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.

Disulfide bonds are crucial for hair structure during keratinization.

Oxidation changes the structure of hair protein filaments, causing them to compact and rearrange.

Hair follicles form hard α-keratin filaments in four steps, showing structural differences.

Scientists successfully created mouse hair proteins in the lab, which are stable and similar to natural hair.

Trichohyalin is a versatile protein involved in hair and skin structure.

Intermediate filaments are crucial for cell differentiation and stem cell function.

Keratin structure changes during keratinization, but the exact model remains uncertain.

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

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.

Keratin proteins are crucial for hair growth and structure.

Trichohyalin helps in hair and skin cell structure and function by binding calcium and linking proteins.

Giant axonal neuropathy changes the structure of keratin in human hair, making it stiffer and stronger.

Disulfide bonds make keratin in hair stronger and tougher.

The study revealed the detailed structure of a keratin dimer, aiding understanding of how intermediate filament proteins function.

Human hair keratin has a 40% α-helix structure that changes to a random coil in 8 M urea.

Mice with extra sheep genes had hair that fell out and regrew in cycles.

Researchers isolated and identified structural components of human hair follicles, providing a model for studying hair formation.

Hair curliness is due to uneven distribution of different cortices within the hair fiber.

Keratin heterodimers are preferred for their specific and structural advantages.

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

Keratin-associated proteins help link filaments and affect keratin's strength.

Oxidized trichocyte keratin has a helical dislocation in its structure.

Trichocyte filaments have a low-density core and may include proteins for hair structure.

Human hair has a new region with ordered filaments and the cuticle contains β-keratin sheets.
