So since the birth of dd I have accumulated a few grey hairs. They are on the sides of my head underneath the top layer of hair. I have to wear my hair up a lot for work and because dd pulls it. It really bothers me that you can see them. I want to dye my hair, professionally (tried home dye but I missed 90% of them!). It needs to be inexpensive to top up and low maintenance, I'm only 31 and I have dark brown hair. I'm toying with the idea of highlights or maybe just a semi permanent colour. Help!
