Definitely sounds like a go! I have given up shampooos with SLS but still use shampoo from Helth Food store. I am not having much problems with my hair but then again, I am cleansing my body and that seems to help.
I will try the olive oil treatment and see if it doesn't help hair along! I still in need of using 'products' on my hair as that it is sooooooo fine and doesn't seem to have any oomph! I am letting it grow back out, got it cut short and it is now in an in-between state. When it gets to where I want, hopefully I will notice it more manageable!
