@boyff sounds like a plan! a few other things which might help keep it in better condition.
Silk cap and or silk pillowcase for sleeping (this keeps the moisture in and limits breakage).
Try loose (silk hair ties) protective styles are night as well, eg looseish plaited pigtails not tied too tightly at the bottom.
During the day try not to have hair exposed to sun and wind for too long, hats and protective styles are your friends
Get a good scalp treatment, healthy scalp, healthy hair.
Avoid direct heat styling as much as possible, maybe work with your hairdresser to get a cut you are happy to wear natural/with minimal styling (this can take a few gos)
Philip Kingsley elasticizer is great get a big bottle of this if you can afford it. I think original is best
last (and worst of all)- avoid bleach altogether. I’m not saying it’s impossible to keep hair healthy when it’s bleached but it’s definitely not easy, hard enough to keep it healthy without colour when it’s long. Could you give your hair “seasons” so it gets a break occasionally?
