Ash hair has a green tinge and looks unflattering

[daisystone]

Right, so I have often dyed my hair in the past and generally it has come out well. When I am dying it blonde (my hair is naturally browny red) I have to pre-dye it first to get it to a light colour and then I use a box colour over the top - I like Clairol, it often comes out well.

I decided that ash blonde would look good but used a different brand this time (wella koleston perfect special ash blonde) after pre-lightening my hair. My hair is now ash but it does not look good on me and it also has a greeny tone to it. I do not want to keep it and I have a Clairol box in Baby Blonde that I would like to change it to.

The question is, how do I do this? Should I put the baby blonde pack straight over my hair as it is? Or should I use a bleach/developer mixture on my hair to lighten it again (in a sense, starting again completely). I have two developers in the house, a 10 volume and a 20 volume, which would be best as my hair is already very light?

Any hairdressers or seasoned dyers that could help? I start a new job next week and do not want to go in looking awful.

First of all it wouldn't put any more bleach on so soon after lightening it - really bad for condition & structure of hair.

In theory you could try going over it with baby blonde, but i would only use a 10 vol (or a 6 if you have it) and would only leave it on for 10-15 mins. But tbh if you have a noticeable amount of green hue, it won't be enough of a neutralising colour to cover it. You need to go for more of a strawberry blonde of honey blonde for it to really work (and as before, only leave f&f 10-15 mins max).

An emergency but good method is to give your hair a tomato ketchup hair mask (honestly!). Leave on for about five mins, rinse really well then condition. Sounds mad but it works.

I don't want to be a honey or strawberry blonde.

My hair is greeny grey at the moment - not loads of green, just a bit of a tinge. Should I not strip the colour and start again then? I realise that could seriously affect the condition of it, but disregarding this aspect, would it work if i stripped it and then re-dyed it?

If it's gone too ashy you need to put more golden/red pigment in it and it'll even itself out. Do you have a proper beauty supply near you? Get yourself a beigey toner, like a 9.2 or 10.2 mix with 1.5% or 3% peroxide and put it on wet. You can see the colour developing on your hair and take it off when it looks right. I second a ketchup mask! Really works.

It won't make your hair honey or strawberry blonde - it's just that the red will neutralise the ash - the reason you don't leave it on for long is that you're not going over it with a new colour, just toning down what you have.

And yes meant to say, yes you could strip the colour and start again but your hair will probably be in pretty bad condition as a result.

Yes to the ketchup.
