540-570 / 1000+ resultsresearch Early-age-dependent selective decrease of differentiation potential of hair-follicle-associated pluripotent (HAP) stem cells to beating cardiac-muscle cells
Younger mice's hair-follicle stem cells are better at turning into heart cells than older mice's.
research Effect of oil application, age, diet, and pigmentation on the tensile strength and breaking point of hair
Children's hair is more elastic, but tensile strength is similar across different factors.
research Influence of the cosmetic treatment of hair on drug testing
Cosmetic hair treatments like bleaching and dyeing reduce drug levels in hair samples.
research Postsclerotherapy Hyperpigmentation: A Histologic Evaluation
Most patients' skin darkening after sclerotherapy fades on its own within 6-24 months.
research Stability of opiates in hair fibers after exposure to cosmetic treatment
Cosmetic treatments like bleaching and perming can greatly reduce opiate levels in hair, possibly leading to false-negative drug tests.
research Investigation of human hair fibers using lateral force microscopy
Hair treatments like bleaching increase friction by exposing tiny pores on the hair surface.
research Distribution and Localization of Hydrophobic and Ionic Chemical Groups at the Surface of Bleached Human Hair Fibers
Bleaching hair removes its protective top layer and exposes more hydrophilic groups, changing its chemical surface and affecting how it interacts with products.
research Ultrastructural alterations and environmental exposure influence the opiate concentrations in hair of drug addicts
Environmental factors can greatly reduce drug levels in hair.
research Solar-Induced Postinflammatory Hyperpigmentation after Laser Hair Removal
Sun exposure after laser hair removal can cause skin darkening, which is hard to treat and requires avoiding UV light.
research Raman spectroscopy and electronic microscopy structural studies of Caucasian and Afro human hair
Hair treatments cause significant structural changes, especially with excessive heat, regardless of ethnicity.
research Investigation of the damage on the outermost hair surface using ToF‐SIMS and XPS
Bleaching hair causes significant damage by breaking down proteins and fatty acids.
research The proteomic profile of hair damage
Bleaching hair damages protein structure, especially keratin, leading to weakened hair.
research Influence of Oxidative and/or Reductive Treatment on Human Hair (I): Analysis of Hair-Damage after Oxidative and/or Reductive Treatment
Chemical treatments and daily stresses damage hair, especially the cuticle layer.
research Effect of Surface Treatments on the Nanomechanical Properties of Human Hair
Bleaching and combing damage hair's surface and mechanical properties.
research Chemical and physical treatments damage Caucasian and Afro‐ethnic hair fibre: analytical and image assays
Chemical and physical treatments like bleaching, dyeing, and UV radiation damage both Caucasian and Afro-ethnic hair.
research Pigmentation and Pregnancy
Most skin changes during pregnancy are harmless and moles don't significantly change, but many women experience pigmentation changes due to hormones and sun exposure.
research Hair removal
Current hair removal methods improve appearance but need more research for better options.
