Quick question re. hair dye

[MrsJBaptiste]

Can I use leftover hair dye from when I did my roots 6 weeks ago?

I'm sick of using the coloured hair spray and have found some old dye I'd kept from last time I coloured it. So would you/can you use it?

Do you mean mixed or is it still in the tube/half tube and the developer bottle ?

If mixed them they advice to dispose after use

Yeah, it is mixed so probably shouldn't risk it. Damn!
