GarnierOlia permanent colouring and bleaching 4.0 Castano Scuro

...this particular seller apparently ships from Bulgaria. I didn't realise this until the order took way longer to arrive than normal. Now, it's still a great hair dye and this shade is tricky to find at the moment. But there are no instructions in English, so we weren't able to figure out how to do the allergy test. Hopefully my son won't have a reaction this time 😬 So basically, if you speak fluent Bulgarian you'll be fine, otherwise you might want to consider using a UK seller.
