This might be a long shot for you, but my hairdresser told me that grapeseed oil is absolutely fabulous to condition hair, as it will enter the hair shaft itself (I think it is called the cuticle). Just go to your health food store and get a bottle and put some in a little dish about 4 or 5 tablespoons and heat it up on a very low setting for about 30 seconds in the microwave if you care to or not, and then put it on your hair and wrap a damp towel around your head and give yourself a manicure while you are waiting. I'd leave it on for about 30 minutes and then shampoo. I've heard that olive oil will do the same thing, but some people disagree with it and say that olive oil doesn't help. I think it does for my hair, and I am a bottle blonde.
