The Great Shampoo Experiment (Selsun Blue vs. Nizoral)

The Story
I bought Selsun Blue first because it was $8 and said 'Maximum Strength' on the label. I'm a simple man — I see 'maximum strength' and I buy it. It works. Your dandruff will cease to exist. But so will any joy associated with washing your hair, because it smells like a selenium mine and turns your shower blue.
Then I bought Nizoral because it kept showing up in every dermatologist recommendation list. 78,000 reviews. Ketoconazole targets the actual fungus that causes most dandruff. You only use it twice a week. It doesn't stain your shower.
Here's the plot twist: I now use both. Nizoral 2x/week as maintenance, Selsun Blue when things get serious. This is probably more research than most people do on their dandruff shampoo. It's definitely more research than I did on the Zelotes gaming mouse. Priorities.
The Lesson
Nizoral 2x/week is the dermatologist move. Selsun Blue is the nuclear option. Own both.
