50 Facts About Keratin

What is Keratin?

Keratin is a protein found in the cells of your skin, hair, and nails. It serves as a protective layer and helps maintain the structure of these tissues. Let's dive into some fascinating facts about keratin.

1. Keratin is a fibrous protein that forms the structural framework of your hair, skin, and nails.

Hair is one of the most noticeable features where keratin plays a crucial role. It not only gives hair its strength but also its elasticity and shine.

6. Hair follicles produce keratin through specialized cells called keratinocytes.
7. The shape of your hair (straight, wavy, curly) depends on the structure of keratin proteins.
8. Keratin helps protect hair from damage caused by heat, chemicals, and UV radiation.
9. Hair grows approximately 0.5 inches per month, thanks to the continuous production of keratin.
10. Keratin treatments can temporarily alter the hair's structure, making it smoother and more manageable.

Keratin in Skin and Nails

Keratin isn't just for hair; it's also vital for the health and appearance of your skin and nails.

11. The outermost layer of your skin, the epidermis, is rich in keratin.
12. Keratin helps form a protective barrier on the skin, preventing moisture loss and shielding against pathogens.
13. Nails are made of hard keratin, which provides strength and durability.
14. The growth rate of nails is influenced by the production of keratin.
15. Keratin in the skin can help heal wounds and regenerate new skin cells.
