so this really works? is it actually worth the 150.00? My mom and I are looking into getting this. We're thinking about trying the two week trial for 14.00. I really hope it works. My straightening iron is good, but I'm sick of the lack of volume in my hair. I have naturally wavy, very thick hair, and i could wear it naturally if it wasn't for all of the frizz. My mom on the other hand has ver straight lifeless hair. Has anyone tried it with these hair types?
