This article presents a comprehensive overview of hair microscopy techniques and their diagnostic potential for systemic and cutaneous disorders, emphasizing its usefulness in resource-limited settings and highlighting the underutilization of this non-invasive method due to lack of awareness.

This study found that hair from the vertex posterior is a reliable sampling region for detecting zolpidem intake, showing consistent drug concentration and peak position compared to other scalp regions.

Home photobiomodulation therapy can improve life quality and mobility for disabled individuals.

This study observed that bacterial communities on scalp hair collected through non-invasive swabbing showed similar diversity and composition to those obtained by cutting or removing hair, suggesting that swabbing is an effective method for microbiome analysis on hair.

This study suggests that newly developed micro-pigment-encapsulated biodegradable microneedles accurately implant pigments in pig cadaver skin, potentially advancing scalp micro-pigmentation methods.

This study found that patients who received photobiomodulation therapy after septoplasty experienced lower pain levels and improved heart rate variability compared to those who underwent standard postoperative management alone.

Scalp hair grows at 0.37 mm/day, forearm hair at 0.18 mm/day, and thigh hair at 0.30 mm/day, with no significant differences found in people with certain hair conditions.

This pilot study explored a new method using laser-capture microdissection and 16S rRNA gene sequencing to analyze the human scalp hair follicle microbiome more accurately, revealing region-specific variations in microbial diversity and abundance.

This study found a perfect correlation between laser Doppler velocimetry measurements of scalp blood perfusion after minoxidil application and sulfotransferase enzyme activity in hair follicles, indicating a potential non-invasive test to predict minoxidil response in female pattern hair loss.

This study found that photoepilation in mice may disrupt normal dermal wound healing and increase the risk of hypertrophic scars or keloids.

Light scatters differently from elliptical hair fibers than from circular ones, and a new model better predicts this behavior, especially for shiny highlights.

Among maize plants, this study observed that root hairs tend to grow in air-filled pores at the root-soil interface, but their growth into the soil matrix is limited, posing potential constraints on nutrient uptake, anchorage, and rhizosheath formation.

This study concluded that intralesional lyophilized growth factor injections are safe and improve trichoscopic hair parameters and clinical scores in patients with female pattern hair loss.

This review discusses the use of trichoscopy for diagnosing alopecia and reports no new clinical results, emphasizing its role in identifying vascular and follicular features.

This study presented a hair harvesting robot with an advanced end-effector that improves accuracy and efficiency for Follicular Unit Extraction, showing a precision of 0.014 mm.

This study concludes that the Greek version of the Dysmorphic Concern Questionnaire is a reliable and valid tool for assessing body dysmorphic disorder-related concerns in both research and clinical settings.

Photobiomodulation did not significantly improve hair density in dogs with alopecia X.

This study found that a new 12-point scale provided a more precise measurement system for evaluating hair damage and improvement after hair care product use compared to a 5-point scale.

This review outlines the practical use of reflectance confocal microscopy in dermatology, detailing its applications and considerations for diagnosing various skin conditions, but reports no new findings.

This study used two-photon microscopy to reveal that the dermal papilla is crucial for hair follicle regeneration and cannot be replaced by neighboring cells, providing new insights into stem cell behavior.

This review discusses pain management strategies for optical permanent hair removal, which causes pain due to the increase in skin surface temperature, but reports no new experimental results.

This study found that the novel dot-block method can effectively measure early- and advanced-glycation products in hair, suggesting its potential for monitoring diabetes progression and other chronic conditions.

This study found that the modified wash test was generally more effective than TrichoScan® for diagnosing hair loss, particularly telogen effluvium, though both methods showed only fair concordance with clinical diagnosis.

The researchers reported that in hairless mice, epidermal cell division orientations and epidermal thickness varied by body site, with dorsal and ear epidermis primarily dividing parallel to the basement membrane, unlike hind paw and tail epidermis.

This study surveyed hairline preferences and found that the M-shaped contour was most preferred overall, with lower forehead heights favored by men and those without a history of hair transplantation.

Trichoscopy helps diagnose and manage different types of hair loss effectively.

Patient-reported hair improvements align with actual hair density changes, not hair width.

This abstract discusses the scalp micropigmentation tattoo technique as a permanent camouflage method, without reporting new clinical results.

This study found that scalp thickness and hair follicle depth were reduced in individuals with androgenetic alopecia, and MRI signal intensity was higher compared to those without the condition.
