What’s your biggest concern?
Dry, Itchy Skin
"My skin was so incredibly itchy I couldn't fall asleep - every time I got comfortable, another itch I couldn't ignore. It felt like sandpaper and soaked up lotion instantly. Since using Klynein, the itching stopped completely and my skin actually stays soft without that tight, screaming feeling."

"The worst part wasn't just the dryness - it was that waxy, soap-scum feeling coating my skin no matter how much I scrubbed. Ashey patches everywhere, and lotion disappeared instantly like water on concrete. Three weeks with Klynein and that chalky film is gone. My skin actually absorbs moisture now!"
Mary K.
Mary K.
"I was prescribed steroid creams for my chronic dry patches, but the derm warned that chlorine would keep irritating my compromised skin barrier. Klynein let the medications actually work - I need way less cream now and the itching cycles finally stopped. My prescription is lasting twice as long!"

Hair Loss & Thinning
Scalp Sensitivity, and Irritation
"My scalp was driving me insane - constantly itching until it bled, flaking everywhere like a snowstorm. It felt like ants crawling under my hair, waking me up at night. Klynein's gentle water gave me instant cooling relief. The flakes disappeared and I finally stopped scratching myself raw."
Ashley D.

"My scalp was so sensitive, even my ponytail holder was basically torture equipment. The slightest touch sent shooting pains through my head, and washing my hair felt like punishment. Klynein's gentle water was a game-changer. Now I can wear my hair down without feeling like I'm being attacked!"

Sensitive Skin
"My eczema flare-ups were horrible - red, raw patches that actually swollen and flaking with dried skin. It was so itchy it felt insane, burning to the touch after every shower. Klynein's gentle filtered water stopped the flares completely. My skin barrier finally healed and stays calm now."
Kayla P.

"My face would flush bright red every time I showered, staying that way for hours. Even lukewarm water made my cheeks burn and sting. I looked like I had a permanent sunburn and felt so self-conscious at work. Klynein eliminated the redness completely. Finally have normal-looking skin again!"

Loss of Skin Elasticity
"I was already using tretinoin for my crepey neck skin, but progress was so slow. My dermatologist suggested adding filtered water to boost results. Combining Klynein with my retinoid routine accelerated everything - my skin barrier healed faster and the firmness improvement doubled. Perfect skincare partnership!"
Patricia R.
Patricia R.
"My dermatologist had me on peptide serums for fine lines, but she mentioned chlorine was undermining my expensive treatments. Added Klynein to protect my investment - the peptides actually started working! My skin plumped up beautifully. Now my $200 serums aren't getting stripped away immediately."

