@polka6 glad it helped.
The red tinge on black hair sounds lovely!
I think the lighter red strands sound lovely too, but sounds like that's not what you're after.
For grey hair my view is, if the aim is to disguise the greys, ( & btw I think salt & pepper can look great) the long term reality is that gets harder the darker the base is. Because that increases the contrast with the lighter hair & you'll always be fighting more obvious regrowth at the roots .
So main permanent options if reducing visibility of the grey is what you're aiming for:
- Lighten the base to reduce the contrast. But this can be a lot of maintenance & has to end up quite a bit lighter than black hair to really be effective.
- Introduce highlights so theres a few more different colours in your hair, this blends the greys a bit more so they "read" as maybe part of the highlight effect among a range of colours. But it's definitely more of a blend than a complete coverage effect. You could try e.g. red/ auburn/ toffee/ caramel/ gold...
I'd suggest a lot of looking at images (preferably real-life not just hair models, so facebook groups, instagram etc.) & have a proper in-person consultation with a professional who specializes in colour. They need to assess your hair condition root to tip, assess your grey % and its pattern.
Or you could try a semi- permanent in dark brown, over time you might be able shift the look of the greys to chocolatey highlights. And using semi-perm means the developer strength is gentler - which I've alread been on a soapbox about in this thread!
Shampoo & conditioner - Beauty & Planet colour safe are good.
Enhancing natural curls can often be achieved by bond building - so I'm going to suggest Olaplex or Pureplex Hair Repair (much cheaper & very nearly as good, at Boots & Superdrug) kit as I've seen people get more defined waves & curls from that. I'm not on commission, but I should be!
They also do a shampoo & conditioner, but I haven't seen evidence those are anything amazing.
Good luck with all this !
