I've only had it straightened once in my life. My sister a 3A, did it for me on a visit to my hometown ( a very dry place, or it never would have worked.) It took 45 min and when done my hair reached almost to my waist. It made me look very, very different. My BF didn't like it it at all. His comment was, "it looks pretty, but it isn't you at all. It'll go back won't it?" And the next day it was already poofing out, even through layers of cone serum. I can't see doing that again. I'd try wrapping if I wanted a fun day of straight hair.
