I’ve saved literally a couple thousand+ dollars and a shit load of time by cutting my own hair.
Buzzed is easy mode if you’ve got the head for it (definitely NOT a good look for everyone, so proceed with caution).
Actual styles are doable by feel / with a double mirror setup, but that ofc comes with a learning curve, and it WILL look janky until you get a feel for it.
I spent $30 on an electric clipper over 15 years ago - paid for three haircuts since then, which were all mandatory purchases in basic training. Easily the best $30 I’ve ever spent.
Also, super short hair takes like two drops of shampoo per shower, so if you go the buzzed route, you’ll save a lot on hair products too.
