Hi Carmel,
I've had the same response to my very white hair. I too went silver grey very early - late 20's and have been dying it ever since until my BC journey began last year. I too have had so many positive comments about how nice it looks the way it is now. I think I'm just going to leave it a while, too. I'm quite content with how I look. Also dying it is expensive.
Good luck with your new look and the months ahead. Have you finished all treatment? I'm still having 3 weekly herceptin until October and of course Tamoxifen daily for the next 18months then Femara.
Take care,
Alison xx
