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

CD2 might be a new treatment target for patchy alopecia areata.

Keratin K80 is an ancient protein found in various tissues, important for cell structure and tissue differentiation.

A new amino acid derivative, ATS, improves hair texture and moisture, making it easier to straighten curly hair.

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

The vector successfully directed specific gene expression in hair follicles.

Hair is a complex protein fiber with unique properties useful for developing hair products.

A genetic mutation in the hHa1 gene creates a smaller, but still functional, hair protein without causing hair problems.

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

Keratins are crucial for hair strength, and mutations in certain keratin genes cause hair disorders.

A chimeric keratin partially improved skin structure in mice lacking keratin 5, but didn't fully restore normal skin.

Epidermolysis bullosa simplex causes easily blistered skin due to faulty skin cell proteins, leading to new treatment ideas.

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

Recombinant keratin materials may better promote skin cell differentiation than natural keratin.

Keratin is crucial for skin barrier formation and affects mitochondrial function.

A mutation in the KRT71 gene causes a hair disorder by disrupting hair follicle structure and texture.

Recombinant keratins can form useful structures for medical applications, overcoming natural keratin limitations.

A mutation in the KRT25 gene causes woolly hair and hair loss.

Nestin marks cells that can become a specific type of skin cell in hair follicles of both developing and adult mice.

Keratin proteins are crucial for healthy skin, but mutations can cause skin disorders with no effective treatments yet.

Keratins help protect cells, aid in cancer diagnosis, and influence cancer behavior and treatment.

Hormones control keratin production in skin and hair.

Wool keratin is reactive, biocompatible, biodegradable, and can model keratin from other sources.

Corneous beta-proteins evolved uniquely in reptiles and birds, forming scales, claws, beaks, and feathers.

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

Nestin identifies specific progenitor cells in hair follicles that can become outer root sheath cells.

Nestin-expressing cells turn into a specific type of skin cell in hair follicles during development and in adults.

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

Keratin filaments' elasticity is influenced by their terminal domains and surrounding medium.

Hard α-keratins stay stiff in water because the surrounding matrix keeps them dehydrated and strong.
