I was worried about scalp odor so I read reviews and bought this! It turned out to be the best for me! I saw on YouTube that you shampoo once, massage your scalp with jojoba oil, and then shampoo again, so I tried it, but shampooing twice is a bit of a pain, so with this, I can just wet my hair, massage the scalp, and then shampoo, which is really helpful! It also gets rid of scalp odor and leaves my scalp feeling refreshed. The price is pretty good, so I wonder if it's worth it to continue using it. I'll use it as a special treatment once a week. But I'll definitely buy it again when I run out lol
