A young man was unexpectedly diagnosed with basal cell carcinoma after a scalp examination and confocal microscopy.

This article highlights that tinea capitis, a fungal scalp infection primarily seen in children, is often misdiagnosed in adults, especially postmenopausal women and immunocompromised individuals, leading to unnecessary treatments and potential permanent hair loss if not correctly identified and treated.

This report describes two cases of tinea capitis in young siblings, with cultures showing M. canis and Rhodotorulla, and notes improvement after treatment with ketoconazole lotion and shampoo for two months.

This study found that micro-computed tomography (micro-CT) was highly effective for analyzing the cross-sectional geometry of hair fibres, including the medulla in highly curled hair, but less effective than scanning electron microscopy for surface details.

This study concluded that bleach treatment partly transforms the hydrophobic top layer of human hair cuticles into a hydrophilic surface with clustered cysteic acid, visualized at the nano-scale using dynamic Chemical Force Microscopy.

This study developed new graded visual scales integrating macroscopic and trichoscopic images for assessing the severity of androgenetic alopecia in men and women, potentially aiding in more objective disease evaluation.

This study reports that different animal species exhibit distinct hair scale patterns and elemental compositions, which can aid forensic investigations in identifying animal hair.

This article discusses the use of a high-magnification digital video microscope for diagnosing and treating androgenetic alopecia and reports no new clinical results.

This study found that clinically non-affected perilesional scalp in Japanese alopecia patients often showed microscopic abnormalities, which may help in assessing the spread of disease activities.

This study found no significant difference in the tensile properties of hair from different scalp positions, suggesting that microscopic structural heterogeneities may play a role.

This study used air wedge interferometry to measure the thickness of human scalp hair from three individuals, finding average thicknesses of 66.482 µm, 59.355 µm, and 59.927 µm respectively, within the typical range for adults.

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 case report describes a 7-year-old boy with pityriasis versicolor presenting as scalp hypopigmentation, a rare distribution for this fungal infection. Diagnosis was confirmed via Wood's lamp examination and microscopy, and the condition resolved after treatment with topical terbinafine hydrochloride cream.

This case report describes successful treatment of a 7-year-old girl with gray patch tinea capitis using oral micronized griseofulvin and topical ketoconazole shampoo, resulting in complete clinical and microscopic clearance.

This study developed a model using homogenization-based framework to quantify solvent and solute flow across Janus membranes, aiming to better understand interface phenomena like osmosis and phoresis by examining micro- and macro-scale behaviors.

Examining scalp tissue under a microscope helps diagnose and understand hair loss diseases.

This study found that in naturally curved human scalp hairs, distinct arrangements of cell types on either side of the hair fiber contribute to its curvature.

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 case study reported normal hair structure under polarized light microscopy in a 70-year-old man with zinc deficiency, contrasting with previous findings in acrodermatitis enteropathica.

In this study, Kerion Celsi, a deep fungal scalp infection, is highlighted as being rare in neonates but more common in children over 3 years, requiring medical treatment with antifungals and antibiotics to prevent scarring alopecia and distinguish it from bacterial infections.

This study describes how arrector pili muscles form a single muscular structure shared by all hair follicles within a follicular unit at the isthmus level in scalp skin.

This study observed that in chicken skin, large-scale differences in gene expression between feathered and scaly skin are controlled by enhancer-driven uniform expression, while small-scale differences within individual feathers are associated with chromatin looping.

This study found that polarized light microscopy is more effective than diffractive microscopy in distinguishing scarring from non-scarring alopecia, providing a highly specific adjunct diagnostic tool for alopecia biopsy specimens.

This study shows that multiphoton microscopy can non-invasively distinguish scarring from non-scarring alopecia by identifying specific morphological features in hair follicle structures.

A 4-year-old girl had a rare hair disorder affecting only part of her scalp.

This paper discusses the use of dermatoscopy as a fast, noninvasive technique for diagnosing hair shaft disorders and reports no new results; the authors highlight its advantages over traditional microscopy methods.

This study discovered previously unknown structures in human hair shafts that may stabilize hair structurally and physicochemically.

In this study, 13 androgenetic alopecia patients receiving Er: Yag laser treatment showed a significant increase in Staphylococcus spp. three days post-treatment, suggesting the laser may help modulate scalp microbiota balance.

In this study, researchers found that using a handheld digital microscope, hair diameter was a better determinant of perceived alopecia severity in androgenetic alopecia than hair density.

This review discusses the diagnosis and characteristics of dermatophyte infections and offers no new research findings, emphasizing the importance of microscopy and culture for accurate identification before treatment.
