Long ago, I used Head and Shoulders shampoo. I’d been using it since I was a kid. There was only one version. Then they stopped selling the original, and replaced it with a choice of “for Oily Hair” and “for Dry Hair”. I have normal hair. I found another brand of shampoo.
“I found another brand of shampoo”
They still sell ‘normal’ head and shoulders. Blame your store for not stocking it.
