This study reports that citrulline, uniquely found in the inner root sheath of hair follicles, can be specifically detected with the carbamido diacetyl reaction, resulting in a bright orange color.

This study found that serial vertical sectioning of scalp biopsies significantly increases the histological diagnostic yield for alopecias.

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.

In this research, low-fluence light-based hair removal was explored, revealing its potential for at-home use with improvements in efficacy and safety, particularly for dark skin individuals, although further studies are necessary.

This study found that in vivo confocal scanning laser microscopy accurately quantifies neogenic hair follicles in mice, producing results similar to histology while avoiding fixation artifacts.

Hair diameter diversity is a key sign for diagnosing and managing male pattern baldness.

In this study, the authors found that rabbit hair material ground for 8 hours had better suitability and histocompatibility for injectable soft tissue augmentation compared to other tested formulations.

This study analyzed skin specimens from Australian Merino ewes to estimate hair follicle properties across different strains, providing baseline data essential for future genetic studies on fleece structure, but reported no new conclusions.

The review concludes that accurate diagnosis of different types of hair loss requires proper biopsy techniques and understanding the hair growth cycle and underlying causes.

In this study, researchers showed that multiphoton microscopy with fluorescent protein tagging enables single-cell imaging and tracking in live transgenic mice, offering new insights into cell dynamics in stem cell research compared to traditional histological methods.

This review discusses techniques and models for assessing hair growth activity but reports no new clinical findings, emphasizing the need for standardization and improved animal models.

Dermoscopy is a good, noninvasive way to see normal cat skin structures and could be useful for check-ups.

This study suggests that infrared thermography may be a useful noninvasive tool for diagnosing active phases of frontal fibrosing alopecia when combined with dermoscopy.

This study concluded that the Spa Touch system effectively retards hair regrowth, functioning like a "light razor" for quick and cost-effective epilation.

This study examined hair follicles from 14 Caucasian males and found that catagen-phase follicles were more prevalent (7.5%) than previously reported, challenging the established view that telogen-phase follicles are more common.

This article reviews various treatment options for diseases associated with cicatricial alopecia but reports no new clinical results.

This review discusses the significant progress in the diagnosis and treatment of hair loss disorders over the last 30 years and reports no new clinical results.

This study observed that a 3D culture model of hair follicle cells showed an anagen-like phase between days 3 to 6 and transitioned to a catagen-like phase by day 7, highlighting cell differentiation and structural development over time.

This case report highlights that diagnosing fungal skin infections in immunocompromised patients requires culture for accurate identification, as histologic findings alone can be misleading.

This review discusses histologic findings in alopecia and emphasizes the importance of understanding normal follicular anatomy and cycles in transverse sections, without reporting new results.

This review outlines the mechanisms, clinical features, and management strategies for alopecia areata and presents no new experimental findings.

This study reviewed and reclassified 37 cases of primary scarring alopecia using histological methods to achieve more accurate diagnoses within subtypes like lupus erythematosus and lichen planopilaris.

This article reviews major types of genetic hair shaft defects and associated syndromes, emphasizing understanding histologic features and diagnostic methods, but reports no new clinical findings.

In this study, the proposed MSF-VMDNet, combining dual encoder networks with a multi-frequency domain mechanism, significantly outperformed existing methods in segmenting skin cancer tissues from histological slide images, achieving high accuracy with an MIoU of 95.37% and a Dice coefficient of 95.11%.

This study developed a method to culture and maintain chicken feather follicles in vitro, preserving structure and biology similar to their in vivo state, though some gene expression was altered.

This study introduced a noninvasive spectroscopy method to assess hair follicle stages in mice by measuring skin diffuse reflectance and melanin dynamics, offering a potential tool for hair regeneration research.

This review discusses various non-invasive methods for diagnosing alopecia areata, highlighting that trichoscopy signs like short vellus hairs and yellow dots are sensitive indicators of the condition, while advanced imaging techniques provide valuable information on hair follicle status and scalp inflammation.

This article describes a rare case of alopecia with both scarring and non-scarring features, combining histologic signs of central centrifugal cicatricial alopecia with select immunologic features of alopecia areata.

In this study, trypsin digestion was found to be a faster and more efficient method than the explant technique for extracting bulge-derived keratinocytes from adult scalp biopsies.

This paper introduces the Follicular Unit Extraction procedure and its accompanying FOX Test, finding that 60% of tested patients were suitable candidates for this minimally invasive hair transplantation method.
