How do I fit the Hair Doctor to my Shower?
We have an easy to follow instruction video on this page.
Whats Making my water hard?
Environmental changes are leading to an increase in minerals in our water supply resulting in hard water. This is primarily due to elevated levels of rainwater, which collect more minerals as they pass through the environment and into our water sources. As a consequence of climate change, water quality is expected to deteriorate
further in the next few years, exacerbating the issue of hard water
How long does the filter last?
Typically 3-6 months depending on usage. The general guideline is 3 months if it's being used by two or more people, or every 6 months if it's just on person using it regularly.
Is the filter easy to install?
Yes! It installs in less than 2 minutes, full instructions are included.
Does the filter affect water pressure?
No! not when the filter is replaced on time. If the cartridge isn't changed as recommended, it can become blocked and reduce water flow.

Let customers speak for us
from 34 reviewsThe hair doctor filter has been a game changer for me!! My hair is colour treated and I live in a hard water area. I have a water treatment system in the house but my hair was SO dry. Since using the hair doctor my frizz and dry hair has gone! I’m a complete convert!
Love this little rush😁. New best friend, comes everywhere with me.

Best hair brush ever. Brush’s through your hair very smoothly

The condition of my hair has improved massively since I started using the hair filter last year. Prior to using it, I used have to use large amounts of hair conditioner/defanging sprays in order to brush out my hair. It was always a dried out tangled mess. It’s so much softer and healthier looking now.
My hairdresser recommended the Hairdoctor filter and I will admit I was skeptical. As I have tried so many various filters for our shower over many years, I had come to the conclusion that our water was simply too hard for anything on the market. I am delighted to say, I was wrong. My hair has been transformed to what it used to be 20 years ago but the real surprise was my daughters skin. Her acne is all but gone! I cannot believe it was our water that caused her acne for years. Also saving a lot in products both skin and hair, as I only need to use half the amount! Highly recommend this to anyone and everyone. You will be pleasantly surprised!
Great little brush. Perfect size for handbag. Brushes hair so well and doesn't pull hair. Will be ordering in the larger size

I live in a very hard water area and since getting the shower filter the water feels cleaner and I’ve noticed my hair condition improving
Very easy to install, happy that I went for this brand. Knowing it’s an Irish brand was great.
I love this, my hairdresser told me about it. My water is really bad and full of lime. From the first use I could tell the difference after using this and my skin feels softer also my hair colour is not dulling as it normally does (I am bright blonde). I will continue to use this and replace the filter when needed.
Fantastic brushes for tangled hair for small kids so delighted with them even my oldest daughter who is 14 loved them 😊

Brilliant product 👏🏻..my hair is so much softer. Noticed from first wash..only disappointed I didn't try it years ago
I would recommend this, my skin seems shinier and my skin is not dry from the hard water
