Question: Do You Really Need to Wash Hair Twice?
I challenge you to find a shampoo bottle that doesn't contain the directions to "rinse and repeat" (or some version of that). But should you? I have to wash my hair twice because it's very thick. So I say use common sense: If you have short hair, a good initial wash will do you. If you have long or really thick hair (like me), a second coat may be optimal. Personally, I've always wondered if companies put that on the back to get you to use more shampoo.
