HairColourChart.online is an interactive companion for hair colouring, built to help you find your perfect shade and dye it confidently at home. At its heart is a professional HSV colour wheel that lets you pick any shade and instantly preview it on hair, together with a layering simulator that shows how a dye will sit over your current colour, and a photo try-on tool so you can brush a tint onto your own picture before committing.
Beyond the wheel, the site offers a curated library of real hair dye shades available in the UK from brands like Garnier, L'Oréal, Schwarzkopf and Bleach London, a complete dyeing guide covering colour theory, methods and aftercare, a plain-English safety page on patch testing and reactions, and a regularly updated blog of colour stories and how-to guides.
It's made for anyone dyeing their hair at home in the UK — from first-timers nervous about their first box dye to experienced colourists who want a quick visual reference. The guidance is researched and kept practical, always reminding you to patch-test and follow the instructions on your specific product.
HairColourChart.online is built by a small, independent team who love hair colour and believe salon-quality knowledge should be accessible to everyone. We're not affiliated with any dye brand; the shades and advice are curated independently to help you make informed choices.
