Actually, people looking at my hair tell me that it's really thick but when I feel it myself, it doesn't feel that way. I've just been putting on product upside down and smoothing it down my hair with a hand in the front and in the back. Somehow that works for everything but underneath. Maybe I'll try counting the back as a separate section though... that's a good idea!
I've been having trouble with the front part of my hair, the part that ends up in front of my shoulders, and the top third of my hair is getting really limp. I tried a PT today in hopes that the extra protein will give it a boost but I'm new to all of that so it's really just an experiment for now.
