What was name of shampoo in black square bottle?

I have been trying to figure out the same thing!

In the early 1990s I used to use a shampoo and conditioner that was sold in black, shiny square bottles. It smelled GREAT and worked so well. Very unusual smell, almost like watermelon. I've been looking everywhere online just to find out the name or company who made it. I know it is no longer made, but I'd just like to know its name. Anyone! Can you help solve the mystery?
