Is there a way to colour individual grey hairs?

[BangFlash]

I'd say my hair is about 5% grey at the temples then I have a few annoying grey hairs around my parting.

I occasionally use a light shade of semi permanent or a colour conditioner to tone them in a bit but it gradually lightens and reddens my hair, I would really like to just be able to target the grey.

Is there anything like a mascara I could use to target singlehairs?

Could try the root touch up dyes, they come with a tiny wee brush.

I use the touch up dyes, and the very odd time I used a tiny painting brush.

There are hair dye sticks and 'hair mascaras' that you can buy to touch up with a temporary colour.

Loreal do a magic retouch which is like a mascara. It does cover them but it kind of flakes off and your hair doesn't feel soft when it's on so only works if it's going to be in an updo really.

What colour is your hair op?
