It's not usually needed, but if I'm really sweaty and sticky the first washing removs dirt, and the second washing adds "squeak" is the best way I can put it.

It just feels cleaner. I assume it's because the additives in the shampoo become overloaded on the first use, and are active on the second.

I like the squeak too. I recently moved to a place with hard water and so everyone has water softeners. With this super soft water I can't get the squeak ever. It just feels slimy to me.
