I did a google search on this "brain balancing" method after reading about it here - and found it was denounced as a fraud with no scientific basis. Maybe it helps some people but I would warn others to be careful, especially if you are being asked to part with a lot of money. I don't believe there are any miracle cures for trich and after many years searching I am suspicious of people who claim to have found them.
But it's great if a little girl got better. I'm just a bitter old woman in her thirties with trich, chronic depression and dyspraxia and not much hope of it ever improving. So I apologise if my message is discouraging. I've been too many times by treatments which promised to transform my life and didn't.
