Here's why:
* Change in Appearance: A haircut alters the length, style, and overall appearance of your hair. This is a tangible and visible change.
* Alteration of Matter: Cutting hair involves removing a portion of the hair fibers, changing the physical structure of the hair.
* No New Substance Formed: A haircut doesn't create a new substance or chemical composition. It simply alters the existing one.
While a haircut might be considered a temporary change (since hair grows back), the act of cutting it itself is a physical alteration.
