Amodimethicone is the total opposite. I haven't seen build up since using a product with it.
3a/3b thick coarse WL dark brown hair. CG/Mod CG since: 5/4/05. Current products: Right now my hair is in such a tizzy over this winter weather we are hving that nothing really seems to be working. I need a haircut.
