In the late '70s, mom started buying Agree hair conditioner. I started using it, but I thought it was shampoo. I had no clue that shampoo and conditioner were totally different things. I used it for about 2 weeks as a shampoo until I caught on. The kids in school were raggin' on me because of my greasy hair (although in their defense, I have to admit that for awhile there my hair was lookin' pretty skanky...)..
