I just looked at your Fotki - cute BC! It suits your face so well!
When I BC'd back in 1999, I had my hair cut down very low, and the stylist used scissors. As my hair grew in it was very curly and shiny. I didn't use very expensive products, I was a poor college student, but my hair was rarely frizzy.
Fast forward to 2001 when I BC'd again after some damage, and I went to a barber who just chopped all my hair off with clippers. The hair grew in much tougher and it was frizzy all the time.
I think that they way your hair is cut has a lot to do with the frizziness you experience after. I have sported the TWA look for YEARS, and I've learned that unless I am working with someone who can use scissors well on curly hair, the grow out process is going to be long and arduous.
Frequent DC's will help, but not more than dustings to keep your ends from being blunt.
