Your hairdresser was honest. Pity that Dawson's isn't!! It's the same where I live regarding the dyed black hair. Maybe when they were young, their hair was dark, but trying to keep it that colour doesn't look right because their complexion has changed over time. Often, the same ladies will use too much blusher and bright red lipstick. Softer is always better after 'a certain age.'We say, you know, here in N.I. But the only time I notice it is if someone is being stopped in the street to be interviewed by the local news. Then it is you know, you know etc.
A thing here with women in their 60s plus is this habit of dying their hair black! Oh, and then the white roots grow out, so you have like an inch of white at the roots. The black dye washes them for a start, and they would look so much better with the white hair.
I am a natural blond, of course it darkened to a dark natural blond. For some reason at both sides of my head at the front I had two strips which stayed the light blond. I do dye my hair and just use a natural blond shade, I even had people surprised I colour my hair. So I must be using the right shade. I remember once saying to my hairdresser I fancied going red. She said no, I would not suit it.
You could try. It will save you time and expense.I started to go grey just before I left school age 28.
I’m 68 now and have it coloured every 6 weeks but I will probably go ‘au naturel’ by 70.
