0.5mg per day inhibits such a high percentage of 5AR that I doubt the small increase in inhibition a 1mg/day dose would produce is likely to have a significant effect on your hair.
I'm not sure how long you've been taking dutasteride, but if you're still quite early on you may want to take a larger dose (eg. 1.5mg/day) for a week or so to jump the level of Dutasteride in your system up towards the maximum attained from a daily .5mg dose. Much like the pink line in this graph: http://www.hairsite2.com/images/dutas_analysis.jpg
