Silver, I don't have any specific recommendations but my stylist, whom I trust quite a bit not to waste my money, insists that you should only use professional grade straighteners and that the cheaper ones will just fry your hair. She uses one where the heat adjusts to suit your hair texture. I have an appt. next week and could get the name for you.
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
