I can't recommend as mine is probably midback now (I haven't pressed it out completely and put it in braids. ), if not almost there. So anyways regardless of the amount, make sure you have enough on your end and on your roots so your hair does not revert. Well I'm speaking from a natural standpoint and don't know if you're relaxed or if you just flatiron your hair. Either way, make sure it protects your ends. I always take a little more, after I've brushed it through with my denman, and put it on the palm of my hand. as I part my hair to flat iron. I dab a tiny amount in between my index finger and thumb and press on my roots, and then on my ends for double protection. I do this throughout. Sorry my avatar shows my press after 5 days of rain, so you can't get the full effect unless you look at the original sabino thread to see my results on day 1. I just wanted to give you these tips so your hair can stay flat iron perfect until your next wash (and your ends stay protected).
