This study explored the role of Twist2 in fetal wound healing in embryonic mice, observing that its expression was vital for scarless regeneration and normal hair follicle formation; Twist2 knockdown led to visible scars and defective follicle formation.

In this study, researchers found that the protein Twist2 plays a crucial role in scarless wound healing in early embryonic mouse skins, with its knockdown leading to visible scarring and defective hair follicle formation, suggesting potential therapeutic targets for reducing scars and promoting regeneration.

In this study of 30 severe anorexia nervosa patients, true acquired pili torti was not found although twisted hair was observed in 6.6% of cases.

This study found that Twist1 and Tcf4 synergistically regulate the hair follicle induction ability of dermal papilla cells by forming a complex with β-catenin, enhancing their biological properties.

This study found that deleting the transcription factor Twist1 in keratinocytes significantly reduced UVB-induced skin carcinogenesis in mice, suggesting a potential target for preventing cutaneous squamous cell carcinoma.

Twisting hair weakens it, but strength can be recovered at low twist levels.

Scurvy, caused by vitamin C deficiency, can occur in people with restrictive diets and can be diagnosed by twisted hair shafts.

This study found that hair follicles with twisted bulbs demonstrated similar survival rates to intact follicles after transplantation into nude mice, suggesting they may be viable for use in FUE surgery.

This study found that deleting the Twist1 gene in skin keratinocytes significantly reduced UVB-induced skin cancer and hyperproliferation in mice and suggested Twist1 as a target for skin cancer prevention.

This review discusses the genetic basis of woolly hair syndrome and its potential link to heart disorders, highlighting recent discoveries of new molecular pathways and suggesting possible future treatment options.

Keratin fibers in hair twist left-handed.

This study found that TRPV1 activation in human scalp hair follicles inhibited hair shaft elongation, suppressed proliferation, and induced apoptosis, suggesting TRPV1 as a potential target for managing hair growth and epithelial disorders.

This study found that VR1 activation in human hair follicles inhibited hair growth by suppressing proliferation and promoting apoptosis, suggesting VR1 plays an important role in hair growth regulation.

This paper discusses the multipotency of cyst cells and proposes that understanding molecular circuits in cyst formation could enable engineering of desired stem cell culture phenotypes, but reports no new experimental outcomes.

This case study reported that a 40-year-old woman with Graves' disease developed severe thrombocytopenia after starting methimazole, suggesting a rare but serious risk of methimazole-induced immune thrombocytopenia and underscoring the need for close monitoring.

In this study, researchers found that the primary cause of slippage and detachment of keratin capsules in hair extensions is the re-contamination by oily residues from the hairdresser's hands, rather than the use of hair care products like masks or conditioners.

This study found that in wound-induced hair neogenesis, African spiny mice and laboratory mice exhibit different morphogenetic field formation patterns related to tissue stiffness, suggesting evolutionary developmental biology advantages.

This study found that in a mouse model of Gorlin syndrome, constitutive activation of signaling in dermal cells led to abnormal follicular growth, indicating non-epidermal factors may contribute to the disease.

This study found that trichoscopy can effectively differentiate scalp psoriasis from seborrheic dermatitis by identifying specific trichoscopic patterns such as hidden hairs, signet ring vessels, and comma vessels.

This study examined developing hair cortex with electron microscopy and found that keratin fibrils form between specific regions in hair follicles and aggregate into twisted cables.

Lack of small, fine hair on the front hairline is a key sign of frontal fibrosing alopecia.

This review proposes a classification system for childhood hair loss based on clinical appearance, age of onset, and associated symptoms, but reports no new clinical results.

This case report describes a 23-year-old man with scurvy, characterized by perifollicular hemorrhages, gum disease, and other symptoms due to a diet low in fresh fruits and vegetables.

This study found that adult patients with Myotonic Dystrophy type 1 exhibited a higher prevalence of various morphofunctional, inflammatory, and proliferative skin disorders compared to healthy controls.

Researchers found a new genetic mutation causing a rare hair loss condition in the first Japanese child studied.

In this observational study, dermoscopy was found to be a useful tool in diagnosing lichen planopilaris among patients with primary cicatricial alopecia.

This case report identified a 4-month-old boy with Menkes disease, a neurodegenerative disorder of copper metabolism, noting symptoms like recurrent seizures, developmental delay, and specific physical characteristics, confirmed by genetic sequencing showing a pathogenic ATP7A mutation and low serum copper and ceruloplasmin levels.

This case report describes the trichoscopic and histological features observed in a 7-year-old boy with morphea en coup de sabre and details the positive response to systemic immunosuppressive therapy.

In this study, researchers used spatial transcriptomics to identify increased expression of genes linked to extracellular matrix organization and epithelial–mesenchymal transition in the progenitor cell regions of hair follicles in androgenetic alopecia patients, suggesting a possible role in progenitor cell loss and fibrogenic microenvironment development.

This study found that skin bacteria promote regeneration in wound-induced hair follicle neogenesis, suggesting a role for IL-1β signaling and challenging the belief that infection inhibits healing.
