Recently moved to an area with hard water. Wife and I were noticing more hair loss while showering. Turns out an ingredient “EDTA” can help remove buildup from hard water that damages hair. This is a common ingredient in expensive shampoos but it’s also in Head and Shoulders. Wife started using expensive shampoos to help and I switched to Head and Shoulders. She just ended up using my shampoo(much cheaper) and it’s been working well for us. Hope this helps others.

Knowing the German pronunciation makes it not as funny. But seeing “extra dick burgers” at the store still gives me a chuckle.
