Do I need to bleach again?

When was the last time you bleached?

I bleached two weeks ago with 20vol, I plan on leaving my hair another 2-3 weeks though to recover.

Just wondered if I actually need another bleach or if I could start toning.

I would start using bleach baths, if your hair is healthy, in another 2-3 weeks then. You could give your hair some TLC in the meantime - coconut oil, protein reconstructor, that kind of thing (there are plenty of threads on here about them 🙂 ) and then bleach bathe once a week (again if your hair is healthy enough) until your hair is a little paler. I'd probably say that you'd only need to bleach bathe twice, maybe? And then I think washing with a silver shampoo would achieve what you're looking for.

(A bleach bath is mixing bleach with shampoo; there is a thread on it somewhere here in the bleaching section.)

Some strands look very pale already, i would avoid bleaching those again. i think you will have to go through and spot bleach the darker areas to try and even things up.
Try toning in the meantime, it will help to show which parts need to be lightened further, as some parts will already go to a light ashy blonde with a violet toner. It will help the darker bits to look less brassy too

Thanks for your replies! I put coconut oil on overnight (still not washed it out yet...is there a maximum time I can leave it on?) and I have some k-pak coming through the post.

I will start toning then...should I just use silver shampoo or buy a specific toner? Also probably a stupid question about the shampoo, do I just use the usual amount I use for washing my hair or do I cover my hair with it?

Thanks again

For toning you need to coat your hair in the shampoo and leave for a while to take. I prefer to make my own toner with violet dye diluted in conditioner. Much kinder to hair than leaving shampoo on and you can control how strong you make it.
