I really believe that most stylists are completely unable to style curly hair other than straight!
Maybe he thinks that curly is too wild for the office???
I have 3B ish hair. A zillion years ago, I had it styled straight and wore it to work as such. My coworkers did NOT like it. One summed it up by saying, even though your hair is straight, it doesn't move right. Almost like it is unhappy. Like it is a wig!
That was the last time that I did that
