Seborrheic dermatitis affects quality of life and sleep, linked to stress and nervous system changes.

This study identified a mutation in the CST6 gene linked to a rare syndrome with symptoms affecting hair and skin, revealing cystatin M/E's role in maintaining epidermal homeostasis and hair follicle development.

The researchers reported that using exosomes from hair follicle stem cells with acellular nerve allografts helped bridge facial nerve defects in rats and may match the effectiveness of autograft therapy.

This study assessed patient satisfaction and hair retention in 15 individuals with alopecia treated with Biofibre ® 4.0 artificial hair implants, finding high levels of satisfaction and excellent biocompatibility, with no significant adverse reactions reported after one year.

In this study, increasing the methionine level in the diet of pregnant female rabbits stimulated the development of hair follicles in their offspring and improved hair fiber diameter.

This study found that increasing methionine in the diet of pregnant rabbits may stimulate the development of hair follicles and improve hair fiber diameter in their offspring.

In this pilot study, participants with lymphocytic primary cicatricial alopecia who applied 6% topical gabapentin solution twice daily for 12 weeks experienced significant symptom reduction, though there was no noticeable change in nerve fibre density or neuropeptide expression.

This study found that transplanting hair follicles into human scars may remodel fibrotic tissue and reduce scarring by altering collagen structure and decreasing pro-fibrotic factors.

Researchers observed that dutasteride and finasteride caused structural changes in the penises of both control and hypertensive rats, with dutasteride having a more pronounced effect on the corpus cavernosum.

This study found that Cream 1 effectively prevented UV radiation-induced nerve ending damage in human skin samples, unlike placebo and SPF15 creams.

This study found that applying topical 6% gabapentin twice daily reduced disease activity and scalp pruritus in a patient with lymphocytic cicatricial alopecia, with no adverse effects reported.

This study found that Sonic Hedgehog protein treatment enhanced the sprouting and regeneration of pelvic ganglia and cavernous nerves after injury, with localization of delivery affecting outcomes.

This study observed that both dutasteride and finasteride affected penile morphology in normotensive and hypertensive rats, with more pronounced changes in hypertensive animals, especially when treated with dutasteride.

This study found that Hetian sheep with higher wool density produce more and finer wool, with key genes potentially influencing their wool growth and density.

This study found that long noncoding RNA profiles in Wan strain Angora rabbits may help understand the molecular mechanisms regulating hair follicle density, potentially influencing wool fiber production.

This study found that systemic ovalbumin–aluminum sensitization followed by cutaneous challenge in mice induced thermal hyperalgesia, increased spinal cord gliosis, and sprouting of nociceptive fibers, along with elevated mast cell and nerve profile densities in the skin compared to controls.

This study observed an association between intense itching in anterior chest keloids and an increased density of nerve fibers in the epidermis, alongside elevated expression of the pruritus mediator substance P, though no difference was found in Langerhans cells related to pruritus, location, or region.

This study found that the occipital scalp had significantly higher epidermal nerve fiber density than the frontoparietal scalp, which may explain increased sensitivity in some patients.

This study found that topical mesenchymal stem cell conditioned medium improved skin structure by increasing collagen fiber density, hair follicles, and blood vessel number in a mouse model of skin aging.

This study found that elastic fibre arrangements in the skin of domesticated mammals vary with hair density, with densely-haired species having horizontal fibres and sparsely-haired ones exhibiting a sponge-like system.

In this study, researchers identified two genetic mutations associated with producing finer and denser wool in fine-wool sheep, involving the genes KRT74 and EDAR, which may guide future breeding efforts to enhance wool quality.

This article discusses patient-driven innovations in hair restoration surgery, including the rise and fall of synthetic fiber implantation, but reports no new clinical findings.

This study observed that mesenchymal stem cell-conditioned medium accelerated burn wound healing in rats by enhancing epidermal growth factor presence, improving wound closure, collagen density, and re-epithelialization compared to the control.

This study found that human hair fibers significantly improve the shear behavior of dry sand, but under saturated conditions, the reinforcement sustains shear strength similar to unreinforced sand.

In this experimental study, hyaluronic acid injections in BALB/c mice improved wound healing by increasing fibroblast numbers, collagen density, and epithelium thickness, while also enhancing hair growth, suggesting potential benefits for scar prevention in sutured incisions.

This case report highlights the importance of considering artefacts like artificial hair fibers during trichoscopy, as they can interfere with the accurate diagnosis of hair conditions.

In this study, subcutaneous injection of mesenchymal stem cell-conditioned medium promoted regeneration of mice skin aged by D-galactose, improving skin thickness, vascularization, and collagen density.

This study used molecular dynamics simulations to illustrate the complex molecular behavior of the hair surface F-layer, highlighting how fatty acids interact with 18-MEA under different conditions.

This study reports that biomass activated carbon fibers derived from metaplexis japonica seed hair effectively adsorb methylene blue dye, demonstrating high capacity and rapid adsorption performance.

New resin B makes artificial hair fibers hold curls longer than traditional resin A.
