Selenium Sulfide Anti-Dandruff Shampoo.

"My next favorite ingredient to look for is selenium sulfide. This one can be stinky sometimes, but I absolutely love the efficacy of it. It works by slowing down the yeast overgrowth and reducing inflammation within the hair follicle. This can be especially helpful for people whose fungal acne flares when there is sweating and humidity. A common brand I love for here is Selsun Blue. You can also get the Niserol shampoo in the navy blue bottle. And just like shampoo, this can be used as a short contact wash rather than a leave-on product. Apply it, let it sit 3 to 5 minutes, then hop in the shower and rinse it off."

"Selsun Blue is the most popular selenium sulfide shampoo here in the US, and it's my go to first line treatment for tinea versicolor. The selenium sulfide is an antifungal ingredient that helps get rid of the overabundance of that yeast. Given everything I've said about the protocol, it can work, it is well established to work, though for a lot of people it doesn't work because they weren't properly counseled or didn't do the protocol correctly. It's rather involved and a lot to keep up with, but I suggest doing it once a week for at least three months, and bringing it back into your shower routine once the hot humid months approach."
