Loose anagen hair syndrome in children may improve with age, but treatment results vary.

The researchers reported that DHT-inducible DKK-1 may play a significant role in DHT-driven balding by inhibiting hair follicle cell growth and promoting apoptosis in androgenetic alopecia.

This study found that root hair length and density in rice are controlled by distinct genomic regions, with 18 regions identified but no overlap between the traits.

In this study, researchers identified a novel KRT74 gene mutation associated with autosomal recessive pure hair and nail ectodermal dysplasia in a Pakistani family, expanding the known genetic causes of the disorder.

This study suggests that the expression patterns of keratin and filaggrin indicate milia may originate from the outermost cells of the hair bulge in the outer root sheath.

In laboratory and artificial skin model experiments, this study found that plant-derived PDRN from Korean ginseng effectively promoted skin cell regeneration and strengthened the skin barrier, suggesting a sustainable alternative to animal-derived PDRN.

This report provides the first microscopic description of pachyonychia congenita-associated alopecia, identifying a combination of histological features that might be unique to this condition.

This study found that hair root sheaths can be accurately typed for erythrocyte acid phosphatase, adenylate kinase, and adenosine deaminase, consistent with blood typing results from the same donors.

This case report describes a 24-year-old female with systemic lupus erythematosus and aggressive periodontitis, showing satisfactory outcomes after treatment with nonsurgical periodontal therapy and xenograft over an 8-year follow-up.

This study found that PRX102, a peroxidase with a unique polar localization pattern, plays a role in root hair growth by aiding the transport of materials to the tips of growing root hairs.

In this case study, an 8-year-old boy with alopecia totalis experienced significant hair regrowth after baricitinib treatment, suggesting KRT74 variants may influence immune dysregulation in this condition.

This study examined the formation of acquired curved hair and found that the fusion of hair matrix cells during follicle regeneration contributes to asymmetric follicle shapes and curved hair, potentially linked to changes in type IV collagen and protein expression levels.

This study found that the Pseudomonas sp. T5-6-I strain significantly increased selenium accumulation and root hair density in Brassica oleracea, highlighting its potential for phytoremediation and biofortification.

In this study, the gene SlPHL1 was identified as a transcription factor in tomatoes that enhances phosphate starvation responses by upregulating specific genes.

This study used single-cell RNA sequencing to map the cellular composition of sheep hair follicles, revealing differentiation pathways and potential molecular mechanisms for wool curvature, which may inform sheep breeding.

This review discusses methods for evaluating hair growth-promoting effects of candidate substances for androgenetic alopecia, focusing on cell assays, organ cultures, and animal models, and reports no new results.

This study found that hair loss in an Olmsted syndrome mouse model with a Trpv3 mutation was linked to premature keratinocyte maturation, affecting hair follicle structure and function.

In this study, low-dose 453 nm blue light appeared to enhance hair growth by interacting with specific photoreceptors in the outer root sheath cells.

This study found that the vitamin D receptor is crucial for initiating the postnatal hair follicular cycle in mice, preventing alopecia associated with its inactivation.

This case report highlights the importance of considering hair-thread tourniquet syndrome as a potential diagnosis for girls with genital swelling and pain, emphasizing the need for prompt intervention.

This study suggests that immunohistochemistry of keratin and involucrin expression can aid in distinguishing malignant trichilemmoma from other tumors previously diagnosed as such.

A missing mK6irs1 gene causes hair loss in mice.

Apoptosis in hair follicles varies by growth phase, with TGF-β possibly starting the catagen phase.

This study reported that low-dose oral minoxidil is generally safe for treating various types of hair loss, though it may cause hypertrichosis and pedal edema, especially at higher doses.

In this study, analysis of hair root status showed similar abnormalities in both primary and secondary syphilis patients, though it remains unclear if these are specific to syphilis.

This study found that chemotherapy in female breast cancer patients caused significant early hair loss, which began to recover three months after completion, whereas tamoxifen did not affect hair growth.

This study reports that structural abnormalities in the inner root sheath of hair follicles may cause the hair shaft to be loosely attached in patients with loose anagen hair syndrome.

In this survey-based study, researchers reported a high prevalence of hair loss among subjects in Delhi and the National Capital Region and noted widespread unawareness of its dietary, hormonal, genetic, and environmental causes.

This study observed two cases of pigmented epithelioid melanocytoma suggesting potential differing origins: one from a hair follicle's outer root sheath and another from an intradermal nevus.

This case report identifies a novel LIPH gene mutation linked to autosomal recessive woolly hair/hypotrichosis in a Japanese boy, expanding the spectrum of known mutations associated with this condition.
