What does curly hair have a special structure?

Curly hair has special structure because it’s shaped differently from straight hair, like how a twisted rope behaves compared to a straight one.

Imagine you have two pieces of string: one is straight, and the other is twisted into curls. If you hold them up to the light, the curly one looks more interesting, kind of like when you twist your phone cord and it gets all knotted up!

Why does this matter?

Straight hair is like a smooth road, easy for things to slide along. But curly hair has tiny bumps and twists in the strands, like a bumpy path made of little hills and valleys.

These twists happen because the inside of each hair strand is built with a special shape, kind of like how a spiral staircase goes up instead of just straight up!

Because of these twists, curly hair feels different when you touch it, it’s more squishy and springy, like a coiled spring in a toy.