Frequently asked questions
Does Klynein 5.0 Work For Everyone?
Absolutely! It doesn't matter your age, skin type, hair texture, or water quality issues. Klynein 5.0 has helped people dealing with dry skin, eczema, hair thinning, scalp sensitivity, and general water quality concerns. From college students in dorms to seniors in retirement communities, our 15-stage filtration system works universally. Plus, Klynein comes with a 60-day money-back guarantee, no questions asked. You risk absolutely nothing by upgrading your shower today.
Will This Actually Improve My Water Pressure Or Make It Worse?
It INCREASES pressure! This confused us at first too - how can adding a filter boost pressure? Our engineering team designed precision nozzles that create a more focused, powerful spray while the filter removes pressure-killing buildup from your pipes. Customers with low pressure are often shocked at the difference. If you have a tankless water heater that shuts off with low flow, this actually helps maintain the minimum pressure needed.
Will This Help With My Specific Skin/Hair Problems?
For Dry, Itchy Skin: Removes chlorine that strips natural oils, reducing the need for heavy moisturizers For Eczema/Sensitive Skin: Eliminates harsh chemicals and bacteria that trigger flare-ups For Hair Loss/Thinning: Filters metals and chemicals that damage follicles and scalp health For Brittle Hair: Softens water to reduce breakage and improve manageability For Scalp Issues: Balances pH and removes irritants causing dandruff and sensitivity Clinical studies show 94% of users see skin improvement within 2 weeks, and 87% notice hair improvements within 30 days.
What Contaminants Does It Actually Remove?
Klynein 5.0 filters out 300+ contaminants including: 99.9% of chlorine (the #1 cause of dry skin and hair damage) Heavy metals like lead, mercury, cadmium, arsenic, chromium PFAS ("forever chemicals") Microplastics and pharmaceutical residues Bacteria, fungus, and algae Rust and sediment from old pipes Fluoride (reduces 85% through our multi-stage process) Our filtration exceeds NSF-177 standards and has been third-party tested by independent laboratories.
Why Are The Vitamins Important?
Each shower infuses your water with vitamins A, C, and E that actively nourish your skin barrier. Vitamin C neutralizes remaining chlorine and supports collagen production. Vitamin E provides antioxidant protection against environmental damage. Vitamin A helps with cell turnover and healing. It's like having a skincare treatment built into every shower.
I Have Really Hard Well Water - Will This Last More Than A Month?
Hard water is tough on any filter, but Klynein 5.0 is built for it. Our 15-stage system includes specific media for mineral removal. Expect 4-6 months instead of 8 with hard water. Many customers with iron-heavy well water say it's the first filter that actually works long-term. You can also rinse the filter occasionally to extend life (instructions included).
Does It Remove Chlorine, Microplastics, And Other Specific Contaminants?
Yes! Klynein 5.0 removes 99.9% of chlorine (the biggest culprit behind dry skin and damaged hair), microplastics that are increasingly found in water supplies, and 300+ other contaminants including heavy metals, PFAS "forever chemicals," pharmaceutical residues, bacteria, rust, and sediment. Our multi-stage filtration system targets different contaminant categories - some stages grab chlorine instantly, others trap microscopic particles, and specialized media removes dissolved metals and chemicals.
Does It Remove Fluoride? I Don't See It On Your List.
Yes! Our calcium sulfite and activated carbon stages remove approximately 85% of fluoride. It's not in our main marketing because it's a controversial topic, but it definitely filters fluoride along with the 300+ other contaminants.
Can I Use My Regular Shampoo And Skincare Products?
Absolutely! In fact, your products will work BETTER with filtered water. Clean water helps soaps lather properly, lets conditioners penetrate hair shafts, and allows moisturizers to absorb instead of sitting on chlorine-damaged skin. Many customers find they need less product and see better results from their existing routine.
Will This Work With My Existing Shower Setup?
Yes! Klynein 5.0 fits all standard shower arms and installs in under 3 minutes - no tools required. Simply unscrew your old showerhead by hand and twist on Klynein. It works with both fixed and handheld shower setups (though we're currently developing a dedicated handheld version based on customer demand). If you have an unusual connection, our customer support team will help you find a solution.
How Often Do I Really Need To Change The Filter And What Does It Cost?
Here's the honest truth: Filter life depends on your water quality. Most people get 6-8 months, but if you have really hard water or high chlorine (like Florida or Nevada), you might need to change it every 4-5 months. You'll know it's time when water pressure drops or you smell chlorine again. Replacement filters are €29.95 each. Yes, it's an ongoing cost, but compare that to what you spend on skincare products that don't work!
How Do I Know When To Change The Filter? Is There An Indicator?
No electronic indicator needed - your senses tell you everything. When it's time to change: water pressure drops, you start smelling chlorine again, or your skin/hair feels different. Most people develop a feel for their filter's timeline after the first replacement.
What's Included In The Box And How Do I Install It?
What's Included: Klynein 5.0 Plus showerhead with pre-installed filter 1 backup replacement filter (6-8 months of total filtration) Installation guide 60-day money-back guarantee Installation: Simply unscrew your current showerhead by hand, then twist on Klynein 5.0. If it's tight, use a cloth for grip. The whole process takes under 3 minutes - no plumber needed.
Do I Need This If I Already Have A Whole-House Water Filter?
Yes! Even with whole-house systems, shower water still contains chlorine (added after filtration), plus contaminants picked up from pipes between your filter and showerhead. Klynein provides that final crucial filtration step. Many customers with whole-house systems still report dramatic improvements in skin and hair after adding Klynein.
I'm In An Apartment - Can I Install This Without Getting In Trouble?
Perfect for apartments! It's just unscrewing one head and screwing on another - no permanent changes. Takes 2 minutes and completely reversible when you move out. Save your original head to reinstall when you leave.
