Grey hair

[Sexentric]

I am 46. I used to have very dark (almost black) hair but started to go grey very young. Noticing strands in my teens. Obviously as I got older there were more and I started dyeing ut when I was probably early 20s. As time went on my roots got more and more obvious so I had to dye it every 3 weeks or so which was a nightmare. So I gave up in lockdown. I've been grown out salt and pepper for a few years now but I dont think I like it!
I do think it makes me look older - at least from the back. I think im pretty lucky with my skin and I dress reasonably fashionably which helps. A lot of my colleagues are MUCH younger and I have had a couple of them seem to be genuinely shocked when I've told them my age. Saying that I 'rock'grey hair and they thought I was younger. I do think though that's less because of me looking young and more them sort of thinking their colleagues are roughly their age.
So my questions are:
Do you think grey hair gives an 'old lady vibe'
And also is there a way I could colour it to make me look younger or even 'warmer'as I used to.be an autumn colouring, without having to retouch every 3 weeks or so. I just can't handle that sort of commitment or cost.
And if you got that far then thank you!

I use pure henna (that’s the brand) to go dark brown. It works really well. I use ‘natural brown’.

I think it’s brave to go grey, especially in your 40s.

I am 53 and I’m just too bloody vain to consider letting the greys take over. My hair is long and curly, and I suspect that would look frightful. So cut my thick, curly hair short? With the grey - instant granny perm.

A couple of friends that are very grey have recently ditched the dye. It doesn’t look good on either of them tbh. One has kept her ‘old’ hairstyle - a very blunt bob with a thick fringe. The grey makes it all quite helmetty. The other has short, choppy hair so it does look good but she’s extremely pale so the 2 together wash her out.
