Well depending on how much this jobs means to you, you can get it done by a professional but it will cost much more than doing it yourself, say anywhere between $50 to $100 or so. If you want to do it yourself, they make a ton of hair colors and it won't be that hard to match it. Go to a beauty supply store and have the employees help you. Bleaching it will probably turn it nearly white then you color it back using the color suggestion from the employees. Although it will be starting off lighter than what the employees at the beauty supply store will have seen, it should soak up that color and become a near match. If you have to you can dye it again or try it yourself then if you fail get it professionally done.
If you have stopped smoking and it has been 14 days or more since your last smoke, it won't matter when you do the treatments. The body stops depositing THC metabolites in the hair shortly after the last time you smoke (2-3 days). Then you have lag time for the hair has to move out of the follicle and far enough out of the scalp for it to be cut. This usually takes 10 days for both processes but I'm going with 14 to be safe. If you successfully clean the hair 14 days after last smoke, no more will be deposited and it won't get "dirty" again. If you are using the Macujo method in addition to bleaching then you want to space things out as so not to burn your scalp. The mac method can be found by doing a advanced search for post by me in the drug testing section using the term laundry.
