GOOD but may not solve everything!
Used the second shower head after trying another one to try and help with my hair loss (the other one was from a different company and awful). My hair was still falling out but it did feel somewhat softer and my skin was less itchy after getting out. This one tested and it showed chlorine removal (unlike the one that didn't work), but it didn't fix everything but it was so worth the buy for the benefits it did achieve.
