Hi, I use Pyoben. It works wonders for my little boys. The secret here is to shampoo the pet until the shampoo is white and lathery... then rinse off - do this 2x and rinse. If the condition is really really bad, then do the very same thing 3 days later. You can wash the baby as often as necessary - and the little one will feel SO MUCH BETTER no more itching. It's a little pricey - but it is soooooo worth it.
Let me know how it works!
