What I fear was going to happen...happened! I'm surprise I'm not even upset. I knew I was going to lose a lock, and maybe even more, until I get the thinning of my hair under control. I talk in detail about my issue here.
On the right is the lock that I lost in the section where my hair is starting to thin out. I also included pictures of my hair - even though it doesn't look like I lost anything, or that my hair is thinning. I'm just fighting this issue before it becomes a big problem and I end up losing all of my locks.
