This study introduced a Density-Calibrated Airtouch Protocol (DCAP) that suggests customizing the Airtouch hair coloring technique based on client hair density to optimize color blend, pigment longevity, and hair health.

This study reports an unusual finding of plucked anagen hairs with intact hair papilla and connective tissue sheath in various scalp disorders, suggesting further documentation is needed.

This article introduces a novel, inexpensive hair preparation technique using glove-finger sheaths to secure and protect hair during calvarial surgery, reducing procedure time and hair damage without the need for full scalp shaving.

This letter discusses the use of serial trichoscopy versus a modified hair pull test for monitoring localized alopecia areata but reports no new clinical results.

This research found that modifying brachytherapy seeds with contrast-enhancing materials in photoacoustic imaging increased signal-to-noise ratios and imaging depth, and demonstrated potential for tissue differentiation by analyzing temperature-induced changes in PA intensity.

This study on feather pattern formation in chicken skin found that inhibiting gap junctional intercellular communication can lead to the emergence of new feather buds in specific spatial patterns, suggesting that GJIC may facilitate Turing-type periodic patterning by propagating inhibitory signals over long distances.

This study explains surgical techniques for hair transplantation using the sharp implanter method, emphasizing 11 key principles that optimize efficiency and precision, and reports high graft survival and natural hair density when these principles are followed.

Frequent hairdryer use may worsen hair fragility in people with Pili Annulati.

This article presents a protocol for using mouse tail skin to study hair follicle stem cells, enabling visualization of calcium signaling and other cellular features in various conditions but reports no new research data.

In this study using ex vivo porcine ear skin, researchers found that standard nail varnish applied gently creates effective follicular closures, preventing penetration of certain substances like fluorescein sodium salt and caffeine into hair follicles, whereas solvent-free varnish and rapid application techniques were less effective.

This study identified several specific trichoscopic features of trichotillomania, with trichoptilosis, V hair, and hair powder being the most frequent findings.

This review discusses follicular unit transplantation for hair restoration, focusing on crucial aspects such as donor assessment and surgical technique, but reports no clinical results; the authors stress the importance of careful planning and skilled execution.

This case study reports that combining surgery and photodynamic therapy effectively treated a 19-year-old male with perifolliculitis capitis abscedens et suffodiens, proving especially beneficial for patients unresponsive to traditional treatments.

This study found that scanning electron microscopy can identify four specific hair morphology patterns in alopecia areata patients, offering a less invasive diagnostic option compared to punch biopsy.

The study reported that combining the Follicular Closing Technique with the Franz diffusion cell is a valuable method for investigating follicular caffeine penetration in vitro, though kinetics differ from in vivo results.

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.

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 mesenchymal cell processes from the dermal papilla contact epithelial hair matrix cells through gaps in the basal lamina during hair matrix cell differentiation in mouse vibrissa follicles.

In this article, researchers describe a novel FUE device designed to enhance follicular unit excision surgery by minimizing follicular injury and improving ergonomics with features such as Bluetooth functionality, fingertip touch sensors, and automated operation.

This study found that, among 100 patients with alopecia areata, the most prevalent subtype was patchy alopecia areata, with characteristic trichoscopic features including black dots, yellow dots, and empty hair follicles.

This study found that RCM combined with dermoscopy can differentiate disease states between alopecia areata, tinea capitis, nevus sebaceous, and linear scleroderma of the scalp by identifying distinct dermal and follicular patterns.

This study found that methylene blue staining helped identify late catagen and telogen hair follicles more accurately than unstained follicles, which suggests that established telogen percentage standards may be overestimated.

This study used single-cell and spatial transcriptomic profiling to identify specific molecular markers in human follicular dermal papilla cells, enhancing understanding of their role in hair follicle development.

This review discusses the application of trichoscopy in diagnosing various hair and scalp diseases and reports no new clinical results; the authors emphasize its role as a non-invasive diagnostic tool.

A man unhappy with his old hair restoration got a new, natural-looking hairline using a combination of follicular unit extraction and punch graft reduction.

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

In this study, researchers developed a three-dimensional ultrastructural analysis tool using serial block-face scanning electron microscopy to reveal detailed nerve networks and muscle structures in human skin tissues, demonstrating the technique's potential to study structural changes in aging or disease.

This case study found that multiparametric ultrasound can be an effective non-invasive diagnostic tool for evaluating scalp changes in alopecia areata following repeated corticosteroid injections, potentially offering an alternative to biopsy.
