Help! I've been using L'oreal Elvive's anti dandruff shampoo with Selenium Sulfide for years. This is the only shampoo that really helps, with all other shampoos and brands it only gets worse or it just doesn't help. Unfortunately, L'oreal removed this shampoo and the version that replaces this shampoo from the range. Does anyone have any idea if you can buy a shampoo for dandruff with Selenium sulfide in it somewhere? (Selenium Sulfide) Thank you so much in advance!
