I live in Az and our water is awful - it's full of calcium even with the best filters. I live in apartments and usually they provide water treatment/softeners Lately, I noticed very dry skin after a shower and to my shocking surprise a large clump of hair down in the drain. I knew if I wanted hair and moisture in my skin, I needed to place a filter on my shower. I looked and Seychelle had the perfect head. I read other reviews and it stated how easy it was to install. Yes, it was very easy to install and yes, I now have skin that is moisturized and hair that has stopped clogging up my drain. Thank you Seychelle. !!
