This study found that LEDs at specific wavelengths may improve antifungal performance and promote hair growth by activating scalp cells without inducing inflammation compared to a non-irradiated group.

This study found that the Bradford assay is a sensitive and reproducible alternative to the Lowry test for quantifying hair protein loss during brushing, with bleached hair releasing more protein than virgin hair.

This study found that photodynamic therapy achieved permanent removal of nonpigmented hair in mice after multiple sessions, unlike laser treatment, which was not effective for nonpigmented hair.

This review discusses the evolution and potential of photobiomodulation therapy, highlighting its transition from skepticism to recognition in medical research; it reports no new experimental findings.

In this study, a computer-aided imaging system accurately measured the width of balding areas in female pattern hair loss, correlating strongly with clinical staging severity.

This review discusses various methods for measuring scalp hair growth in androgenetic alopecia and reports no new results; the authors suggest that computer-assisted technology has untapped potential.

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.

This paper describes an enzymatic method to isolate hair pigment from the keratin matrix without altering its chemical structure, but it presents no new results.

This study used light sheet fluorescence microscopy to successfully image and analyze calcium oscillations in the root hairs of Arabidopsis thaliana, finding that these oscillations correlate with the root hair growth rate and that auxin affects these properties.

This study found that trichoscopic quantitative parameters reliably indicate the severity of female pattern hair loss and complement the Sinclair scale by offering a more objective and reproducible grading system.

This study suggests that analyzing hair samples with a liquid chromatography-mass spectrometric assay may offer a reliable method to measure average quarterly vitamin D levels, potentially complementing blood tests.

This study introduces a novel method for capturing and digitally rendering the color appearance of physical hair samples using deep neural networks.

This study proposes a new mathematical model, the Harmonic Mean equation, for precisely quantifying nuclear pleomorphism in breast cancer grading, showing high performance with accuracy, recall, specificity, precision, and F1-score metrics.

This study suggests that a prototype device may accurately measure hair quantity, diameter, and density in balding patients, potentially aiding in diagnostic assessments, though formal clinical studies are needed to confirm its effectiveness.

This study found that multiphoton microscopy effectively visualizes the microstructure of in vivo mouse skin, offering a clear view of various skin layers and components like corneocytes and collagen fibers.

This paper discusses the use of Digital Volumetric Imaging with fluorescent dyes to visualize and compare the interior structures of six different virgin hair types, reporting no new clinical results.

This study developed and validated a precise and rapid HPLC method to simultaneously determine Minoxidil and Finasteride in pharmaceuticals, demonstrating successful application for routine quality control without interference from excipients.

Phototrichogram helps assess hair loss severity.

This study found that photodynamic therapy may offer a new option for removing nonpigmented hair, although it was less effective than diode laser for black hair in mice.

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.

QIA-64 software can measure straight wire lengths accurately but needs improvement for curved wires and width measurements.

This study found that human hair follicles demonstrated a dose-dependent response to light in an ex vivo photoepilation model, which could predict the clinical efficacy and permanency of light-based hair removal devices.

This study concluded that the Scalp Photographic Index is a reliable and validated tool for objectively classifying and scoring various scalp conditions.

This study introduces a non-invasive photoacoustic imaging technique that accurately measures hair follicle density and subdermal angles, showing strong correlation with the gold-standard photographic method.

This abstract discusses the pervasive promotion and marketing of plastic and cosmetic procedures, without reporting any new clinical findings.

This article reviews the limitations in current research on photobiomodulation for hair regrowth and suggests that optimal wavelengths and dosing have not yet been identified, noting that recommending these devices may be premature.

This study found that the TrichoScan method detected significant increases in hair counts and cumulative hair thickness in men after finasteride treatment, suggesting its potential for monitoring hair treatment responses.

This review discusses the therapeutic use of photobiomodulation for various skin conditions, highlighting its efficacy in accelerating tissue repair, reducing inflammation, and treating pigmentary disorders and other skin diseases, but it reports no new clinical results.

This review concluded that near-infrared and red light photobiomodulation shows potential for certain ocular conditions like age-related macular degeneration and dry eye disease, but clinical evidence is still mixed and insufficient to establish it as a standard therapy.

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.
