Yes, mine did start coming back with loads more grey than colour. As it got longer the colour did come and now the grey is back to where it usually is and not such a lot of it. My first lot of hair was curly and like steel wool so it got a cut pretty quick. The next lot is wavy so I am growing that a bit longer. Looks a bit unruly but hey its winter time coming and I like some on my neck and around the ears so I am leaving it for now. The front isn't growing and I suspect there might be a bit of baldness going on there. A fair bit still falls out (maybe due to Tamoxifen) but for joy, its only the grey ones. :)
