What are keratin filaments?

Keratin filaments are tiny, strong threads that help make up parts of your body like your hair and nails.

Imagine you have a super-strong rope made of lots of little strings tied together tightly, that's kind of what keratin filaments look like inside your skin. These little strings work together to give your hair its strength and your nails their hardness. They're like the building blocks for things you touch every day, such as your fingers and toes.

Think of your hair as a rope made of many keratin filaments twisted around each other. When you comb your hair or tie it up, those tiny strings are working hard to keep everything from falling apart. The same goes for your nails, they're like hardened ropes that help you scratch things or pick up small objects.

Without these little keratin threads, your hair might be more like spaghetti, and your nails would be as soft as a banana peel!
