I'm also considering a cut. I get bored really easy lol and this SFL heat doesn't help. My hair grows pretty quick so I don't mind cutting it. I say go with what will make you happy.
One thing I always consider when cutting my hair is enough length to tie my hair back. Most of my days I have it in a bun. Right now I have it close to my waist so I'm thinking for my birthday cutting it to my shoulder. Can't wait
