Terms of Service

These terms cover using greycover.com: the six calculators, the blog, the learn section, and the museum. Using the site means you agree to them.

What GreyCover Is

GreyCover is an independent, ad-supported reference site about grey hair care, root coverage, and color maintenance. It is not a salon, not affiliated with any hair-color brand or cosmetology board, and not a medical provider. The Gray Coverage Calculator, Developer Volume Calculator, Color Mix Ratio Calculator, Going Gray Timeline, Root Touch-Up Scheduler, and Toner Mix Calculator are free, browser-based tools built on common hair-color conventions and the numbers you enter.

Using the Tools

No account, sign-up, or payment is required to use any calculator. Inputs you type into a tool are processed in your browser to produce an estimate; see the Privacy Policyfor what does and doesn’t leave your device. Results are general guidance based on standard color-industry conventions and rules of thumb, not a measurement of your specific hair by a professional colorist.

Not Cosmetology or Medical Advice

Nothing on GreyCover is professional cosmetology, dermatological, or medical advice, and GreyCover is not a salon. Always patch-test a new color or toner product first and follow that product’s own instructions, which take priority over any general estimate on this site. If you have a scalp condition, an allergy, or a complex chemical hair history, talk to a licensed colorist or a doctor before applying color at home. The full reasoning behind this is in the Disclaimer.

Acceptable Use

When using the site, you agree not to:

• Automate requests against the tools at a volume that degrades the site for other visitors
• Scrape, republish, or resell the site’s content or tool logic wholesale
• Attempt to bypass, disrupt, or probe the site’s security
• Submit deliberately false information through the contact or subscribe forms
• Use the site for any unlawful purpose

Content & Ownership

GreyCover’s own text, calculator design, and site design belong to GreyCover. The museum and learn sections draw their entries, images, and facts from Wikipedia and Wikimedia Commons, used under their respective public-domain and Creative Commons licenses — that content belongs to its original contributors, not to GreyCover.

Ads & Affiliate Links

The site carries Google AdSense advertising and, on some tool and article pages, Amazon affiliate links. Both are disclosed in full in the Affiliate Disclosure. Ads and product links are served by third parties and are not endorsements by GreyCover.

No Warranty

The site, its tools, and its content are provided “as is,” without warranties of any kind, express or implied, including accuracy, fitness for a particular purpose, or uninterrupted availability. We try to keep the calculators correct and the guides current, but we don’t guarantee either.

Limitation of Liability

To the extent permitted by law, GreyCover isn’t liable for damages arising from your use of, or inability to use, the site or its tools, including a color result made at home based on a calculator result or an article.

Changes to These Terms

These Terms may be updated from time to time; the date above reflects the most recent revision. Continuing to use the site after a change means you accept the updated Terms.

Governing Law

These Terms are governed by the laws of the United States, without regard to conflict-of-laws principles.
