Texturizing is like giving your hair a haircut that makes it look less flat and smooth. It's like if you take a piece of paper and crinkle it up, you get more texture on it. In hair, the hairstylist can add different layers or cut it in a certain way to make it look more interesting and less plain. Texturizing can also make your hair easier to style because it isn't all the same length. So, it's like if you had a bunch of play-doh and you made different shapes with it instead of just having one chunk of play-doh. Texturizing can also help make your hair look thicker or thinner depending on what you want.
