This may or may not help, but I have pictures of my hair with a press & flat iron. A simple flat iron won't do it for my six inches of natural hair. As far as straw sets, I want one but right now my product junkie behind won't allow me to so I used perm rods (the tiny pink ones). I did an experiment with only a couple of them (in my album) but recently redid my whole head with about 40 of the rods and it came out great. I had tiny curls and it didn't look frizzy at all. I don't know if I should attribute that to using my own concoction of spray rather than using a setting lotion or because I slept in some uncomfortable positions to keep my style but it didn’t frizz up and it’s been 3 days since I’ve had my hair in this style. On another note I just went to a concert and saw a friend of mine with natural hair who had a straw set. I didn’t ask her how long she has had it in but the curls were in tack, however, her roots weren’t. You could still tell it was a straw set but it looked as though it was mixed with a little jehri curl as well. I don’t know if the results are the same for everyone, but I HTH.
