The itching was reduced by 50%, but that's about it. I was expecting something better. As for the odor issue, there was no difference, it remained the same. I will try another product.

Due to an itchy scalp, I ended up using this shampoo and have been using it for the past few years. Odorless, colorless, "tasteless," and effective. I initially had some concerns because I have dyed hair, but luckily it doesn't fade them.
