I have tried everything to get rid of Tinea Versicolor, with no success, ive used selsun blue, zinc shampoo, sulphur shampoo and sulphur soap, tea tree oil soap, defense soap, benzyl peroxide acne medication, ivarest, you name it, ive used it and none of it worked. Including a bunch of stuff for dogs and horses lol (you get desperate after a while). This is what ive done and its almost gone now - course its winter time and we'll see if it still helps once it gets warmer. First, I sleep in a tshirt now, I bathe as regular and afterwards, dust the areas with lotramin antifungal powder I found on amazon. Usually everything will help to a small degree when first using it - but then after a week or two it starts getting hold and worse again. This time with the powder, it just keeps getting better and better every day, I have also binged with chocolate and cookies and waaalaaa, still getting rid of it using this powder it did not get worse. Before, a sugar binge would screw up any progress and have me starting all over again but this powder works!! No more putting shampoo or soap on - letting it dry for 30min and then washing it off or leaving it on all day or night. Just powder in the morn and before bed. Hope this helps, I've had this for 3yrs now on my neck, chest, and armpits. My armpits were almost black from it being so bad - now btw - they are almost back to regular skin color. The powder is cheap too - 17 bucks for a 3pk. Note- I'm not even through the first bottle and its almost gone. After spending hundreds on other junk, this is my pick, down here in Southern Louisiana its humid as all hell so I am happy to have found this.
