it is ok but [SEP] i have had psoriasis for about years i used the ionil t products for years at the suggestion of my dermatologist and they worked well i went to this plain shampoo no conditioner as the price started going up and used it for a long time then when the price on this stuff doubled in months i started looking around and found this deal on amazon for two oz bottles of the beta tar gel shampoo for less money than one bottle of the ionil t it is twice the strength coal tar and lathers a whole lot better than the ionil t ever did i have been using the beta tar product for about a year now and i am very pleased with the results for my scalp psoriasis check out my review at the product site
