@Michele82 neither of my parents went grey until they were about 55, so I've high hopes! That being said, I've noticed people age earlier in the UK than in other countries - back in Canada none of my friends my age (30-40) have grey hairs yet!
@Areej my mum said the same thing to me. When I had a few I just used to pluck them out. Now I have a few more, about 15 ish I dye my hair. In between getting it coloured I use root touch up and I've picked up a L'oreal hair mascara which hides the little ones near my temples for the day. It's going to a long and hard battle keeping the greys at bay until I give up the fight and just go all white!!!!
I always pull mine out. I try to tell myself the old wives tale is true so I wont do it but I do it anyway!Usually they grow at the sides and are quite concealed but every now and again one crops right out of the top and its quickly pulled out, sparkly be gone!
