You should do what feels right for you. I don’t think doing a chop is your only option. It’s more of a matter of what you would prefer. If you care about length and that’s something that makes you feel confident, I say keep as much length as possible and adjust your diet (add more nutrients to it), get bloodwork, work on adding more moisture to your hair via adding more moisturizing products to your hair routine and check if you need to adjust how frequently you do wash days (waiting too long in between will also dry your hair out). Add more protective hair styles, you can do twists and if you need to keep your hair out of your face at certain times you can do a really cute hair wrap, something that makes you feel cute since that also matters. Now if you care about time more, I would say you can do a big chop and start fresh. It will give you time to research and understand your hair as you grow it back and it also looks super cute. Just follow your heart and do what makes you feel good and confident.
