This study found that VEGF significantly enhances perifollicular vascularization during the hair growth phase, accelerating hair regrowth and increasing follicle and hair size, while its inhibition retards hair growth.

This overview describes the Dermatologic Surgery journal's extensive coverage of cosmetic and reconstructive skin surgery, but it reports no new research findings.

This review provides an overview of how advancing imaging technologies, such as tissue clearing and intravital microscopy, are enhancing our understanding of tumor architecture and interactions between cancer cells and the tumor microenvironment, aiding both fundamental cancer research and the development of therapies.

This paper introduces a novel approach to simulate hair dynamics by modeling hair volume as a continuum, effectively treating interaction dynamics as fluid dynamics for realistic hair animation rendering.

This study describes a system called FOLLYSIS©, which uses mathematics and image analysis to optimize Follicular Unit Extraction hair transplants, showing high accuracy in measuring donor area density and reducing donor site injury.

This review study found that vesicular carriers like liposomes, niosomes, invasomes, and transferosomes can enhance drug penetration through follicles, benefiting treatments for alopecia, acne, and infections, as well as potentially facilitating systemic delivery of antihypertensive drugs and insulin.

This paper reflects on the challenges and progress in hair restoration, highlighting ongoing efforts for improvement but providing no new empirical findings.

This study reports that a single transplantation of autologous stromal vascular fraction significantly increased hair density and keratin score in androgenic alopecia patients within six months.

Tumescent local anesthesia is a safe, cost-effective method for outpatient liposuction.

In this controlled study, a 6-month treatment with the nutraceutical product ViviScal® reduced telogen hair fibers and increased total hair fibers in 83% of participants with Telogen Effluvium, who also reported improved hair and nail growth, skin appearance, and overall quality of life.

This article discusses advancements in hair restoration surgery techniques and does not provide new research findings.

In this study, two male patients with androgenetic alopecia who had previously undergone hair transplants showed increased hair regrowth after receiving verteporfin injections, with a 63% mean increase in dense donor sites, 38% in thinning areas, but no growth in bald areas.

This study reported significant improvements in hair density, diameter, and patient satisfaction after using non-enzymatic stromal vascular fraction treatment for androgenic alopecia over six months.

This study found that the combination of recombinant growth factors and plant-derived extracellular vesicles significantly improved scalp regulation, hair growth, thickness, and density, and reduced hair shedding in the tested formulation by Day 56.

This article describes a procedure involving skin marking, tumescent anesthesia, and micrograft mobilization, but does not present any study findings or results.

This study found that cationic lipid-based formulations enhanced the delivery of large molecules into hair follicles in human scalp skin, with potential to reach pharmacologically active concentrations in the hair bulb.

In this study, researchers introduced an ultrasound-guided technique for injecting hyaluronic acid fillers into the temple area to enhance safety and precision by visualizing filler placement in the interfascial space.

This study found that multiparametric ultrasound effectively detects real-time scalp changes caused by vasoconstrictive cosmetic agents, demonstrating its potential as a non-invasive tool for evaluating trichological treatments.

This chapter reviews the clinical evidence of adding platelet-rich plasma to lipofilling for tissue regeneration, with suggestions of benefits in skin rejuvenation and wound healing, but lacks well-designed trials.

This study reviewed cases of filler-induced alopecia and found that hyaluronic acid injections were most commonly associated with this condition, highlighting that hyaluronidase treatments can rapidly restore hair density, while alternative interventions need further exploration.

This study found that electronically-operated pneumatic injections for administering a peptide-hyaluronic acid combination were well tolerated and led to significant improvement in hair density and thickness for men with androgenic alopecia over six months, though the exact mechanism remains uncertain.

This article discusses the importance of understanding hair direction and angulation in hair restoration but reports no new experimental findings.

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 study found that combined platelet-rich plasma injections and suture embedding significantly improved scalp thickness, blood flow, and hair diameter in patients with androgenetic alopecia.

This article reviews methods such as stem cell implantation to enhance hair transplant donor supply but reports no new clinical findings.

In this study, a treatment combining fractional 1927nm laser with a growth factor serum was found to increase hair density and diameter in patients with androgenic alopecia over six months, without side effects, and three treatments at 4-weekly intervals were deemed most effective.

This study reported that a single-session scalp procedure combining several components, including PRP and botulinum toxin, was associated with significant improvements in hair thickness and reduced vellus hair proportion in androgenetic alopecia patients, although further controlled trials are needed to establish causation.

In a study on the effects of stromal vascular fraction (SVF) and platelet-rich plasma (PRP) on hair growth in nude mice, researchers found that both treatments promoted hair growth, with SVF showing a stronger effect.

In this study, researchers developed a biomacromolecular hydrogel to deliver plant-derived extracellular vesicles for treating androgenetic alopecia in a mouse model, which significantly improved hair regrowth and follicle density by activating Wnt/β-catenin signaling.

This review covers the extensive range of aesthetic and reconstructive surgery detailed in Volumes 2 and 3 of "Plastic Surgery," highlighting its comprehensive and well-organized content but reports no new clinical results.
