Why does only selenium sulfide work on my dandruff?
I’ve had dandruff all my life. Most people (including me) have mostly ignored it, but my dad is a clean freak (he showers 2-3 times a day) and always points out the flakes on my shoulders when he sees me and buys me Head and Shoulders shampoo. It never works. I’ve been using Head and Shoulders all my life. My dad thinks I’m not using it whenever he sees me. “You still have dandruff?! Why aren’t you using that Head and Shoulders?”
I am. It never works. Anyway, I decided to see a dermatologist a couple months ago. I explained all this, and she prescribed me some medical grade shampoo. 2.25% selenium sulfide. Surprisingly, it actually worked! I came back a month later, and no flakes! She said I had some special sort of dandruff; I can’t remember the exact name. “Don’t go too far down the rabbit hole,” she said. Weird suggestion, but whatever. I googled “selenium sulfide,” and apparently the consumer brand is Selsun Blue. Head & Shoulders doesn’t even contain any selenium sulfide. So now I’ve been getting Selsun Blue shampoo instead of Head & Shoulders. I’m not sure why it works better. The only problem is that the Selsun Blue only has 1% of the SS instead of 2.25%.
Since I never actually notice the dandruff myself (it never itches or anything), I can’t really tell if this weaker, generic brand is working. Maybe I should FaceTime my dad and see if he can tell.
Can anyone here tell a difference? If I just squirt a shit ton on my head, will it do the same as the prescription grade?
