This study reported that polarized dermoscopy was better for visualizing vascular patterns, scaling, and reticular pigmentation, while nonpolarized mode better documented features like black dots and tapered hair in various hair and scalp conditions.

In this study, researchers found that mogamulizumab-associated rashes and alopecia are common in patients treated for mycosis fungoides and Sézary syndrome and may be linked with a good treatment response.

This study found that trichoscopy, a non-invasive diagnostic method, may effectively differentiate between types of focal alopecia in the parietal area in adult women, indicating specific trichoscopic features for conditions like alopecia areata, discoid lupus erythematosus, and lichen planopilaris.

This study characterizes alopecia in ARCI, highlighting its prevalence among patients with severe forms and revealing new associated trichoscopic features.

This study found that hair follicle and interfollicular epidermis stem cells contribute differently to skin regeneration, with their persistence influenced by factors like spatial constraints and competition moderated by Notch suppression.

This review highlights the need for methodologies to understand and quantify drug penetration into hair follicles as significant drug pathways, noting this area lacks comprehensive articles and reports no new results.

The researchers reported that topical tofacitinib in mice increased hair follicles in the growth phase and boosted noggin and BMP4 mRNA expressions, compared to a vehicle and minoxidil.

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

This article discusses how the balding scalp's exposure to UV and near-infrared light may accelerate aging, with changes detectable under ultraviolet light; it presents no new clinical findings.

This study observed that among 120 patients recovering from COVID-19, severe diffuse hair loss typically began less than two months post-infection, with the majority of patients experiencing a severe degree of hair loss and positive hair pull tests, often alongside vitamin D deficiency.

New research suggests that skin cell renewal may not require a special type of cell previously thought to be essential.

This study found that COL17 deficiency in neonatal mice causes abnormal skin cell proliferation due to disrupted Wnt signaling, while replenishing or overexpressing COL17 can reverse this effect in both neonatal and aged skin.

This study found that deleting the miRNA processing enzymes Drosha and Dicer from mouse skin epithelial cells disrupted normal hair follicle development and maintenance, leading to follicular degradation and stem cell loss during the growth phase.

This case report describes alopecia universalis-like hair loss occurring in two patients with cutaneous T cell lymphoma, providing clinical, dermoscopic, and pathologic features to help differentiate it from alopecia areata universalis.

This study found that among patients with seborrheic dermatitis, the "dandelion" vascular conglomerate observed through trichoscopy was correlated with Malassezia scalp colonization.

In this study, researchers found that dermoscopy does not provide distinguishing features for diagnosing scalp contact dermatitis from topical minoxidil compared to other causes of severe scalp itching.

This review examines the use of dermoscopy for diagnosing common hair disorders and highlights its importance, but it does not report new clinical results.

This chapter reviews trichoscopic criteria and diagnostic features for various hair and scalp conditions, emphasizing their utility in non-invasive diagnosis, but reports no new clinical results.

Fibrosing alopecia in a pattern distribution is a unique hair loss condition with inflammation and scarring, resembling but distinct from common balding.

This study found a significant discordance between clinical symptoms and dermatoscopic signs with histopathological inflammation in patients with LPP and AFF, affecting diagnostic and therapeutic approaches.

This study observed that following hair transplantation, patients exhibited prominent perifollicular erythema and scaling one month after surgery, whereas by six months, accentuated follicular ostia and varying hair shaft abnormalities were consistently noted.

In this study, an infection model using rabbits was developed for dermatophytosis by inoculating macroconidia of Microsporum species, showing that direct intradermal application effectively progressed to the skin invasion phase and highlighted the correlation between severity of symptoms and duration post-inoculation.

This study reported that different types of alopecia have distinctive dermoscopic patterns, which aids in their diagnosis.

Trichoscopy helps diagnose and manage different types of hair loss effectively.

This study found that scarring alopecia is common in autosomal recessive congenital ichthyosis patients and significantly correlates with the disease's severity, highlighting the need for thorough hair evaluations in clinical management.

This pilot study found that examining changes in scalp scales after scraping may effectively distinguish seborrheic dermatitis associated with androgenetic alopecia from fibrosing alopecia in a pattern distribution.

In this study, researchers observed that trichoscopy could reliably identify features such as anisotrichosis and signs associated with inflammation and fibrosis in female pattern hair loss, which may aid in assessing disease severity and guiding treatment decisions.

This study found that Lgr5 and Lgr6 stem cells both activated wound-healing genes, but only Lgr5 stem cells changed their identity to contribute to new skin formation during wound repair.

In this study, researchers used transcriptomics and modeling to uncover previously unknown cell populations and marker genes in developing hair follicles, providing insights into early cell fate establishment and offering tools for further research on skin appendages.

This case study describes a Doberman Pinscher with a unique alopecic variant of chronic cutaneous lupus erythematosus that progressed to systemic lupus erythematosus, highlighting a rare autoimmune alopecia form in dogs.
