Query: works very well. :)

I just bought this product today from ulta and had my sister do it. i was very scared to try it because i have had my hair done in a salon before and nothing really changed. and so we used it, it took about an hour and my hair is soooo much better its extemely straighter although i still do have the frizz but whatever. atleast the horrible curls are gone and i dont have to worry about it taking an hour to straighten it everyday all im gunna need to do is a nice deep condition and go over it a few times with a straightener and im ready to go! I am extremely happy that i found a product that will actually help me with me unruly hair!! :) i would def recommend this to people. as long as you do it right i dont see how it wouldnt work for someone.
