The rinse-in shampoo was very convenient and the scent was gentle. I want to buy it again.
I keep buying this because it saves time. It doesn't make my hair dry or flaky, so I have no problems with it.
Since rinse-in shampoos aren't widely available, I decided to try this one from this manufacturer. It was cheap, so I didn't have high expectations, but it was surprisingly good. It left my scalp feeling refreshed and my hair smooth.
I occasionally need to use a treatment, but usually this alone leaves my hair smooth and smooth, so it saves time.
Good points: Nice scent. Very cheap. Bad points: None. Not suitable for people with damaged hair. Good for those who tend to get oily hair.
