Growing out grey, how to make it a bit less painful?!

[Kracken]

I'm taking lockdown as an opportunity to grow out my grey hair and go natural. At the moment I have about 1.5 inches of greyish brown roots (at least 50% grey I reckon) then the rest, to just below jaw length, is a reddish brown base with a mix of various shades of blonde highlights. It looks terrible as you can imagine! My hair is also curly so it's pretty dry, made worse by the blonde highlights.

I am hoping there is something I can use like a semi permanent glaze or gloss that will tone down the brassiness and red/orange shades and bring it all together somehow, whilst also conditioning it a bit. I considered Living Proof Whipped Glaze Light. Before I spend a small fortune on products that may or may not work (and might make my hair look worse, although I'm not sure how that's possible!) I was hoping the wise folk of style and beauty might be able to help! Thanks so much.

I have grey sprinkles and I only ever use a semi permanent colour...to avoid that mono colour and roots showing as a line
This is the one I use. I have dark hair and avoid any with a red undertone as over time that redness seems to be more prominent. Even though I’m dark I tend to use a light ash brown type of colour and it blends it in. After a few uses I only put it on the top half (I have very long hair) as it gets darker ends otherwise

That’s not the colour...just the first one of that brand I found!

Use an ashy semi perm brown with a purple shampoo. Deep condition it regularly (at least twice a week).

When I grew mine out I got it dyed a similar colour to what was coming through which helped make it not quite as traumatic. Pulling the top but back also helped disguise the roots a bit. If you dyed bits have gone brassy you could try using purple shampoo?
