Chemical Straighteners

I have curly hair and a few years ago I decided that I wanted bangs(bad choice). I got just my bangs chemically straightened and it lasted for about 2 days. I've never found anything that works so well that you don't have to put in at least 40 minutes of time to straighten. However, I have a friend who's very good with hair and straightened it REALLY well! I couldn't believe it. What she did was she took a large boar bristle round brush and blow dried my hair when it was damp, using the brush to smooth it down. She did it in small sections and when she was finished it did look wavy and frizzy. Then she just used a hair straightener on my dry hair and it got really smooth and shiny. The only products she used was a little hair gel, and only after she had finished styling it. It's this stuff called Wet and it's by Sebastian. I use it when I wear my hair curly too because it's flexible yet still holds. I hope this helps. I think the secret is in the straightener but I have no idea what brand it was. We were also out west so the dry air probably helped with the humidity and that would probably also alter the results. Good luck!
