I would take his opinion into account yes, and if he really disliked it I probably would, in all honestly. I don't think that makes him controlling or anything, just ultimately if he really didn't like it then I'd probably go off it myself.
On the flipside, my OH has long curly hair and has deliberated cutting it off several times (particularly in the hot weather we've been having) and I asked him please not to as I love his long hair, and he didn't. So it works both ways!
