The cost of getting a professional hair coloring job at a salon depends on the color and type of dye job and the location of the salon. An Angie's List poll found that consumers across the United States pay about $100 a month on average to keep their hair dyed.
At most salons, brushing in highlights costs less than full color coverage. Dying hair a dark shade also often costs less than going significantly lighter. Covering a lot of gray hair may also affect the final cost. To find a fair price for a given area, call several nearby salons and compare what they charge.
