I noticed a lot of hair wasn't falling all around me on the floor (to my surprise) and when I looked in the mirror, I was totally shocked! So apparently my hair did grow since January. It wasn't a farce.
Now what have I learned? It's okay to get professional help periodically, and blow drying before trimming works for me. (I don't even own a blow dryer.) I also learned that taking care of your hair while in twists or braids is really important.

Now, I think I'll do some two strand twists.
