Is it a problem that I always shower with dog shampoo?
Do you think that dog shampoo is better for your hair?
No, there was a sale going on at the store.
I see you like to save money, but you shouldn't sacrifice your well being to save a buck. Dog shampoos aren't made for human use and could irritate your skin. Stick with human formulas in the future.
What's wrong with saving a buck? I wash my body with dog shampoo and my hair with cat shampoo.
Shampoo isn't that expensive that you need to do this. Look for better deals but try to buy things made for humans.
