If you are not able to find one without the blacklisted ingredient, then we would suggest looking for one where you have the blacklisted ingredients quite low down the list. Generally, sulfate shampoos are difficult to find without blacklisting ingredients because sulfates aren't seen as 'good' ingredients outside of HQL! So, find the best product option that you can and continue looking for better alternatives. If you find one, then you should upgrade to that one, and so on, until you find the best option available for you.
