In this study, researchers used single-cell RNA sequencing to map the hair follicle microenvironment in fine-wool sheep, identifying specific cell types and gene expressions that influence wool fiber diameter, with dermal papilla cells playing a significant role in hair follicle development.

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 describes the pelage cycle, hair types, and molt patterns in black-tailed deer, highlighting significant differences in hair properties among various developmental stages and populations.

In this study, researchers identified the crucial role of collet hairs in seedling survival by demonstrating that the collet hair-defective shv3 mutant lacked sufficient anchorage, compromising radicle penetration into the soil.

In this review, the authors summarize recent findings on dermal white adipose tissue (dWAT), highlighting its crucial role in the hair follicle microenvironment by regulating inflammation and immune responses, thus influencing hair regeneration.

This letter reports acquired progressive kinking of hair as a condition observed following COVID-19, but it presents no new scientific findings.

In this study, a new hairless gene in the Donryu rat strain was identified, showing skin similarities to human skin tumors with multiple follicular cysts.

This review discusses drugs as a common cause of diffuse, nonscarring hair loss, highlighting the importance of recognizing and discontinuing the offending medication to address drug-induced alopecia, and reports no new clinical results.

Recognizing bamboo hair helps diagnose Netherton’s syndrome.

This study found that loliolide enhanced hair growth-related functions in 3D dermal papilla spheroids by activating AKT/β-catenin signaling pathways, with increased expression of related growth factors and genes.

This study found that activating hair follicle resident T cells in a human organ culture can induce an alopecia areata-like immune response, and that the drug farudodstat partially reduced this effect.

This study found hair regrowth in the majority of AA-affected mice and rats treated with diphencyprone, suggesting its potential utility for understanding human alopecia areata and the drug's therapeutic action.

A specific gene mutation causes woolly hair and hair loss.

DNCB is highly effective for treating alopecia areata with minimal long-term side effects.

This study investigated the effects of biotin deficiency and adequacy on cell proliferation and DNA synthesis in isolated mohair follicles, particularly focusing on the incorporation of [methyl-3 H]thymidine.

This study observed that follicular dysplasia in Weimar Pointers produces histopathological features and hair abnormalities similar to color dilution alopecia, though less severe.

This study found that Undariopsis peterseniana extract may promote hair growth by activating specific cellular pathways, suggesting potential for treating alopecia.

In this study, researchers observed that Vdr-knockout mice experience hair cycle arrest during the catagen stage, leading to alopecia, with persistent epithelial strands forming in the hair follicles, indicating Vitamin D receptor's role in regulating hair follicle regression and regeneration.

The document concludes that a unique target-like hair regrowth pattern in alopecia areata may be more common than thought and should be properly identified.

This study found that dermoscopy showed distinctive patterns for different types of alopecia, supporting its clinical usefulness for diagnosing diseases with small round or oval hairless patches on the scalp.

This abstract does not provide specific findings or results.

This study examined the role of biotin deficiency and adequacy on cell proliferation and DNA synthesis in isolated mohair follicles.

This study identified histologic lesions and a defect in adhesion molecules causing hair loss in mice with the bal mutation, linked to a mutation in the desmoglein 3 gene.

This study suggests that macrophages, especially CD206+ subsets, play a key role in hair growth induced by squaric acid dibutyl ester, a therapy used for alopecia areata.

This study used cashmere goats to map the differentiation of dermal papilla stem cells and identified key intermediate cell states involved in hair follicle regeneration.

This article reviews various congenital and acquired hair shaft disorders, examining their characteristics and potential links to wider health conditions, but does not present any new clinical results.

This study identified a new mouse mutation associated with noninflammatory proliferative skin disease and hair abnormalities, drawing parallels to human conditions like Netherton's syndrome and monilethrix.

This study found that DNA-damaged hair follicle stem cells in mouse models do not show typical senescent markers but are dynamically expelled to maintain tissue health and prevent hair loss.

This study suggests that D2O increases hair length in nude mice by extending the hair cycle duration, particularly the hair-existing phase, which is associated with increased mast cell density.
