I know what you mean, I've noticed a few greys coming through and they are definitely a lot courser in texture than my brunette locks, so I'll be watching with interest to see what advice (if any) can be offered. Luckily, there are only a few greys at the moment, so they aren't really noticeable, but I think it will get to the stage where I have no option but to colour them. Some women's hair looks amazing with their natural grey colouring, but I've got a feeling mine would just turn into a wiry mess, lol!
