Good afternoon, Yesterday I went to a wedding and decided to try to press and flat iron my hair which I did and it looked nice in the house, but once I began to sweat on my way to the wedding my hair was no longer straight (it was a pooooofieeeee mess). Would it be possible for you to give me some tips such as which products you use, how you do your hair, etc? I wanted to wear my hair in a lot of curls but that did not work out. Is it impossible with natural 4b hair? Thank You .
