This article reviews the use of dermoscopy as a noninvasive tool for diagnosing various types of nonscarring alopecia but presents no new clinical findings.

In this case report, an elderly woman was diagnosed with tinea capitis and eyebrow involvement, which was initially misdiagnosed as alopecia areata, illustrating the importance of trichoscopy in correctly identifying this infection even in uncommon sites like the eyebrow.

This study aimed to identify trichoscopic features that help differentiate between tinea capitis and alopecia areata in children, enhancing diagnosis and treatment decisions visually and non-invasively.

This study found that dermal papilla-like tissues derived from canine adipose stem cells promoted new hair follicle formation and increased vascularization in athymic nude mice.

This study observed that alopecia areata can be induced and serially transferred in C3H/HeJ mice using skin grafts, providing a useful model for studying the disease in humans.

This study reported that exposure to 1,763 MHz radiofrequency radiation stimulated hair growth in vitro by inducing insulin-like growth factor-1 expression in cultured human dermal papilla cells.

This study concluded that hair-derived stem cells from older donors may offer a promising alternative for autologous corneal endothelial replacement, potentially benefitting patients of various age groups.

This study found that mechanical skin stretching can stimulate hair stem cell proliferation and hair regeneration by activating a complex pathway involving WNT, BMP-2, and M2 macrophages.

This study found that CRISPR/Cas9 efficiently edited two cellulose synthase-like genes in spinach, significantly altering root hair growth patterns and suggesting potential for large-scale genome editing in this crop.

This study reports that despite rescuing neurulation and skin barrier defects, Grhl3 gene overexpression in mice leads to hearing impairment, hair loss, and other developmental abnormalities, highlighting low tolerance for Grhl3 dysregulation.

In this study, researchers identified a gene regulatory network in Arabidopsis that controls root hair growth under low-temperature conditions, revealing specific transcription factors and downstream targets that contribute to this growth response despite overall plant development being halted.

This study observed that specific trichoscopic features like white peripilar signs, scalp pigmentation, and focal atrichia are associated with advanced female pattern hair loss in Fitzpatrick skin type III patients.

This study used integrated single-cell chromatin and transcriptomic analyses in developing mouse skin to uncover gene networks involved in skin lineage specification and identified Mef2c+ upper fibroblasts as potential precursors to certain muscle-like structures, with cross-species findings in human skin.

In this study, researchers showed that the CAP1 gene regulates root hair growth in plants by modulating cytoplasmic ammonium levels and maintaining calcium gradients, highlighting its role in ammonium homeostasis.

This study found that zebrafish and stickleback fish use similar genetic programs for tooth regeneration, despite differences in their dental structures.

This study developed immortalized human hair follicle-derived mesenchymal-like stromal cells (iHF-MSCs) as a consistent source of therapeutic secretome, reporting their superior immunomodulatory and regenerative performance, potentially advancing cell-free therapies for inflammation and tissue repair.

This review explores the mechanisms of hair cell death due to factors like noise, ototoxic drugs, and aging and reports no conclusive clinical results; ongoing research may eventually enable preventive treatments for hearing loss.

This study highlights a chronic case of hair fall in a female patient managed with constitutional homeopathy, lifestyle changes, and nutritional supplements, suggesting that individualized and integrative approaches can effectively improve conditions like hair loss.

This study demonstrated that disrupting EGFR signaling in mice leads to immune sensitivity compromising the hair follicle's protective environment, but JAK1/2 inhibition can restore this immune privilege and stimulate hair growth, suggesting a potential therapy for scarring hair loss diseases like cicatricial alopecia.

In this study, researchers observed that genetically identical cloned dogs, when exposed to different environments like an airport and a police station for two years, exhibited significant differences in toxic mineral concentrations and intestinal microbiota composition, suggesting that environment influences physiological traits even among clones.

In this study, the alcoholic extract DN106212 from Centipeda minima was shown to be more effective in promoting hair growth in C57BL/6 mice compared to dimethyl sulfoxide and tofacitinib, suggesting its potential as a natural hair growth agent.

This study found that a marine-extract dietary supplement significantly reduced hair shedding and increased hair diameter in premenopausal women with subclinical hair thinning or hair loss after 6 months of use.

This study found that the AtSfh1 protein in Arabidopsis is essential for phosphatidylinositol-4,5-bisphosphate signaling crucial to polarized root hair growth, utilizing both phosphatidylinositol and phosphatidylcholine-binding activities.

This study found that toll-like receptor 9 plays a previously unrecognized role in sensing skin injury and influencing tissue repair and regeneration in adult mice by modulating γδT cell migration.

In this study on mice, elevated IGF-1 levels in the skin were linked to premature aging of hair follicles, but interventions like reducing IGF-1 or using senolytic treatments helped restore stem cell health and counteract aging effects.

This review discusses the potential of adipose-derived tissue components like nanofat and stem cells for aesthetic rejuvenation, covering their use in hair growth, scar reduction, and more, without reporting new clinical results.

In this report, two adult cases of tinea capitis with unusual symptoms like pustules and non-scarring alopecia were diagnosed based on clinical and pathological findings, and successfully treated with oral Griseofulvin and topical luliconazole cream.

This review discusses the shared molecular and cellular processes in the early development stages of skin appendages like hair follicles, teeth, and mammary glands, reporting no new results.

This article discusses the uses and techniques of trichoscopy for hair and scalp disorders and reports no new clinical results.

This study used single-cell RNA sequencing to create a detailed atlas of human scalp hair follicles and found that early-stage hair graying involves matrix hair progenitor depletion linked to P53 pathway activation.
