This article reviews optimal patient selection and donor site quality for successful hair transplant procedures, but reports no new clinical findings.

This study reports that the TrichoScan method effectively measures hair growth parameters and detected significant improvements in hair counts and thickness in men with androgenetic alopecia after finasteride treatment.

This study introduced a high-viscosity epoxy photoresist to enhance the fabrication of complex microstructures with monolithic integration and mechanical stability, enabling advancements in two-photon 3D printing for creating functional micro-mechanical devices.

This study reported that using photomnemonics facilitated accurate histopathologic interpretation of horizontal scalp sections in distinguishing between nonscarring and scarring alopecias by dermatopathologists and residents in a validation test.

This article describes various hair and scalp examination techniques, including noninvasive, semi-invasive, and invasive methods, noting that trichoscopy is a simple, well-accepted, noninvasive technique for evaluating hair loss patients and monitoring treatment.

This study introduced a new high-throughput method for analyzing scalp hair morphology and found that quantifying hair form provides more accurate information than traditional classification based on racial categories, challenging the belief that cross-sectional morphology predicts hair curvature.

This article discusses tools for measuring hair density in donor areas to guide hair transplant surgery and reports no new clinical results; the authors emphasize the role of digital imaging in achieving consistent outcomes.

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.

In this study, a system was developed utilizing advanced image processing to analyze hair and scalp conditions, aiding professionals in diagnosing diseases like alopecia and monitoring treatment by extracting and comparing key parameters from microscopic images.

This paper details a method for measuring testosterone metabolism into seven androgens using digital autoradiography, which offers high sensitivity and reduces the need for radioactive materials.

In this study, researchers validated a software-based method that quantitatively assesses the effectiveness of treatments for hair loss by calculating the area of hair loss using contrast in standardized photographs, proving effective for both early and advanced cases of androgenetic alopecia and telogen effluvium.

This article describes the immunofluorescence tomography method to achieve high-resolution 3-D reconstruction of epithelial tissues and reports no clinical results.

This study found that Follicular Maps, derived from trichoscopic images, remained consistent over time and unaffected by hair cycling or noncicatricial alopecia, offering a precise tool for diagnosing and monitoring hair and scalp conditions.

This review discusses the advantages and limitations of various hair loss evaluation methods but reports no new results; it emphasizes the importance of cautious interpretation for these diagnostic tools.

This study concluded that including intermediate hairs or using relative shaft diameter methods can significantly improve the sensitivity of trichograms in diagnosing female androgenetic alopecia, aligning better with histopathology results.

This article discusses using the ImageMeter mobile app to calculate scalp area for PRP treatment in androgenetic alopecia, reporting no new clinical results.

The digital system for measuring melasma shows promise but needs more development for better accuracy and automation.

This study demonstrated that a single multimode fiber can be used for single-shot wide-field reflectance imaging, achieving high correlation with the ground truth and enabling real-time microendoscopy at up to 180 frames per second.

In this study, researchers suggest that digital microscopy using visible light could offer a more objective approach to diagnosing hirsutism by quantifying terminal hair, with future research needed to assess its usefulness in women with the condition.

This study found that trichoscopic digital imaging is a safe and accurate method for assessing the donor area in patients undergoing hair transplantation, helping to plan graft utilization based on hair density and follicular unit measurements.
