Keeping hair straight?

K well, # 1 the hair spray might work after you've straightened it if you didnt comb it out. Second when you have naturally wavy hair sometimes it doesn't like to stay straight, I when I do mine its not completly straight byt he end a wave starts to form back a but (mines naturally curly), but if hair spray doesnt work .. I don't really think there is a solution. Like I said you're hair wants to do what yoiur hair wants to do, mine doesnt even stay all day when my hair stylist doest ti for me. (P.S: straightening your hair often isnt good, just saying. Learn to like YOUR hair.)
