It doesn't make much of a difference.

It was so easy to install. If the water quality is damaging for your skin you should invest into this product! Game changer!

Looks good, brushed stainless steel & easy to fit. Will have to wait until after my next colour do in hairdresser to see if it protects well against fade, but combined with shower gel from Hello Klean gives nice effect on skin.

Been using with over a month now and I haven't noticed any difference in how my skin and hair feel and look. A lot of claims made with this one, but sadly doesn't live up to the hype. Installation was easy though and it doesn't look tacky in the shower compared to other filters I have used. Sadly It is an expensive ornament

Have blonde hair and have noticed a difference
