5 most common at-home hair dye mistakes and how to fix them
Colourists say box dyes come with lots of risks. But whether your hair came out damaged, too dark, or too orange, colourists have a fix
It’s happened, even to the best of us. You used a store-brand box dye to change your hair colour, and it didn’t quite come out the way you were hoping. Sometimes, at-home box dyes can lead to minor mishaps like a colour that’s slightly too dark or hair that’s feeling brittle. Other times, though, they can cause disaster in the form of hair that’s totally uneven or even straight-up orange.
According to London-based colourist Leanne Chadwick, there’s a reason those at-home hair dyes that come in a box can be so fickle. It mostly comes down to the developer, the part of the dye that opens up the hair follicle so that pigments can penetrate them. “You have one box dye that ‘everyone’ can use and achieve the same colour, therefore, the strength of the developer will need to be strong enough to lift very dark hair, even if someone with really light hair is also using it,” Chadwick explains. In other words, developers can’t be customised to your specific hair colour with a box dye as they can be in a salon. That’s why at-home box dye kits come with far less predictable results and can lead to all sorts of common kerfuffles.
