I went from shoulder-length to short last year and honestly don't regret it at all! The key is finding a style that works with your face shape and hair texture. With thick hair, you've got lots of options since you won't have to worry about it looking flat. I ended up going with a gentleman's haircut that has a bit more length on top and shorter sides - gives you versatility without being too drastic of a change. You can style it sleek for formal occasions or messier for casual days. The maintenance is so much easier too - my morning routine went from 20+ minutes to about 5! Just make sure you find a stylist who listens to your concerns and can recommend something that suits your features
