I don't mind the ridges - as Praetor mentions, I just assume some Romulans have the ridges and some don't.
As for the uniformity of hair and clothing, I am pretty sure that was done to underline how important conformity was to Romulans. They all looked a lot alike because that was the way they were supposed to look.
Besides, just about everybody we saw was either a military officer, a secret-service-type agent, or a high Romulan official. How much individuality does one see in military officers, intelligence agents or high officials in cultures here on Earth? Speaking of my own culture (USA), I'd say "not very damn much," and this in a culture that at least at times admires individuality.
