There's two ways to look at it: short hair requires cuts more often, but longer hair requires more maintenance. Conditioning, trimming split ends, etc. the longer your hair is, the more obvious it is when you're not taking good care of it and it'll look like crap very easily. A lot of people grow out their hair thinking it's less work, but it's not.
Right now, Mr. Z is in a similar situation. When we were first dating, he had long hair, and it looked great. Shiny, thick, no split ends, and had layers from whatever his previous short cut was. Because of Covid, he hasn't gotten his hair cut in over a year and 1/2, but because of age, his hairline isn't what is was then, he sometimes forgets to use more than shampoo, and it's got a lot of split ends. It's not as flattering as it used to be on him, and I really wish he'd find a new stylist to give him a more flattering cut. It honestly ages him more than his short hair did.
So, it's really up to you, and how you feel. I don't remember your line of work, but if it involves you having 12 disciples, I think you're good to go!
