Breakage

My hair is sooo dry. I did a d/c for about an hour yesterday with Herbal Essence and grapeseed oil. I rinsed it out and went to bed without a scarf. When I woke up, my hair was sooo dry, so i put some JBCO on my hair but it still felt dry. I took out my cornrows and found that my hair was so dry and was breaking. As I was combing it my hair just kept breaking. Anyway, i liberally applied some generic caster oil, hope that helps.
