Blonde hair

[Alicemtaylor2000]

Does anyone have a fail safe product for colouring roots of previously light blonde highlighted hair ? I've never successfully coloured my hair at home before

How dark is your natural colour? I’ve done my roots with a box and they look fine, although my highlighted hair is only a couple of shades lighter than my natural colour.

The only way you are going to be able to do this is with bleach. Do not use a blonde box dye, it will go orange, unless your roots are also quite light!

a hairdresser told that to avoid the orange danger buy some blonde colour with the word 'ash' in it

... as opposed to 'golden' or 'warm'

How did you manage to just do your roots? I’ve got massive root growth, was overdue an appointment at the start of lockdown.
My highlights are bleach and ash. My natural colour is ashy/light brown.
I’m really tempted but I know my hairdresser will kill me.
Can I just do the roots easily?

I used a dye that had a pointy nozzle and sort of did stripes of the dye along my parting and around my hairline, running the dye through my hair to the ends. I changed the parting slightly, about an inch either side of where I normally part the hair and did the same there. When I washed it out, I parted my hair very slightly to one side of my natural parting, and it looks fine. Parted in the origin place it originally looked a bit stripy but this has now settled down.
