This review evaluates laser therapy for alopecia areata, noting that fractional lasers facilitate hair growth and drug delivery, but reports no new clinical results.

In this study, researchers found that combining fractional CO2 laser sessions with topical dutasteride was more effective in improving male androgenic alopecia than using the laser treatment alone, as observed through global photo assessments and dermoscopic parameters.

Smart microneedles using advanced tech could improve psoriasis treatment.

This article highlights that fractionated laser therapy is gaining attention as a minimally invasive and effective treatment for androgenetic alopecia, offering a potential solution to traditional treatments' limitations.

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 assessed evidence on laser therapies for alopecia areata, reporting that the 308-nm excimer laser showed hair regrowth in several studies, while more research is needed for other laser types.

This study found that the 2,940 nm erbium: YAG laser may promote hair growth in C57BL/6 mice by speeding up transitions in the hair cycle and increasing hair follicle numbers.

Laser and light therapies can help regrow hair but need more research for best results.

This study found that nonablative Er:YAG laser therapy effectively improved hair appearance for patients with androgenetic alopecia, with most participants reporting increased satisfaction and no adverse reactions, following six biweekly sessions.

In this study, both fractional carbon dioxide laser therapy and cryotherapy were found to be effective and safe for treating patchy alopecia areata, showing similar efficacy in improving hair growth compared to untreated control patches.

In this retrospective study, a combined therapy of ablative fractional Er: YAG laser and medication was more effective in treating male androgenetic alopecia than medication alone, without causing serious adverse effects, as evaluated over 24 weeks.

People with hair loss have low zinc levels; zinc supplements and laser therapy may help.

This article reviews various diagnostic tools for hair disorders, describing methods ranging from invasive to noninvasive, but reports no new research findings or clinical results.

This article reviews approaches to facial aging in Asian patients, discussing cultural perspectives and proposing a new paradigm of youthful appearance, but provides no new clinical results.

This study analyzes contemporary theories and practices to understand key factors influencing the development of the examined phenomenon, proposing trends and practical applications for researchers and practitioners, while acknowledging study limitations and suggesting future research directions.

This review summarizes current knowledge on tight junctions in mammalian skin and their role in drug delivery and interaction with other barrier components, but reports no new experimental results.

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.

This review discusses the dermatologic features of PCOS as potential early indicators of the syndrome and notes that treatment of these conditions may enhance quality of life and psychological well-being, but it reports no new clinical results.

This review discusses current knowledge on the biological mechanisms of different types of alopecia but reports no new clinical findings; the authors highlight future research directions, especially regarding epidermal stem cells and immune pathways.

This protocol describes using two-photon laser-scanning microscopy to study hair regeneration in live mice, offering detailed imaging capabilities for observing hair follicle stem cell behavior and manipulating cellular populations.

This case study of a patient with dissecting cellulitis of the scalp found that multiple medications, including isotretinoin, achieved only modest improvement, and symptoms returned after treatments were stopped.

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 review covers nonsteroid-based therapies for alopecia areata, finding potential in PRP, UVR, and laser treatments, but highlights a lack of high-quality evidence for their efficacy.

This study observed that hairless HRS/J mice were resistant to Bacillus anthracis infection at the skin's surface, suggesting resistance may be due to increased dermal neutrophils rather than non-functional hair follicles.

This study demonstrates the use of microscopy-guided laser ablation to create a highly structured 3D hydrogel-based organotypic skin model with folliculoid structures, potentially useful for studying hair follicle development or bioactive substance screening.

This review discusses the role of scalp imaging techniques in trichology for researching drug delivery and toxicology, without presenting new clinical results.

In this study, the researchers observed that inducing and then withdrawing β-catenin expression in a bigenic mouse model caused reversible changes in skin morphology, indicating dependence on β-catenin signaling.

This study found that rubbing significantly increased skin permeation of caffeine but not rhododendrol, with the direction of rubbing playing a crucial role in caffeine's enhancement.

Pulsed dye laser and hydrogel dressings effectively treat hypertrophic scars.

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.
