Thanks for emailing Devachan and posting the response on the forum. I will email them as well (sorry have been o/s) so maybe they can know there is interest downunder...
cccurls - thanks for the recommendation. I'll give them a go and let the forum know how it went for me as well (different thread tho). I hope it's okay, but I've also reposted your recommendation in the 'sydney hairdresser' thread so ppl googling it can find it.
