Question: Does it include shower head?
Document: I have well water and my hair would never keep its color. I installed the filter and my hair color doesn't turn orange. The stream from the shower head has good pressure too. It was worth the price.
This is a good fit for replacement to Aquasana shower head filter and cost cheaper significantly then Aquasana offer.It seems the same quality like the over priced Aquasana filter and I suspect both use the same source for the filter.
I have replaced the filter in this system a few times before with no problem. This time, it leaked like crazy until we realized that the O ring on the shower head had come off with the old filter.....had to get the old filter out of the trash and remove the O ring from it which was tricky to get back in the right place on the shower head and make it stay.
A few dollars more to make your condition better? Allow me to put it this way; If you were my wife and my desire is to see your natural beauty? Yes, I'm buying one for each shower head in our house. And I have.Your hair will feel cleaner, your skin will feel a difference. Please keep in mind this product doesn't replace your quality hair products or skin care but it helps immensely.
We have used this filter on our shower heads before. We are satisfied with it, since we do not use a water softener.
Nice to filter shower water as well! We have in my son's shower as well so he gets cleaner water.
These are great filters, easy to install and last a long time. I highly recommend Jonathan Beauty products and especially  the shower filters.
The Jonathan Beauty Water Shower Purifucation System is a must have! It softens your skin and provides you with fabulous hair. This product arrives quickly, is packaged well. Thanks!
The Jonathan shower water purification system was ranked one of the best on a consumer website. This included the removal of lead. I won't shower or bathe my child without it and the price is not bad.
We have really bad water in my area. My and my kids' hair never felt clean. I installed the Jonathan Shower Filter and now our hair feels clean and shiny. Now I can't live without it.
