Hi,
I am currently doing the elimination diet for behavioural issues etc for my daughter, part of it includes using sensitive washing powders.
I was recomended the OMO sensitive, Planet Ark, Lux or the Amway washing powder.

We haven't had any issues with the OMO but by the sounds of things a lot of people are having issues. I only use 1/3 - 1/2 of the recomended dose.

Hope you have found something that works.

Sjl
