This reminds me. I know a woman who I met 10 years ago - a neighbour in the next street from me. When I met her she looked about 45 and her husband looked about 54. (Lyn and Lee.) Lyn had dark brown hair and Lee's was salt and pepper grey. Anyway, she always had dark brown hair when I saw her and she has dark brown eyes and so the dark hair suited her.
Anyway, fast-forward to 4 years ago when I had known her 6 years and I didn't see her for about half a year as she moved 3 miles away... Suddenly Spring 2020, I saw her and her hair was 100% grey ... silver grey. It had aged her 15-17 years! I was absolutely stunned. She went from looking 45 last time I saw her to looking 62, all in the space of 6 months. Turns out her true age was 5 years older than I thought. So when I met her she was 50 and looked 45. With the grey hair she was 56 and looked 62.
So I think this is what the poster meant who said grey makes you look 20 years older. I think that is untrue. BUT if someone (aged say 44,) goes from dark brown/blonde/mousy to grey, they can go from looking 39 to looking 52-55. So whilst 20 years older is a bit of an exaggeration, suddenly going grey after many years of being blonde/brown haired/dying your hair can easily make you look 15 or more years older.
Lyn's husband who looked about 54 - was actually 46 when I first met him, so HE looked older too. Even so, men definitely carry grey hair (under the age of 60) better than women do IMO. Call me what you like. I am entitled to my opinion!
Conversely, there used to be a woman who worked at our GP surgery who looked around 52. She had hair that was 40% medium brown-ish and 60% silver grey.
Suddenly 2 years after I first met her, she dyed the grey and was all medium brown, and she looked 15 years younger. Turns out she was 39! Looked more like 39 with the grey dyed out. Early to mid 50s with it!
I agree with some posters on here, that the poster with the grey bob who popped her photo on here (at 12.53 on 29/01/24, and said she is 57,) looks OK, and the hair looks OK, but she does NOT look 37! I would say early 50s at the youngest. Why do people come out with this ALL the time when someone posts their photo on here? 'OMG babe U look amazing! You look TWENTY YEARS younger even with grey hair.' Come off it. She looks fine, but she doesn't look 20 years younger. No-one does FFS! And most definitely not with grey hair. Get real! 😆
