HI ladies
I was distressed about my hair also. After much testing, research and chatting to others, my hairdresser used foils so that the colour never actually touched my scalp. She put heaps and heaps of really fine ones in and the hair dye was encapsulated within the foil package. She used three different colours to cover/enhance the grey - light blonde, gold and caramel. (I was naturally 'dirty blonde' before I began messing with it!)
It looked SOOO good that I now have the same treatment all the time. I don't get that straight line of contrast when it grows out - and around the ears that is a very good thing. My hair is almost white there.
Each treatment she concentrates most foils on a different area, eg around the sides, around the crown, at the nape. It has been the best transition from permanently dyed hair to (in time) natural looking aging. People tell me how 'well' I look - so it must be working! :)
Good luck with the new look!
