This case report describes a 3-year-old male with X-linked ichthyosis and associated neurologic abnormalities, identifying an unusual cortical development malformation and suggesting that abnormal hair banding may assist diagnosis.

In this study, a square pulse, low-fluence IPL device used at home significantly reduced terminal hair count by 87% six months post-treatment, with evidence of hair miniaturization similar to professional laser treatments.

In a comparative genomic study, researchers observed significant genetic differences among the three chemical races of the alga Botryococcus braunii, leading them to propose reclassifying these races as distinct species based on their unique genomic characteristics.

This study found that using henna dye positively affected hair cuticula pattern and diameters compared to undyed hair, though the degree of change may vary based on hair phenotype and condition prior to treatment.

This study found that hair dyes significantly affect DNA sequence analysis, with the organic extraction method performing better on hair shafts and the prepFiler kit yielding higher success for follicle-included samples.

This review highlights how forensic drug analysis in hair using modern instrumental techniques offers advantages such as easy sample collection and chronological tracking of drug use, emphasizing its value for law enforcement and other applications.

This study found that examining the microscopic and ultramicroscopic structures of donkey and horse hair can help differentiate between the species based on distinct differences in hair cuticle and brain substance patterns.

This study utilized advanced imaging techniques to quantify hair damage and dye uptake dynamics, revealing that compound penetration in hair is influenced by molecule size and lipophilicity.

This study observed a 31% decrease in antidepressant use among patients who were preoperatively taking such medication, suggesting cosmetic surgery may influence antidepressant needs.

This study observed that combining high-potency steroids with pimecrolimus might effectively stabilize hairline recession in frontal fibrosing alopecia patients.

This study found that combining optical clearing methods with light-sheet fluorescence microscopy allows detailed 3D visualization of normal and pathological human skin biopsies, revealing differences in epidermal thickness and volume.

This article describes standard methods for studying DNA methylation dynamics in mouse skin and hair follicle stem cells but presents no new research findings.

This study found that scanning electron microscopy revealed significant hair shaft changes in women using straighteners, but not in those using hair dye, suggesting its utility in assessing chemical treatment effects on hair.

This study found that nestin-expressing hair follicle-derived cells express higher levels of certain neurotrophic factors and neural markers, indicating potential for neuroregenerative therapy applications.

This study found that extracellular vesicles derived from mesenchymal stem cells and umbilical cord blood plasma enhanced wound healing and reduced scar formation in mice, suggesting their potential as therapeutic agents for skin repair.

This review discusses micro-segmental hair analysis for forensic toxicology, emphasizing its potential to provide detailed drug distribution profiles and its application in investigations, while noting the method's limitations and future perspectives.

This study concluded that TrichoScan is error-prone in its current form and overestimates certain hair growth parameters, with results not aligning with clinical severity of alopecia.

This study hypothesizes that a mummified 19th Century girl in San Francisco died of severe undernourishment potentially due to a bacterial-borne disease, highlighting historical health challenges mitigated by modern sanitation and medicine.

In this study, researchers found that non-invasive analysis of skin surface lipid RNAs revealed alterations in gene expression patterns associated with atopic dermatitis, suggesting its potential for understanding skin disease pathophysiology.

This study revealed that chronic restraint stress in mice led to significant alterations in metabolic pathways and gene expression associated with hair growth inhibition, using metabolomics and transcriptomics analyses.

In this study, the researchers found that a manual micrometer caliper is a reliable tool for planning hair transplant surgery and accurately measures the short axis of the hair shaft.

This study found that overexpressing the gene Thymosin β4 (Tβ4) can promote the growth and development of secondary hair follicle dermal papilla cells in cashmere goats, suggesting its potential as a target for increasing cashmere production.

In this case report, narrowband-UVB phototherapy successfully treated a rare instance of Graham Little-Piccardi-Lassueur syndrome, a variant of lichen planopilaris, as investigated through non-invasive imaging techniques.

This study suggests that RCM may be a promising non-invasive diagnostic tool for alopecia areata incognita, showing substantial agreement with histopathology while noting some discrepancies.

This historical review examines the diagnostic and etiological understanding of alopecia areata, emphasizing the evolution of theories and the impact of immunological data, while providing no new clinical results.

In this study of four Chinese goat breeds, black goats exhibited significantly higher melanin content, while Inner Mongolian cashmere goats had longer fiber lengths. These findings highlight genetic variations in coat color and fiber length, informing future breeding programs.

This systematic review and meta-analysis found that platelet-rich plasma (PRP) therapy is effective in increasing hair density and reducing hair loss for alopecia, with variations in response based on activation status.

In this study, black wolfberry ferment was found to promote hair regrowth in mice with androgenetic alopecia by increasing hair weight, follicle count, and skin thickness, potentially through PI3K/AKT, NF-kappa B, and MAPK signaling pathways.

This article reviews a tabletop microscopy method for recording electromagnetic radiation from tissues, using hair follicles as a model, and presents no new clinical findings.
