Best hair dyes for resistant grey

I would also like to know - thanks ..

I 've been colouring my own during the pandemic and I find Nutrisse is the best for covering some quite coarse grey hairs I always used Nice n Easy before but it wasn't covering even when left on for a longer time

Now that socializing is limited it might be an opportunity to let the dye grow out and embrace the grey?

I agree with CocoPops. Go for it, GOTG.

I use L'oreal Excellence , works for me. I always do a patch test first, I think that's quite important even if you have been using the product for a while.

Excellence is an excellent hair dye Ann1954

I stopped colouring my hair some years ago - but I had the opposite problem. My hair is extra porous, so light brown would turn out dark and dark brown would end up black. Not a problem 30 years ago, but I’m happy to be grey now.

I too embrace the grey......well more white actually....

My advice would be to not use a box dye. Go to Sally’s and dependant on your colour buy a bottle of peroxide - the 10 volume if you want to maintain a colour, 20 volume for a lift (maybe 2/3 shades lighter than your roots).
Mix that with a toner 1 which is a tube of colour in a bowl, consistency should be like custard (1/2 a tube for shoulder length hair).

Apply to coloured ends first for 15/25 minutes then the virgin roots for a further 15/20 minutes.

Wash off with shampoo and double condition.
Your colour will last longer than a box dye.

It’s more expensive initially, but you should get 2/3 applications from your toner and the peroxide lasts for around 5/6 overall applications in my experience.

I’ve not coloured mine for just over a year now. Been colouring it for nearly 60 years. I’m loving the grey and wished I’d done it years ago. I’m saving hundreds of pounds a year and my hair is in better condition than ever.
