okay first of all..chemically relaxing your hair is not all that dangerous. I have done it twice and my hair is still with me. I just make sure to condition it well before and after the procedure. My hair is just like yours. It's flat on top and then it starts to curl like a telephone cord towards the end. What I do is I take a flat iron and flatten the curls at the bottom so to make it less curly. My hair ends up having sexy waves that frame my face. Guys love it. The key to curly hair is to make sure it is moisturized well. It gets rid of the frizz. Keep the travel size leave-in-conditioners in handy so your hair can be replenished with moisture throughout the day. good luck!!
