I do agree with Plan9 that shaving doesn't actually make hair grow in thicker.
It can, however give the illusion that hair is thicker, since the hair now has blunt ends, instead of tapering off. :edit: Also, hair grows in stages, so shaving may cause more hairs to be at the same length at the same time, making it appear that shaving caused it to grow in thicker, when in fact those hairs would have grown in anyways.
Strangely enough, though, all though middle school/early high school, I was clean shaven except for a peach fuzz mustache. Now, I've grown it all out, and everything that I repeatedly shaved is thick, red, and long...the mustache is no longer peach fuzz, but it's still very soft and much thinner than my beard (which is curly). Also, right around the edges of my mustache (where the goatee and the mustache connect to form what I believe is called a Van Dyke), I rarely shaved...and it's never grown in...strange.
Anywho, best bet is just to grow it. It may never be thick, or it may just take a while (both in aging, and just allowing it to grow in more).
Good luck.
