I don't know why I didn't figure this out before!!!!!!
I wash my hair in the shower and the shampoo runs down all over my whole body. Printed very clearly on the label is the following warning: FOR EXTRA VOLUME AND BODY.
No wonder I have been gaining weight!!!!
Well, I have gotten rid of that shampoo and started using dish washing liquid instead. Its label reads, DISSOLVES FAT THAT IS OTHERWISE DIFFICULT TO REMOVE.
Problem solved! If I don't answer the phone ... I'll be in the shower!
