Just that.
I am mid 60s (but taken for being much younger- sorry but and looking younger runs in the family. Adult DD gets IDd all the time.)
Anyway- I've always had some subtle highlights in my dark blonde hair, and now that I've gone a shade deeper with them for more 'warmth' I'm a bit shocked at how much grey I have ( the grey always looked more like light blonde.)
Hairdresser says I am 50% grey.
