This review discusses various methods of light-based hair removal and reports no new clinical results, highlighting advances in laser and intense pulsed light technologies used for targeting hair pigmentation.

This review discusses the use of lasers and light sources for hair transplantation and pattern hair loss, noting past issues with CO2 lasers and suggesting further trials for low-level light laser therapy.

This study found that sunlight exposure causes significant structural and chemical damage to hair, including cuticle loss, cortex damage, and discoloration, with water playing a major role in discoloration of brown hair.

This review discusses current and potential approaches using stem cells for treating hypopigmentation disorders like vitiligo but does not present new clinical findings.

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 source outlines various surgical techniques as a potential treatment option for vitiligo, highlighting their usefulness when lesions are resistant to traditional therapies such as topical steroids, calcineurine inhibitors, and biological treatments.

This review highlights exosomes as a promising treatment for skin damage from UV light, infrared radiation, burns, and disorders due to their anti-inflammatory properties, ability to induce macrophage polarization, and acceleration of skin repair and regeneration.

This article reviews the optimal methods for photographic documentation in managing patients with androgenetic or diffuse alopecia and reports no clinical results.

This study suggests that using a dermoscope, a handheld microscope, can effectively help distinguish between Pityrosporum folliculitis and Acne vulgaris by revealing unique lesion characteristics that are not visible to the naked eye, offering a practical diagnostic alternative when KOH examinations are unavailable.

This study introduces a new intracavity frequency modulation technique for tunable picosecond optical parametric oscillators, enhancing chemical contrast in coherent Raman imaging by allowing real-time subtraction of background signals.

This study examined 50 patients with alopecia areata and found that trichoscopy can identify specific patterns, such as white dots in 90% of cases and black dots in 80%, aiding in assessing disease activity and severity without invasive procedures.

The study observed that consuming Pflorida soup, made from UV-exposed oyster mushrooms, maintained significant vitamin D levels comparable to recommended daily intake, despite storage and cooking reducing the vitamin content.

Reflectance confocal microscopy is a useful, non-invasive tool for diagnosing some skin diseases, with potential for future improvements.

This review discusses the application of photodynamic therapy for treating oral lichen planus and indicates its potential benefits, but it reports no new clinical results.

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

This study observed that two patients treated with interferon α-2b and ribavirin for chronic hepatitis C experienced complete and reversible straightening of their natural curly hair, which recurred with treatment resumption.

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.

In this study, a new shading model for hair was developed that better matches real-life light scattering, thanks to detailed new measurements of hair fiber scattering not predicted by existing models.

This study introduced a new hair shading model that more accurately simulates light scattering on hair fibers, capturing effects not predicted by previous models.

This review found that many low-level light therapy studies report beneficial effects but often fail to provide adequate measurement details, affecting the reliability and repeatability of the research.

In this review, the researchers highlight LED therapy as an emerging and safe treatment for skin inflammatory conditions, aging, and hair growth disorders, noting its integration into dermatological practice but emphasizing the need for more controlled studies to confirm its efficacy.

This review discusses the diverse applications of low-level laser therapy in aesthetic dermatology, especially for managing alopecia, but notes that comprehensive literature on its effectiveness is lacking.

This study found that near-infrared LED therapy enhanced ATP synthesis, reduced reactive oxygen species, and promoted collagen production and hair growth more effectively than white LEDs in human skin cells and a photoaging mouse model.

Low-Level Laser Therapy can stimulate healing and cell function, potentially leading to wider medical use.

This review compares the CO2 and Er:YAG laser treatments for acne scars, noting that while CO2 lasers offer deeper tissue penetration for severe scars, Er:YAG lasers pose a lower risk of post-inflammatory hyperpigmentation, and recommends personalizing treatments and considering combination therapies.

This article reviews the growing trend of at-home laser and light devices for treating conditions like acne, hair removal, and psoriasis, emphasizing their popularity and the need for cautious use but reports no new clinical results.

The conclusion is that a new method to measure hair shine was confirmed to match people's visual assessments.

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

This study found that red light exposure significantly enhanced the growth, phytochemical content, and therapeutic potential of Eclipta alba callus cultures compared to other multispectral light exposures.

Isolated patchy heterochromia with pili annulati can occur without other health issues.
