Like many on this thread, I started to get a few silver hairs in my teens, and have been dyeing it ever since. However, the colour was never quite right and would lift incredibly quickly, often leaving my hair look brassy. When the pandemic and lockdown happened, I took the opportunity to stop dyeing and grow my hair out - at this point, I was mid 40s. Although parts went the most beautiful shades of white and silver, much remained my natural nondescript brown. Even so, I loved the white and silver, particularly when my hair was pulled off my face. I think lighter hair around the face looks so much more flattering than darker hair as we age.
When I was diagnosed with cancer last summer, and then told I needed chemotherapy, part of the reason I opted not to cold cap was to let my hair fall out in the hope that when it started to regrow, it would be white, or else grey and silver. Yes, really. When I got a wig, I decided to get one in shades of silver and white and it suits me far more than my original hair colour ever did. That said, I rarely wore it. I have now finished chemo and annoyingly amazingly, I have retained about 15% of my original hair, all of which is brown. However, the regrowth is nearly all white which I am incredibly excited about. As horrible and emotionally difficult as losing my hair was, the decision to do so is proving one well made (even though it's going to take around 18-24 months to fully regrow my hair to a decent length).
I love grey hair on women. Growing up, some of the most stylish (older) women I knew did not dye their hair. Sarah Harris (an editor at Vogue) does not look older than her years, nor to many women who go grey. I have found the most pushback to be from those usually older women who still dye their hair in their 60s, 70s and later who are most appalled about younger women going grey, citing it's frumpy and ageing. I really disagree with this. I think many older women with obviously dyed block colour hair look far older. I used to work with a woman in her late 50s who did not dye her hair and it was about 60% grey. I saw her recently in the supermarket and she's succumb to hair dye. It's so harsh against her skin tone, and it makes her look so much older. Tbh, I did not even recognise her at first.
