Hair and nail cells share similar proteins, indicating a common differentiation pathway.

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

Monotreme hair structure and protein distribution are similar to other mammals, but their inner root sheath cornifies differently, suggesting a unique evolution from reptile skin.

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

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

Changes in keratin affect skin health and can lead to skin disorders like blistering diseases and psoriasis.

Hair proteins have weak spots in their α-helical segments.

The document concludes that understanding the genes and pathways involved in hair growth is crucial for developing treatments for hair diseases.

The document concludes that the human keratin gene cluster is complex, with a need for updated naming to reflect over 50 functional genes important for hair and skin biology.

Marsupial hair structure and keratin distribution are similar to placental mammals.

Hair protein composition is similar across different races and shapes.

The study found that specific proteins are markers of hair follicle development in human fetuses.

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

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

Modified keratin binds better to hair, especially bleached hair.

Keratin 33A is a key protein in goat winter coats, especially in high-producing breeds.

The skin has multiple layers and cells, serves as a protective barrier, helps regulate temperature, enables sensation, affects appearance, and is involved in vitamin D synthesis.

Scientists have found a way to create hair follicles from skin cells of newborn mice, which can grow and cycle naturally when injected into adult mouse skin.

Hair problems can be caused by genetics or the environment, and treatment should focus on the cause and reducing hair damage.

Some hair loss disorders are caused by genetic mutations affecting hair growth.

Bleaching hair damages protein structure, especially keratin, leading to weakened hair.

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

The study found genetic differences related to hair development that may explain hair loss in a patient with Trichorhinophalangeal syndrome type I.
