About Hello Klean

Chlorine, metals and mineral build-up can affect how hair and skin look and feel from the very first rinse. Hello Klean combines advanced shower filtration with targeted hair and body care designed to improve the quality of your water and the performance of your routine.

Hello Klean is a hard water beauty brand that develops water filtration, hair and body care that reduces the effects of chlorine, hard water minerals and metals on hair and skin.

Today, Hello Klean is available across the UK, Europe, Canada and the GCC through leading retailers and at helloklean.com.

Beauty starts with water

Before your shampoo, cleanser or serum gets to work, your hair and skin meet water.

In many homes, that water contains chlorine, hard water minerals and trace metals that can affect how your routine performs.

That's where Hello Klean begins.

We traced it back to the water

Hello Klean began with a simple question: why did the same routine deliver completely different results depending on where you were?

After years working in beauty and travelling frequently, co-founder Karlee Zhang noticed her hair and skin changed from city to city—drier in one place, dull and tangly in another, irritated somewhere else. Same routine, same products, different results.

The variable was the water. Hard in one city, softer in the next, chlorinated everywhere. Once she saw it, she couldn't unsee it.

Existing shower filters were built for plumbing. We wanted to build one for hair, skin and everyday routines.

So in 2019, Karlee and co-founder Omer Ozener invested £60,000 of their own savings to begin developing Hello Klean—testing early prototypes in their own bathroom before bringing them to customers.

"Water is the first thing your hair and skin come into contact with every day. We believed it deserved the same attention as the products that follow."
— Karlee Zhang, Co-founder

Where we are now

Today, Hello Klean is one of the world's leading hard water beauty brands, trusted by more than 500,000 customers and available through retailers including Sephora UK, Ounass, and Selfridges.

We remain independently led and continue to invest in better filtration technology, product testing, and education around water quality.

The story so far

A short timeline of how a bathroom experiment became a category.

  • 2019 — Founded by Karlee Zhang and Omer Ozener, bootstrapped with £60,000 of their own savings. Launched the first Hello Klean Shower Filter.
  • 2023 — Launched in Selfridges, and introduced hard water beauty to millions through Dragons' Den. Launched the first Hello Klean Shower Head.
  • 2024 — Launched in Sephora UK; named to the FEBE Growth 100
  • 2025 — Hello Klean expanded beyond filtration with wash-off products formulated to defend against the effects of hard water.

BRITA Group took a strategic minority stake in Hello Klean, its first-ever investment in beauty; we passed 1.2 million products shipped and remain independent and founder-led

Built around your water

Every product we create starts with the same belief: better water helps your routine perform at its best.

Our independently SGS-tested shower filters reduce chlorine and help reduce heavy metals before they reach your hair and skin, with independently tested filtration at the source. From there, our hair and body care is formulated with Klean Complex™ to help defend against the effects of hard water, chlorine and mineral build-up.

Together, they work as one routine—improving the water first, then supporting your hair and skin with targeted formulas.

Start at the source

Better hair and skin doesn't begin with another product. It begins with the water you use every day.
