I'm in Australia. I started using Zeal antidandruff shampoo every day over 10 years ago. I've got sensitive skin and dandruff. Zeal used to be available in Australia, but no longer, so I order it from DermOrganic in 6 bottle lots (to reduce postage per bottle). I've tried other products over the years without success. If Zeal were to go off the market... I'm !^%$#! :-)

This has worked well for years on my psoriasis hence why I order from Australia

It is the only shampoo that has ever eliminated my husband’s dandruff!!

This is wonderful shampoo. You can feel it working when you use it. Will keep using it to take care of dandruff.

I have used Zeal on and off for about 15 years, if I run out and then forget to order more I try other products. I try to do natural, gluten free and organic and free of all the bad stuff, but nothing else that I've tried ever gets rid of the dandruff/flakes or itchiness. I finally remembered to order and I ordered 6 bottles at once so that I won't run out soon. I don't wash every day but I'm washing a little more frequently right now just to get the Zeal on my head more frequently because the dandruff and flakes and itching are driving me nuts. I've washed 4x now and there's already at least a 50% improvement in those symptoms. I really don't know why I would ever try anything else. I just have to make sure to order a bunch at a time and not wait until it's gone before I order again. Thank you for Zeal!!!
