That $3 bottle of “Ocean Breeze” detergent is not your friend. Most shampoos are full of sulfates—little chemical ninjas that strip every molecule of moisture from your scalp. Sulfates are why your scalp feels like a desert after washing.
Switch to a sulfate-free shampoo. It’s less foamy, but foam is just marketing. You want moisture, not a bubble bath. Also, don’t shampoo every day. Your scalp needs a break to produce its own oils. Aim for twice a week—and if you sweat, just rinse with water and condition.
