You definitely have to use conditioner after shampooing.

I am currently using a shampoo bar.

It was stiffer than I expected.

I haven't bought a treatment bar yet, so I'm using the conditioner I have at home.

It definitely becomes softer and my hair tangles less.

I assume everyone makes sure to use conditioner after shampooing, haha.

I think it would be even better if the product also had a nice scent :)
