{"response":"{\"What is hair made of?

Hair is made of something called protein, which is like the building block of your body, just like bricks are the building blocks of a house.

Imagine you're building a tower with tiny, strong sticks. Each stick is made up of little strings that twist together tightly. That’s kind of what happens when protein forms into something called keratin, a special kind of protein found in hair, nails, and even your skin!

Underneath your skin, there are tiny factories called hair follicles, where new hair starts growing. These follicles work like little chefs baking bread: they mix together the right ingredients (like protein) to make long, strong strands, that's your hair!

As the hair grows longer, it pushes up through the skin and becomes visible. It’s like a rope being pulled out of a box, you can see more of it as it comes out.

So, every time you brush your hair or tie it in a ponytail, you’re playing with protein that was made inside your body, just like building blocks for your head!
