Keratin proteins are crucial for hair growth and structure.

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

Different combinations of human hair keratins affect how hair fibers form.

Human hair keratins K85 and K35 create unique filament patterns important for early hair formation.

Changes in keratin make hair follicles stiffer.

Keratin hydrogels from human hair show promise for tissue engineering and regenerative medicine.

Keratinized wool cells still have some organelles like lysosomes and mitochondria.

Different fields of expertise must work together to better understand hair growth and create effective hair loss treatments.

Human hair keratin might be good for filtering out harmful substances from water.

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

Disulfide bonds make keratin in hair stronger and tougher.

Human beard hair medulla contains a unique and complex mix of keratins not found in other human tissues.

Hair's strength and flexibility come from its protein structure and molecular interactions.

Antler velvet hair and body hair of red deer have different structures that help with protection and insulation.

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.

Cysteine-rich keratins evolved independently in mammals, reptiles, and birds for hard skin structures like hair, claws, and feathers.

Human hair keratin fibers have a detailed nano-scale structure that changes with different conditions.

An apple-based supplement was found to stimulate hair protein production, which may help with hair growth.

Keratin's mechanical properties are influenced by hydrogen bonds and secondary structure, and can be improved with the SPD-2 peptide.

Keratin-associated proteins have ancient origins and were used for different purposes before being adapted for hair in mammals.

TGM3 is important for skin and hair structure and may help diagnose cancer.

Disulfide bonds in keratin fibers break more easily under stress, especially when wet, affecting fiber strength.

Environmental factors can cause mutations in skin proteins, leading to skin disorders.

Nanomaterials can improve hair care products and treatments, including hair loss and alopecia, by enhancing stability and safety, and allowing controlled release of compounds, but their safety in cosmetics needs more understanding.

Some hair protein genes evolved early and were adapted for use in hair follicles.

Cats with abnormal hair had DSG4 gene changes causing hair problems.

High glycine–tyrosine keratin-associated proteins help make hair strong and maintain its shape.

Hair keratins evolved from ancient proteins, diversifying through gene changes, crucial for forming claws and later hair in mammals.

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