While my hair does okay with most shampoos, I really like the ion. I can't use it too frequently, as it is tough on your hair in order to lift the iron buildup and muck that gets stuck in your hair, but it does a great job a couple times a week to reverse some effects of well water usage in the shower. Effectiveness While it does a great job for those with hard water and well water systems, I live in Indiana and our well water is very hard, along with humid summers. I find that this shampoo sort of dries my hair out if I use it too frequently, and I have to counter-attack it with a deep conditioning treatment if I have to use it too often. It's definitely worth it in that it gets rid of the buildup in my hair, but it's most certainly not a daily or bidaily shampoo. Scent I never really notice a scent with this shampoo, which is fine with me. Scents from shampoos and conditioners don't stay in my hair anyway, so fragrance free is perfect.

I just move to Houston from California and my hair was always tangled, I bought the Ion leave in conditioner for hard water and I had an instant change.  However, I have noticed that some of my hair does fall out. It could be because of the wheather change though.
