Hi,
My hair was always a dark brown almost black and now I am completely grey after 3 years of chemo medication. I like the grey but it is very uneven with white mostly at the fringe with dark grey/almost black in sections. I am querying whether it is possible to have dark ash brown streaks through my hair as fully dying it will be pointless as it appears within 3 weeks . I now have no colour in my face and I always used dark ash brown or blue black before I turned grey as any other colours just turned a bad ginger auburn after a while. Hope some one can give me some advice please . Thanks

Sorry to hear about your condition, and congratulation for getting over it. One thing you may already know is that chemo alter your melanin function . The first thing to do is ask your Dr. how long it takes to get rid of all the chemical in your body because they influence the hair color you are going to use .
If you are clean from chemicals I would seek a professional to color my hair. It seems to me that you are dealing with more than 1 color, It would be rather difficult to get a perfect result at home.
Hope This help Good luck and Kind regards.
