I have naturally dirty blonde hair which has the occasional red and brown hairs running though it. Over the past year or two (I’m mid 40s) I’ve noticed more colourless hairs, for want of a better description, which I’m assuming are my grey hairs. I’m the only one in my family with blonde hair so I’ve no idea what it’s going to look like when I go fully ‘grey’. Any natural blondes out there who have gone grey - if so what type of grey, do you colour it or tone it now.
