Its ultimately your decision. But if you do, please use a silicone beforehand for protection, then you'll have to clarify on your next wash. One time in a long time with the right protection isn't going to absolutely kill your hair. But if this is a more frquent ordeal, I wouldn't recommend it. Depends where your hair is at health-wise and if you're OK with doing this. It is possible to harm the curl pattern. Once I grew a lot of my "straightener hair" out, my curl pattern went from a 2b to a 2c and 3a in spots.
2c-3a - med-coarse - normal-high porosity - high density
