In my opinion, so long as you pay and tip the stylist for the freshly styled hair, he/she probably could care less about what you do to it afterwards. And if they do, I'd be worried about whether they're also going to be overly sensitive to any constructive criticism. After a few bad stylists, I finally settled on one that respected the fact that it's MY hair and MY money. While I respect her and her work, her ego should have little to do with it.

As you continue to work with this new stylist and get comfortable with a particular cut/style, then you might just admit to him that you don't need him to really do a full style at the end because you're cycling home. My stylist will often ask me what I want her to do stylingwise. If I'm just going home, she'll often just blow it dry and leave it at that.
