and 49.7/cm² respectively, and proposed guidelines for safe follicular unit extraction.

This study found that polymeric micelle nanocarriers delivered pharmacologically relevant amounts of spironolactone to the epidermis and upper dermis, with higher delivery to pilosebaceous units, suggesting potential for treating glucocorticoid-induced impaired wound healing and pilosebaceous androgen-related skin diseases.

Results are not reported in this invited commentary, which discusses the benefits of proper hair restoration as addressed by Jeffrey Epstein in JAMA Facial Plastic Surgery.

Using a buffering solution and applying Platelet-Rich Plasma improves hair graft survival in hair restoration surgery.

This study observed that autologous platelet-rich plasma treatment improved hair count and density in areas with androgenetic alopecia compared to placebo, with differing outcomes based on the PRP collection device used.

This article discusses using body and beard hair for hair restoration and reviews the indications, techniques, and risks involved, but reports no new clinical results.

This study found that platelet lysate produced higher follicular regeneration in hair restoration surgeries compared to activated PRP and saline, with significant gains in both follicular unit and hair density.

This study found that 2-hair follicular unit grafts were the most common grouping in hair transplant procedures, with frontal edema as the most frequent postoperative complication.

This study found that eyebrow transplantation, when performed with meticulous technique and innovative approaches to address donor density and hair angle issues, resulted in high patient satisfaction and aesthetic outcomes, with a low complication rate.

Achieving original hair density with transplants is unrealistic; skilled practitioners are essential for the best results.

This review discusses the use of follicular unit extraction for hair restoration, particularly body hair transplantation, and highlights its potential as an alternative donor source in advanced baldness cases, but reports no new clinical findings.

Various techniques and tools for hair restoration were presented in 1998, including a mathematical model for donor area, use of lasers in surgery, methods for controlling grafted hair direction, and ways to increase graft yield. Satisfaction rates were around 39%, and studies showed trauma and dehydration can damage hair follicles.

This review discusses the advantages of robotic hair transplantation using the ARTAS iX robot compared to manual Follicular Unit Extraction, emphasizing enhanced precision, speed, and hair preservation capabilities, and reports no clinical results.

Experts discussed sedation, hair transplant techniques, and called for respectful professional communication.

PRP might help with hair growth and skin rejuvenation, but more research is needed to prove its effectiveness.

This correspondence discusses issues related to overharvesting and challenges in measuring factors that impact donor coverage in hair transplantation procedures, but it does not report specific study results or outcomes.

People with X-linked hypohidrotic ectodermal dysplasia have no sweat ducts and less, thinner hair.
