In this randomized, double-blind trial, researchers observed that low-level laser therapy led to significantly greater hair regrowth on treated areas compared to a sham treatment in patients with androgenetic alopecia over 24 weeks, suggesting it as a potentially effective and safe option.

This study found that in-person photobiomodulation treatments improved hair growth in men and some women with androgenetic alopecia, except for the laser band and combination laser/LED helmet in women.

This review discusses various treatments for noncicatricial alopecias, such as androgenetic alopecia and alopecia areata, including mesotherapy, microneedling, and platelet-rich plasma therapy, noting that outcomes vary across these procedures.

This meta-analysis reported that photobiomodulation therapy may improve hair density and stimulate hair growth in patients with androgenic alopecia compared to sham treatments, but larger studies are needed to confirm these findings.

This review discusses the impact of age-related hair changes on perceived attractiveness and self-perception, emphasizing the need for holistic anti-aging consultations that include hair preservation strategies.

In this preclinical study, researchers developed and evaluated a new non-invasive laser system designed for personalized medical use, showing its potential for chronic disease management and adjunctive fat reduction by offering enhanced treatment precision and adaptability over existing devices.

In this study, the P&P Hairline Laser, a hands-free laser-assisted device, was found to produce smoother and more symmetrical hairlines compared to traditional handheld laser devices.

This observational study reports that a TRASER device using specific wavelengths for vascular and follicular targets showed both clinical responses and histological changes, suggesting its potential as an effective vascular and hair removal tool.

Laser Lax is a new tool that measures scalp looseness accurately and comfortably.

In this study, the researchers demonstrated an automatic alignment method for beams in an electron pumped excimer laser system that achieved high precision and accuracy, with a reported alignment accuracy of 0.63μrad.

This study found that cross beam laser is a reliable tool for assessing scalp laxity in hair restoration surgery, with results comparable to the Mayer elasticity scale.

This literature review reported that fractional lasers, like the 1550-nm nonablative erbium-glass laser, may enhance hair regrowth by stimulating a wound healing process, but more randomized controlled trials are needed to confirm their effectiveness and optimize treatment parameters.

This article discusses the use of laser technology in hair transplantation and highlights its potential benefits and drawbacks, emphasizing its role in achieving natural results in cosmetic hair restoration.

This review summarizes late-breaking abstracts from the American Society for Laser Medicine and Surgery, 2018, and reports no new clinical findings.

This study introduced laser particles as a new imaging probe capable of real-time tracking of thousands of individual cells in 3D tumor models, suggesting potential for advanced single-cell analyses.

This editorial discusses the terminology and distinctions between Low-Level Light/Laser Therapy and Photobiomodulation Therapy but reports no new clinical findings.

This narrative review discusses the evolution and diverse medical applications of laser technologies, particularly in dermatology and skin biology, without reporting new research findings.

This study introduced a novel microscopy system using an Er3 + −doped femtosecond fiber laser, achieving detailed imaging of biological structures in plant and skin samples with improved spatial resolution for various applications, including in vivo imaging.

This study developed a double-wavelength laser scanning microphotometer to measure hair shaft and follicle absorbance, improving spatial resolution and reducing light scattering effects in vitro.

This study suggests that a portable OCT system may be useful for the clinical diagnosis and evaluation of skin diseases and laser treatment outcomes.

This study introduced laser-assisted exosome delivery and observed early signs of clinical improvement in two patients, though causality cannot be inferred from these preliminary, uncontrolled cases.

Lasers in hair transplantation show promise but are not yet standard, with current methods causing some side effects and needles still being preferred for creating recipient sites.

This review found that laser-assisted drug delivery in humans was associated with several adverse effects, but no life-threatening events were reported in the studies examined.

This study found that the dual-wavelength non-ablative fractional laser provides enhanced skin rejuvenation by increasing thermal lesion coverage and collagen remodeling compared to using the CO2 laser alone in an ex vivo setting.

Hair shine can be measured by how it reflects laser light.

This study found that using dual-wavelength low-level laser therapy is more effective for hair regrowth in mice than single-wavelength treatment and significantly better than no treatment, based on 14 days of phototherapy with LED lights.

This study suggests that a 1,550-nm fractional erbium-glass laser may stimulate hair growth in both an alopecia mouse model and human subjects with male pattern hair loss, though further research is needed to determine its clinical applications.
