Question: are 2 in 1 shampoos bad for your hair?
Answer: Bottom Line Despite what you may have heard, 2-in-1 shampoos do not damage hair or coat hair with layers of wax or plastic. In fact, most moisturizing and conditioning shampoos use 2-in-1 technology (even if it doesn't say 2-in-1 on the label). The truth is, these products work and they work well.
