Read the friggin' ingredients on a bottle of shampoo...expensive or cheap. You need to be a world class chemist to know what it all is. I think some of that stuff is used in the making of asphalt, weed killer, and probably 100 other items that are environmentally unsafe.
And we put it on our heads???????
I personally use GOO GONE. LOL
Anyone for a Weenie Roast?
