Although Finnish tap water is clean and potable, it is rarely your hair's best friend. Every shower leaves an invisible mark on your hair: minerals, chlorine, and metals from old pipes accumulate in the hair. Over time, these build-ups make hair lifeless, dry, and difficult to manage.
Not even the most expensive shampoo can fix a problem whose cause is not in the hair but in the water. If your hair constantly feels coarse and tangled, or a new color fades in record time, the culprit is likely in your shower.
Hair's invisible enemies: Limescale, chlorine, and metals
Shower water is full of substances that are invisible to the naked eye but wreak havoc on hair and scalp. When you identify these invisible enemies of your hair, you will also know how to fight them.
Hard water and limescale build-up
Although Finnish water is generally soft, there are significant regional differences – especially well water can be hard. Hard water contains abundant salts of calcium and magnesium, better known as limescale.
When hard water and shampoo meet, an insoluble film forms on the surface of the hair. This limescale build-up:
-
Prevents conditioner absorption: The film blocks the hair's surface, preventing conditioners and masks from penetrating the hair. The hair remains dry internally despite quality products.
-
Dulls and coarsens: Mineral build-up makes the hair surface rough, which prevents light reflection. The result is dull and lusterless hair.
-
Flattens and weighs down: Build-up adds weight to the hair, takes away volume, and makes hair feel dirty even immediately after washing.
The drying effect of chlorine
Chlorine keeps tap water clean of bacteria, but it is a harsh substance for hair. As an effective oxidizing agent, it removes not only impurities but also the hair and scalp's natural, protective oils. The scalp begins to dry, itch, and flake. Hair becomes brittle and prone to breakage. Color-treated hair is particularly affected, as chlorine mercilessly fades color pigments and shortens the time between salon visits.
Metals leaching from pipes
Small amounts of metals continuously leach into the water from old copper and iron pipes. These metal ions attach to the hair and initiate an oxidation reaction that damages the hair from within.
Metal build-ups have two typical consequences:
-
Color changes: Copper stains especially light hair greenish. Iron, on the other hand, makes hair dull orange or rusty.
-
Weakened structure: Metals make hair stiff, coarse, and difficult to manage. They can also ruin chemical treatments, such as coloring or perms, and lead to patchy results.
Why isn't clarifying shampoo enough?
Clarifying shampoo does remove product residue and build-up, but it is only a temporary fix. The problem does not go away, as the next wash starts the accumulation of build-ups all over again.
In continuous use, clarifying shampoos are often too strong and further dry out hair and scalp. Instead of treating the symptoms, one should focus on the root cause of the problem: water.
The solution is in the water: An effective shower filter
When the problem is in the water, the solution is to purify it. The most effective way is to install a water filter in the shower, which purifies the water just before it hits your hair.
A high-quality sediment filter captures all solid particles larger than 5 microns from the water. It effectively removes, among other things:
-
Rust and iron from old piping
-
Sand and other fine particles
-
Most of the limescale and other minerals
Installing the filter is easy: it is screwed between the shower hose and the shower head without tools. You will notice the difference quickly. After just a few washes, your hair will feel softer and airier, the color will stay bright longer, and styling products will work better. Scalp itching and dryness also ease as the irritating effect of chlorine is removed.
When clean water isn't enough: Boost with nourishing ingredients
Filtration creates the perfect foundation, but you can give your hair and skin even more. Once the water is clean, it's time to restore moisture and add nourishing ingredients directly to your shower routine.
The aroma gel cartridges installed inside the showerhead utilize Korean cosmetic expertise and release nourishing ingredients into the water during washing. They contain four natural ingredients for moisturizing the skin and hair:
-
Aloe vera: Soothes and effectively moisturizes the scalp.
-
Snail serum: Known for its repairing and regenerating properties that help strengthen hair.
-
Milk protein: Smoothes and nourishes the hair's surface, making it soft and shiny.
-
Vegetable glycerin: An effective moisturizer that binds moisture and keeps hair and skin supple.
By combining an effective water filter and a nourishing aroma gel cartridge, you create a routine that not only cleanses but also actively cares for and protects your hair with every wash. It is a comprehensive solution that strikes at the heart of the problem.
Frequently asked questions
How do I know if water is the cause of my hair problems?
If quality hair care products don't help and your hair is constantly dry, coarse, and lifeless, the cause is likely in the water. Rapid color fading, scalp itching, or a greenish tint in light hair are also clear signs. The easiest way to find out is to try a shower filter and feel the difference.
How often should a shower filter be changed?
The replacement interval depends on water quality and consumption, but generally it is 3–8 months. The filter darkens with use, so you can easily see when it's time to change it.
Does a water filter affect water pressure?
A high-quality filter does not reduce water pressure. If your old shower head is clogged with limescale, a new filter-equipped shower head may even improve pressure.
Do the filters fit all showers?
Yes, our filters and shower heads use the common G1/2" standard thread, so they fit almost all Finnish showers. Installation is easy by hand, no tools are needed.
