Telogen effluvium is a condition that causes temporary hair loss due to stress or shock to the body.

This study found that both 5-ALA and Photofrin can effectively destroy human microvascular endothelial cells in vitro and cause tissue necrosis in vivo, with Photofrin showing greater efficacy at lower concentrations or power densities.

This study reports that melanocytes form a defined photoresponsive network in the skin that reads environmental light cycles and may influence the sleep-waking cycle similar to the pineal gland.

This article reviews the dermatologic conditions associated with hemodialysis, such as pruritus, xerosis cutis, and skin infections, and does not present new findings.

This study found that extracting RNA from equine hair follicles can effectively identify 24-hour oscillations of specific circadian clock genes, offering a valuable non-invasive method to evaluate the equine circadian clock.

This study found that the Hair660™ low-level light therapy device significantly improved hair density and was safe for men with androgenetic alopecia over 24 weeks.

This study found that low-level laser therapy (LLLT) may enhance hearing recovery after noise-induced hearing loss in rats.

This study found that using a Picosecond IR Laser (PIRL) on mouse skin led to less tissue damage and scarring compared to conventional surgical lasers and tools.

In this research, low-fluence light-based hair removal was explored, revealing its potential for at-home use with improvements in efficacy and safety, particularly for dark skin individuals, although further studies are necessary.

Fractional infrared technology is effective and safe for treating cervical laxity.

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.

The ILDS Newsletter reported on efforts to support albinism patients in Tanzania and dermatological conferences.

This study found that while 450nm blue light can inhibit collagen and induce oxidative stress in dermal fibroblasts, 850nm near-infrared light may enhance metabolic activity without causing oxidative damage, suggesting potential for tailored light therapies in skin treatments.

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 abstract lists topics and hypotheses related to vitiligo and associated conditions but does not report any new research findings.

Telogen effluvium causes sudden hair loss, often due to stress or changes, and is treated by addressing the cause and offering support.

This study found that low-level light therapy was as effective as 5% minoxidil for increasing hair density in men with androgenetic alopecia over six months.

This review discusses the effects of low-level laser therapy in various biological processes for wound healing and tissue repair and reports no new results.

This study found that photodynamic therapy using 5-aminolevulinic acid or methyl aminolevulinate is a safe and effective treatment for acne vulgaris, particularly with 30 to 60 minutes of contact time and three treatments for significant long-term improvement.

This study found that careful light microscopy using fluid-mounted hair improves detection of the pili annulati phenotype, which varies widely in expression and affects hair fragility.

This source explores melatonin's roles beyond circadian rhythm regulation, reporting its benefits in skin conditions like dermatitis, melasma, alopecia, psoriasis, and skin aging due to its antioxidant, anti-inflammatory, and immunomodulatory properties, while highlighting the need for more trials on optimal dosing and long-term safety.
