Frequently asked questions
Quick answers before you shop.How do I use a The Hair Diagram promo code?
Pick a code on this page and select "Show code". We copy it for you and open thehairdiagram.com in a new tab. Add what you want to your basket, then paste the code into the promo or discount box at checkout and apply it before you pay.
Are these The Hair Diagram codes checked?
Yes. Every offer on this page comes from The Hair Diagram's own affiliate feed and is read by a person before it is published — we check the wording, the conditions and the end date. We never scrape codes from other coupon sites.
What happens when a code expires?
It is hidden from this list on its end date, shown for 21 days in a clearly labelled "recently expired" block, and then removed from the site entirely. We do not leave dead codes at the top of the page.
Why did a The Hair Diagram code not work?
Most codes carry conditions — a minimum spend, selected lines only, new customers only, or one use per account. The conditions we have are printed on each card under "See Details". If a code still fails, tell us on the contact page and we will re-check it.
Does PriceThrift get paid for this?
We may earn a commission if you buy after using a link or code here. It costs you nothing extra and it does not decide which offers we list or how we order them.
