This an interesting question because if you check these words in a dictionary you will see that 'fuzzy' and 'frizzy' can be synonyms when talking about the texture of things, and I think there is an argument that people use 'fuzzy' for shorter lengths of fibre and 'frizzy' for slightly longer lengths. However, you will rarely hear anyone using the term 'fuzzy' to talk about hair. We almost always use the term 'frizzy'. I think this might be connected to the fact that we used to refer to people from various parts of Africa as 'fuzzy-wuzzies' - and this term is informal/offensive/racist.

Thank you, katherine, Joni and Chris for your answers. I got the idea.

I would use fuzzy to talk about a cute baby animal that was soft and fuzzy, but not a person. Or I might say that a peach or piece of fabric (something with a plushy texture) is fuzzy. For people, it's ok to use frizzy to talk about your own hair. But it could have some negative connotations that the hair is out of control or damaged, so I would probably not use it to describe someone else's hair.

Hi! Frizzy is a term used almost ubiquitously for hair. It means the hair is static and unruly. It was popular in the 80s to have frizzy hair. Fuzzy, however similar, has a slightly different meaning. Fuzzy means "not clear". If you are not wearing your eye glasses while driving you might say that the traffic lights look "fuzzy". You may also use fuzzy metaphorically. "My memory of last night is fuzzy" means that you do not remember the events of last night very well. The memory is unclear. Fuzzy is not used to describe hair very often. I hope that helps.
