I totally understand wanting to see your hair straight, especially with it being in protective styling for quite some time. First off yes fortunately there are some safe ways to straighten hair! However it takes quite some preparation to ensure that your hair will stay healthy and return back to its natural state once it has been flat ironed. One thing that is essential for safely straightening curly hair is HEAT PROTECTANT! And if you are going to be letting someone else do your hair, make sure that either they or you apply some form of a heat protectant throughout all of your hair. Another thing to be mindful of it that hair burns at approx. 450 degrees Fahrenheit so you may want to request them straightening it at a medium heat rather than a high heat, especially since you aren't to familiar with your natural hair and for your first time you'd be safe rather than sorry. I hoped this helped!
