Hiiii everyone! First time posting so work with me here.

My last relaxer was in July 2011. I've been wearing crochet braids since then as my transitioning style (I absolutely love it!) and I cut off all my permed ends in August 2012. I've been contemplating if I'm really ready to start working with my natural hair as opposed to wearing these crochets and I think I'm ready to give it a go. BUT here is my dilemma. I want to straighten it just to see what it looks like. I haven't had straight hair in so long and I'm some one who never missed a hair appointment with the dominicanas for a wash and blow. I loved it silky straight and now I'm just yearning to see if I can still achieve that silkiness with my natural hair. ...

Should I or should I not let them straighten it? It would only be this one time!!
Could this one time ruin my natural hair before I get to know it? Any suggestions for a way to safely straighten it (if that exists).
