I bought the conditioner bar first without using the shampoo bar. But after I used the shampoo bar together with the conditioner bar, I realized how amazing my hair is using the two together! My hair is super smooth. These bars are amazing for travelling because I don't need to worry about airport security check of liquids or the bottles exploding. It's very light weight too. The shampoo bar is really easy to foam and a little can go a long way. It feels good to be plastic free!!!
