I always had an idea of what my hair textures were like because I would stretch my relaxers (8 -12 weeks). Therefore, I knew about the variances in texture and thickness but nothing prepared me for what I discovered when I BC'ed!
I transitioned for 15 months by rollersetting my hair bi-weekly and I gradually got the relaxed ends trimmed off by a stylist every 3 - 6 months. During my transition, I found out that the hairs around my hairline (front and back) were finer and had a looser curl pattern than my crown area. I also discovered that I have more hair on the right side of my head than on the left.
But when I BC'ed (self-chopped, Feb '09) I didn't realize that my relaxed ends were stretching and weighing down my natural hair. So when I was done cutting my hair, I ended up looking like I had a jacked up, DRIED up geometric afro
Needless to say, I was not loving the look - neither was my husband
But I committed myself to not rollersetting my hair after the BC just so that I could figure out how to style and maintain my natural hair. It took me two and a half months after my BC to see my hair textures "clearly" defined with and without haircare products.
BTW, I have not straightened my hair in almost a year, y'all!
Good luck to you, Cheezy, and all the other ladies trying to transition.
Try to enjoy the process.
