Hi Tracey my hair grew back silver grey and really curly. I have always had dead straight hair so it was a huge shock when it grew back curly. It has now settled and nearly back to what it was like before, if anything it is thicker and I keep it really short. The first time I coloured my hair I went blond didn't like it so have gone back to a reddish purple colour. I didn't do anything special I just let it grow, it was strange at first as I got quite used to not having any hair. My eyebrows are thinner and so are my eyelashes. Good luck because I think it can be a bit of a lucky dip.
