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

In this study, MSC-laden silk nanofiber hydrogels accelerated wound healing and enabled scarless skin regeneration with hair follicles, outperforming MSC-free hydrogels in repairing full-thickness skin defects.

This study developed the Alopecia Areata Investigator Global Assessment (AA-IGA) to measure scalp-hair loss in alopecia areata patients, incorporating perspectives of both patients and clinicians to define treatment success.

This study found that drug delivery through human scalp skin may be more effective for lipophilic and hydrophilic drugs compared to abdominal skin, highlighting the potential of intrafollicular delivery methods.

This study found that scalp sensitivity frequently occurs in the French population and is associated with various symptoms and triggers, differing from facial skin sensitivity.

This study found that the Verhoeff-Van Gieson stain effectively distinguishes scarred from non-scarred dermis and aids in classifying types of permanent alopecia based on elastic tissue patterns.

This review discusses the experimental targets of fetal wound healing and evaluates existing therapies for scarless healing in adult skin, but reports no new research findings.

This study found that both human and rat dermal papilla spheroids can induce hair follicle neogenesis, but larger spheroids increase inductivity without significantly affecting hair fiber diameter.

This study reports that the ScalpEye system accurately diagnosed dandruff, folliculitis, hair loss, and oily hair with a precision range of 97.41% to 99.09%.

This review explores the hair follicle microbiome's interaction with the immune system, discussing its potential clinical implications for scalp health and disease but reports no new clinical results.

This review discusses trichoscopy as a noninvasive, effective technique for diagnosing various hair loss conditions and monitoring treatment, highlighting its potential to reduce scalp biopsy necessity.

This review examines the role of endothelial precursors and cellularized scaffolds in wound repair and revascularization for treating full thickness skin loss, but reports no new clinical results.

This study reports that permanent and severe alopecia is a newly identified complication of the FEC 100–docetaxel regimen used for adjuvant breast cancer treatment.

This study found that dermoscopy can be a useful tool for diagnosing androgenetic alopecia, particularly in determining hair diameter diversity as an essential feature in Asian populations.

This narrative review discusses the use of micrografts and minigrafts for facial and scalp reconstruction following various causes of hair loss and reports a high level of patient satisfaction with these techniques.

In this study, researchers found that electrospun membranes with aligned surface topography advanced the immune response towards an adaptive stage and highlighted the role of T cells in hair follicle regeneration in mice, showcasing the intricate interactions between immune and skin cells.

This review discusses current techniques for scalp reconstruction following oncologic surgery and reports no new clinical outcomes, emphasizing the importance of tailored approaches for satisfactory closure.

This study observed that dandruff in Indian women is associated with a distinct scalp microbiome, including specific bacterial and unknown Malassezia species, with implications for nutrient homeostasis and cell-host adhesion pathways.

In this study, finasteride doses as low as 0.2 mg per day significantly reduced both scalp skin and serum DHT levels in men with androgenetic alopecia.

This study describes a new condition called scalp dysesthesia in 11 women, most of whom experienced symptom improvement with low-dose antidepressants.

This study found that dermoscopy-guided scalp biopsies provided a definitive pathological diagnosis in 95% of patients with cicatricial alopecia.

This review discusses the incidence, reversibility, and impact of chemotherapy-induced alopecia and concludes that scalp cooling is the most effective prevention method in most cases, though some questions remain.

This review discusses the neurobiology and proposed mechanisms of scalp itch, but it does not report new clinical findings, highlighting the need for further research in this area.

This review discusses scalp skin disorders, their overlapping symptoms, diagnostic techniques, and treatment strategies, emphasizing the importance of accurate differential diagnosis, but reports no new clinical results.

Small white dots on the scalp seen with a dermoscope correspond to sweat ducts and vary with different hair disorders.

This study found that 4 weeks of finasteride treatment significantly decreased DHT levels in bald scalp to levels similar to hair-containing scalp in men with male pattern baldness.

This study successfully developed a reproducible mouse model demonstrating fetal scarless wound healing, which may provide insights for minimizing scarring in adults.

Hair follicles grow hair and release it through the skin.

This study found that certain C57BL/6 mouse substrains have a genetic vulnerability to skin lesions resembling central centrifugal cicatrical alopecia in humans, potentially worsened by high vitamin A levels.

This review discusses recent advances in scarless wound healing, focusing on strategies to create pro-regenerative scaffolds for repairing damaged skin, and reports no new clinical results.
