I have been using the scented BT on my 10 year old daughter for a little over 7 days now and believe it or not, I can actually see some growth already! The first day she complained of a headache. I read that some others on the board have experienced that side effect and I was ready to stop using it on her but day 2 she was fine and no more headaches ever since. The only problem I am having is the excessive amount of dandruff flakes I am seeing in her hair. Before starting use, I didn't see this. I am wondering if it's the BT or what my grandmother use to call "growing dandruff". Has anyone else experienced scalp flaking? It's really bad, there is no smell or soreness just large flakes. They dissapear once I apply the BT but then the next night, flake city again. She said her hair doesn itch at all either.
