Permanent hair waving uses chemicals to create long-lasting curls.
research Reimagining Hair Science: A New Approach to Classify Curly Hair Phenotypes via New Quantitative Geometric and Structural Mechanical Parameters
New methods can better classify curly hair types and lead to improved hair care products.
research Characterization of curved hair of Japanese women with reference to internal structures and amino acid composition.
Japanese women's curved hair has an uneven internal structure and varying amino acid composition.
research Improved two‐dimensional electrophoretic mapping of Japanese human hair proteins; application to curved and straight Japanese human hairs; and protein identification by MALDI MS and MS/MS quadrupole time‐of‐flight mass spectrometry
The study found that minor protein differences between curved and straight Japanese hair are unlikely to significantly affect hair structure.
research Perceptions of female age, health and attractiveness vary with systematic hair manipulations
Shiny, straight hair is seen as more youthful, healthy, and attractive.
research Thermal Analysis of the Straight Permed Hair
Straight permed hair loses weight faster than virgin hair when heated, but ends up heavier after burning.
research Health improvement of human hair and their reshaping using recombinant keratin K31
Recombinant keratin K31 makes damaged hair thicker, stronger, and straighter.
research The effect of treatments on the shear modulus of human hair measured by the single fiber torsion pendulum.
Different treatments change the strength and flexibility of human hair.
research DSC-investigations of alpha-keratins and the specific effects of chemical treatments on human hair
Chemical treatments weaken hair's thermal stability and structure.
research Hair curvature: a natural dialectic and review
The document concludes that hair curvature can be explained by the growth patterns caused by the shape and separation of cells in the hair follicle and is affected by specific molecular pathways.
research Internal structure changes in bleached black human hair resulting from chemical treatments: A Raman spectroscopic investigation
Chemical treatments on bleached black hair change its internal structure by breaking and reforming bonds, and treatments with hydrolyzed eggwhite protein help repair it.
research Characteristic Microstructure of Curved Human Hair
Curved human hair has different structures on each side, which might cause its shape and is similar to wool.
research Unilateral Straight Hair—A Symptom of Acquired Horner's Syndrome in a Neonate
A baby girl's hair turned straight on one side due to a neck tumor and surgery, but it returned to curly as she recovered.

New eco-friendly method strengthens and sets hair using light and causes less damage.
research Application of single hair fibre tensile measurements to create an industry‐standard heat damage scale for hair
A new 6-point scale reliably measures heat damage to hair from styling tools.
research Human hair form. Morphology revealed by light and scanning electron microscopy and computer aided three-dimensional reconstruction.
Hair follicle shape determines hair type: curly, straight, or in-between.
research Effect of Surface Treatments on the Nanomechanical Properties of Human Hair
Bleaching and combing damage hair's surface and mechanical properties.
research Cortical cell types and intermediate filament arrangements correlate with fiber curvature in Japanese human hair
Hair curvature in Japanese people is linked to specific cell types and filament arrangements in the hair cortex.
research Hair Styling: Technology and Formulations
Hair styling products and tools help improve hair's look and manageability but can damage hair if used incorrectly.
