About Hello Klean
Hello Klean is an independent beauty brand whose range is built around hard water. Launched in 2019, it set out to make shower products that deal with the mineral content of tap water and the skin and hair complaints that come with it. The line covers shower filters and filtered shower heads alongside shampoos, conditioners and body washes, all designed to limit mineral buildup and ease irritation, and the brand also puts out guidance so shoppers can find out what is in their local water and what it means for them.
Orders are placed through the Hello Klean website, which takes Visa, Mastercard, Amex, PayPal, Google Pay, Apple Pay and Shop Pay.
Standard orders over £35 ship free, and anyone signed up to automatic filter replacements gets free delivery on each recurring delivery. Items can be sent back for 100 days provided they are in satisfactory condition, and an exchange is possible within that same window.
There are several ways to save. Full-time students over the age of 15 who are eligible can take 10% off, verified through partner platforms, and NHS staff and key workers can claim a discount arranged through networks such as NHS Discounts. New customers who register get 15% off their first order, and a referral link passed to a friend gives first-time buyers 15% off at checkout. Hello Klean shares updates on Instagram, TikTok and LinkedIn.
