Step-by-step explanation:
The reason we have to constantly clip our nails is for the sake of cleanliness. Nails can be a carrier of bacteria, and can easily get people, and the carrier, sick. Have you ever seen a cat scratching at a chair? They do this to clip their nails, just like us!
We don't necessarily have to cut our hair, but if you keep your hair too long it can be a hassle. Cutting your hair can get rid of split ends, and overall, just make it look better and easier to manage.
