Wash in wash out problem

[LydiaIHughes]

Hi guys,
About a month ago I used a new product 'L'Oréal colorista' in the shade purple, this is supposed be a wash in wash out hair dye, and after about 3 washes I noticed some blues in my hair too, I didn't think too much of it as I know sometimes these types of products can take longer to wash out, especially as my hair has been bleached a lot, particularly at the ends. However it's been over a month since I've done this and my hair now has a green tinge at the ends.. slightly concerned that it's now permenant. I have a wedding this weekend and just want my blonde hair back! Any help/ suggestions would be really appreciated, thanks in advance x

It's common for direct dyes to stain the cuticle layer if the hair has been previously bleached. You either need to cover it with colour or cut it out.
