This review discusses low-level laser therapy and fractional laser therapies as alternative treatments for androgenetic alopecia, but reports limited evidence of their efficacy due to small sample sizes and potential study biases.

This systematic review found that light and laser therapies, including excimer and erbium-glass lasers, generally increase hair density and diameter in various types of alopecia, with particularly notable effects in androgenic alopecia but limited efficacy in telogen effluvium.

In this study, researchers evaluated the efficacy of a collagen booster used alongside CO2 fractional laser treatment for skin aging, finding that the combination treatment affected the vascularization and healing process of the skin on a healthy adult's forearm.

Laser treatment is safe and can effectively treat toenail fungus, especially when combined with other treatments if no improvement is seen after about a year.

In this study, the use of wellness apparel emitting red and NIR light was associated with improved disease severity in patients with mild elbow psoriasis, PMLE, and limited AA, though the small sample size and continued use of other treatments were noted as limitations.

This study describes a new intravital microscopy method for observing intestinal regeneration by tracking crypt dynamics in living mice after laser-induced tissue damage, revealing events like crypt fission, fusion, and disappearance over multiple weeks.

This study employed a laser-based method to analyze how light reflection patterns vary on human hair fibers, revealing changes related to hair color and the tilt of the cuticle cells.

In this study, silver oxide-based nanoparticles were used to ionize analytes and detect specific target molecules through adduct formation with silver isotopes, facilitating signal correlation with these molecules.

Carbon dioxide laser treatment effectively removed facial hair cysts without scarring or them coming back.

This study found that adding a 5 W CO2 laser to an Er:YAG laser improved hemostasis without significantly affecting mean hair counts or increasing lateral thermal damage in men with androgenetic alopecia.

This review found promising benefits of platelet-rich plasma for treating ocular surface diseases in animals, but methodological flaws currently preclude recommending it as standard care.

This review suggests that fractional CO2 laser treatment may be a promising option for treating alopecia areata with a good safety profile.

This review discusses the potential enhanced effectiveness of combining Eflornithine cream with laser or light-based systems for facial hair removal and emphasizes the need for safer and more satisfactory solutions.

In this study, both excimer light and low level light therapy were found to be safe and effective for treating alopecia areata, with excimer light showing better and more sustained improvement.

In this study, Nano-Pulse Stimulation Therapy successfully cleared up to 91% of melanoma tumors in mice with less skin damage compared to cryoablation, which cleared up to 66% of tumors.

This book reviews the evolving use of radiofrequency in aesthetic medicine and its comparison with laser and surgical approaches, but it reports no new clinical results.

This study concluded that fractional laser therapy, alone or combined with minoxidil or cortisol, effectively treated alopecia areata, showing better outcomes than the drugs alone, without increasing adverse effects, though effectiveness did not significantly differ from similar physical treatments.

This review discusses the use of platelet-rich plasma in cosmetic surgery, highlighting its expanding applications and promising potential in aesthetic treatments, but reports no new empirical findings.

This review summarizes clinical and comparative trials on platelet-rich plasma in dermatology and concludes that while PRP shows significant improvements, more randomized controlled trials are needed to confirm its effectiveness for widespread use.

A 5-year-old girl with a rare skin disorder was effectively treated with skin creams instead of oral medication.

Low-level laser therapy may increase hair density in pattern hair loss.

This study found that red OLED irradiation can significantly promote hair regrowth in mice, increasing hair length by 1.5 times and hair regrowth area by over 3 times after 20 days of treatment.

This study found that low-level laser therapy may reduce inflammation and increase hair thickness in patients with lichen planopilaris after six months of treatment, though the small sample size limits the findings.

This study reports that using laser microdissection to isolate telogen hair follicles significantly improves DNA extraction efficiency for STR typing, reducing contamination from keratin.

In this study, researchers observed that red and red-orange LED light therapy stimulates nitric oxide production and decreases dihydrotestosterone synthesis in cell models, suggesting a potential mechanism for using light therapy to treat androgenetic alopecia.

This review discusses the potential role of platelet-rich fibrin in aesthetic and dental procedures but highlights the need for more rigorous future studies to confirm its effectiveness and safety.

The study discusses using red light therapy for hair regrowth, noting red light alone may aid non-inflammatory hair loss, while infrared-red light combination is necessary for conditions like alopecia areata.

This study identified common and unexpected adverse events associated with ritlecitinib in real-world use, providing insights into its safety profile for treating severe alopecia areata.
