Ooh, is scent one of your migraine triggers or did it just exacerbate a migraine that was brewing from something else? Amla isn't too hard to rinse out it's very similar to henna actually. Just rinse under the tub faucet and grab some cheap condish and go go go! lol I haven't used coconut milk in my mixes, because I like to keep them very simple. That way if I don't like what the treatment does to my hair, I have a very short list to troubleshoot.
