A shampoo to turn white hair grey

[Thertza]

I thought I'd found the holy grail with Bleach London Fade to Grey, and whilst it's absolutely the best of found I do now have violet streaks which I'm not fond of.

Has anyone found a shampoo that turns white hair grey without adding purple / violet?

There’s a grey conditioning mask that I’ve used on salt and pepper hair that doesn’t seem to go purple. The effect lasts for a few washes. www.amazon.co.uk/Osmo-Colour-Revive-Steel-Conditioning/dp/B08BG5DH8M/ref=asc_df_B08BG5DH8M?mcid=044ba7492c8e39c9bbcbd7213d528074&tag=googshopuk-21&linkCode=df0&hvadid=696385525345&hvpos=&hvnetw=g&hvrand=13494298340261556058&hvpone=&hvptwo=&hvqmt=&hvdev=t&hvdvcmdl=&hvlocint=&hvlocphy=9046491&hvtargid=pla-945761111018&psc=1&gad_source=1

Charles Worthington Colourplex grey shampoo and conditioner did this for me (actually it’s not what I wanted) so might be worth a try.
