Oxidation changes the structure of hair protein filaments, causing them to compact and rearrange.
research Serum C-19 steroid sulphates in females with clinical hyperandrogenism
Women with hyperandrogenism have higher androgen levels and lower SHBG, which may contribute to conditions like excessive hair growth and early puberty.
research Mutations in Homocysteine Metabolism Genes Increase Keratin N-Homocysteinylation and Damage in Mice
Genetic mutations that disrupt homocysteine breakdown lead to increased damage in mouse hair keratin.
research Sulfatase inhibitors: a patent review
The document concludes that research on sulfatase inhibitors should continue due to their potential in treating various diseases, despite some clinical trial failures.
research Silicones as conditioning agents in shampoos

Thiadiazole chitosan conjugates improve hair manageability, moisture, and protection in conditioners.
research Disulfide Cross-Linked Network Structure of Intermediate Filament and Matrix in Hair and Wool Cortices
Hair and wool strength is affected by the number and type of bonds in their protein structures, with hair having more protein aggregates than wool.
research The Viscoelastic Properties of Chemically Modified alpha-Keratins in Human Hair
Chemical modifications can alter hair's stability and flexibility, with hydrophobic interactions helping maintain structure in humid conditions.
research Dietary Aspects for Selenium and/or Selenium Compounds
Getting the right amount of selenium is important for health; too little can cause disease, and too much can lead to toxicity.
research A New Case of Isolated Trichothiodystrophy
A rare case of isolated trichothiodystrophy was identified, marked by brittle hair with low sulfur content.
research Roles of steroid sulfatase in brain and other tissues
Steroid sulfatase is important for activating hormones that affect memory, brain function, and certain diseases, and could be a target for treating hormone-related disorders.
research Abstracts: Reduction‐induced surface modification of human hair
Chemical treatments change hair surface properties, making it more hydrophilic and able to bind conditioners.
research Ultrastructural visualization of cross-linked protein features in epidermal appendages
Cross-linked proteins help maintain the structure of hair, feathers, and hagfish teeth.
research Trichothiodystrophy hair shafts display distinct ultrastructural features
Trichothiodystrophy hair is structurally abnormal with protein and organization issues.
