This study found that using a low-level light therapy helmet device daily for 24 weeks improved hair density and thickness among participants, though it did not significantly impact sebum secretion or erythema index.

This review discusses the development of IPL devices, highlights their established cosmetic uses, such as treating vascular and pigmented lesions, and suggests potential expansion into more effective combination therapies.

This review discusses laser/light treatments for pattern hair loss and reports no clinical validation of current devices; experts recommend physician evaluation to exclude other medical conditions.

This study observed that adding low-level light therapy with the GentleWaves® device to Minoxidil significantly boosted hair regrowth in men with androgenetic alopecia by reducing scalp inflammation.

This review discusses the effectiveness of non-thermal, non-ablative devices like light-emitting diodes in treating various skin and hair conditions but reports no new clinical findings.

This study reported that the new near-infrared LED device showed significant improvements in skin rejuvenation and a slight increase in hair growth, with further research recommended for broader validation.

This article reviews non-surgical hair loss treatments and procedures, highlighting options like minoxidil, DHT inhibitors, and laser light therapy, and reports no new clinical findings.

This study presented a new wearable textile-based device with near-infrared OLEDs that significantly reduced cell aging markers and improved cell migration in vitro, suggesting it as a promising, non-invasive phototherapy option for hair follicle treatment and hair-loss management.

This study found that combined intense pulsed light and low-level light therapy significantly improved ocular surface outcomes and quality of life for patients with meibomian gland dysfunction and dry eye disease.

This study found that lasers and light devices may alleviate recalcitrant skin side effects in cancer patients treated with EGFR inhibitors, offering an alternative for those who do not respond to traditional therapies.

This study found that laser hair removal is optimal for light to moderate skin tones using 10-15 J/cm² at 755 nm and for dark skin with 4.5-10 J/cm² at 755-1064 nm.

This study examines the effects of excessive or prolonged exposure to blue light on retinal function and highlights its potential health implications, noting that both photoreceptor and intrinsically photosensitive retinal ganglion cells (ipRGCs) are particularly sensitive to blue wavelengths.

Radiofrequency devices effectively tighten skin without surgery.

This article reviews the use of light-based technologies for hair removal, detailing different laser systems and treatment protocols, but reports no new clinical results.

This study found that UVA blocker-containing sunscreens instantly reduced follicular fluorescence due to porphyrins in facial skin, with the effect lasting for a few hours, influenced by sunscreen amount and formulation.

This review discusses cases and research on paradoxical hair growth after laser hair removal and explores laser and light therapies for treating alopecia, but reports no new results.

In this study, blue light therapy at a specific wavelength increased hair density and shaft width in 90% of patients with androgenetic alopecia after 10 weeks.

This study reported that four patients with lichen planopilaris showed dramatic improvement, including symptom reduction and hair regrowth, after treatment with low-level light therapy.

This study reports that using LED polarized magnification in hair transplant recipient sites can reduce eye strain and improve ease of site creation, but offers no graft placement advantage over traditional methods.

HEV light can harm or help skin and scalp, so safe exposure guidelines are needed.

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

This study found that the HairMax LaserComb® significantly increased hair density and was safe and well tolerated for treating androgenetic alopecia in men compared to a sham device.

This study found that low-level laser therapy significantly increased hair growth in women with androgenic alopecia, achieving a 37% greater increase in hair counts compared to placebo.

This review discusses the mixed evidence and high risk of bias in studies on low-level light therapy for treating androgenetic alopecia and calls for rigorous randomized controlled trials to assess its efficacy.

This article introduces a series on low level laser light therapy, focusing on its science, regulatory aspects, and controlled trial methodologies, but reports no new clinical results.

This study reported that a 3D-printed LED photobiomodulation device is technically and financially feasible, but requires further experimental and clinical testing before being used in human healthcare.

The researchers developed a new follicular unit extraction system with adjustable needle lengths and precise rotation speed, which they report as being superior to existing systems for non-incisional hair transplants.

This review discusses the application of low-level light therapy for hair loss treatment, particularly androgenetic alopecia, and reports no new clinical results; the authors suggest consideration of light source characteristics and potential pros and cons.

This review discusses the potential mechanisms and evidence supporting low-level laser therapy for stimulating hair growth in men and women, while noting its safety and effectiveness but needing further study on specific parameters.

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.
