Work appropriate haircut? Need advise please!!!!

So, I have thick and slightly wavey shaggy hair. It looks like this I just got a job as a cosmotologist at a drug store and was thinking of getting it cut. I always lile to start a new job with a new look. About three weeks ago it got I cut and colored very dark black. Since then, and maybe it's just me being super parinoid, but I feel like more hair has come out when I shampoo it and that my scalp is showing more than usual at my my parts. Anywho, this is how I was thinking of getting it cut. Yes, I know that's a dude, but I love the style regardless. So what do you guys think? Keep trying to grow it out, or start fresh? I just want to make sure that it would be a work appropriate style, like, I know that there's a bit of wiggle room since it I am a beauty advisor and we are encouraged to show creativity and what not, so I was curious what you all thought.
