Thanks Wylie! I've tried olive oil before also. My daughter and I actually got headlice from some relatives who didn't think it was necessary to let us know it was going around and we used olive oil every 3 days to treat that. It really didn't seem to help the flakiness for me though, but it may be worth another shot.
I tried the tea tree oil because I read online that it would help because it is a natural antiseptic. I also noticed that if I go a day without washing, it actually makes it more itchy! Which made me think it wasn't an issue of dryness...I don't know, it's getting so frustrating!
I'm going to try the omega supplements you suggested though, it definitely can't hurt at this point! lol And if this doesn't help, I'm definitely ready to talk to a dermatologist about it!
