I get my hair cut every two-three months and it costs $40. And for $40 is dirt cheap for getting my hair cut, dyed black, bleached tips/streaks, and then getting the bleached portions colored. All in all it takes about 2.5 hrs from the time I sit down until I walk out.
EDIT: I usually give her $5 or $10 tip so $45-$50 is the total cost.
