Essential cookies
Strictly necessary cookies for the site to function. This includes your consent choice (so we don't show the banner every visit) and session/security cookies when you submit a form. These cookies are retained for 12 months and cannot be disabled. We temporarily store your hair-analysis answers (up to 7 days) so you can resume the quiz when you return — these stay only on your device.
Analytics cookies
We use Google Analytics 4, loaded through Google Tag Manager, alongside Cloudflare Web Analytics. Google Analytics measures page views, referral source and conversions. Google Tag Manager loads only after you accept analytics or marketing cookies, and what may then be stored is decided per category by Google Consent Mode v2. Cloudflare Web Analytics does not identify individual visitors.
Marketing cookies
This toggle drives Google's advertising signals (ad_storage, ad_user_data and ad_personalization). If you decline this category, Google may not use your visit to measure or personalise advertising. The Meta Pixel (Facebook and Instagram) no longer falls under this category as of 3 September 2026. That pixel loads on every page and for every visitor, even if you decline marketing cookies; we use it to measure the result of our advertising campaigns. If you would rather it did not, you can block it with an ad blocker or with your browser's tracking protection. You can also request access to your data or its erasure through the email address at the bottom of this page.
Changing your choice
At the bottom of every page you'll find a 'Cookie settings' link that lets you change your preferences at any time. You can also clear your browser history to reset your consent choice — the banner will appear again on your next visit.
