Question: is 3 in 1 shampoo bad?
Answer: 3 in 1 products do work but not as well as individual products. A 3 in 1 won't wash oily hair particularly well and it won't condition hair as well as a separate conditioner either. There's not really a lot of difference between a body wash and a shampoo. ... So you might like the way a 3 in 1 performs as a body wash.
