The technique showed that human hair has two main parts, with 68% being rigid and the rest flexible, and water swelling affects its structure.

Changing disulfide bonds in human hair affects its melting behavior and thermal stability.

Hair structure changes immediately during perm treatment, with initial damage partially restored later.

Human hair can almost fully recover its structure within about 1,000 minutes after being stretched.

Human hair keratins can self-assemble and support cell growth, useful for biomedical applications.

Disulfide bonds affect the melting behavior of hair's crystalline structure, but hair retains some stability even after these bonds are broken.

Curved human hair has different structures on each side, which might cause its shape and is similar to wool.

Curly and straight hair differ in how their internal fibers are arranged.

Trichohyalin makes hair follicles stronger.

Keratin proteins in epithelial cells are dynamic and crucial for cell processes and disease understanding.

Researchers found that the most reachable bonds in wool fibers are near the ends of certain proteins, which help stabilize the fiber's structure.

Hair keratin-associated proteins are essential for strong hair, with over 80 genes showing specific patterns and variations among people.

Keratin mutations cause skin diseases and could lead to new treatments.

Mutations in keratin genes cause cell fragility and various skin disorders.

Hair growth is controlled by specific gene clusters and proteins, and cysteine affects hair gene expression in sheep.

Different hair protein amounts change the strength of keratin/chitosan gels, useful for making predictable tissue engineering materials.

Human hair proteins can help blood clot when mixed in equal parts.

Scientists made nanoparticles from human hair proteins to improve drug delivery.

Oxidized hair can naturally regain strength and stability over six months.

Thioglycolic acid and L-cysteine change hair structure differently during perms, affecting hair strength and curling efficiency.

Hormones control keratin production in skin and hair.

Keratins are important for skin cell health and their problems can cause diseases.

Human hair has different protein structures in its cuticle and cortex.

Hair's internal fibers are arranged in a pattern that doesn't let much water in, and treatments like oils and heat change how much water hair can absorb.

Keratin structure in hair is stable at pH 5-6 but disrupts between pH 6-7.

The model shows that filament flexibility and amino acid differences affect how fast intermediate filament proteins assemble.

Hair curvature in Japanese people is linked to specific cell types and filament arrangements in the hair cortex.

AIRE protein, defective in APECED patients, is found in skin and hair cells and interacts with cytokeratin 17.

Disulfide bonds make keratin in hair stronger and tougher.

The study concluded that PKP1 is essential for skin integrity and hair growth, and its dysfunction causes the symptoms of ectodermal dysplasia/skin fragility syndrome.
