We suggest that if a salon is charging on average $45 for a half hour haircut, then they might charge $100 per hour for the straightening service. The entire process will take anywhere from 3 to 6 hours. A complete client consultation is recommended, prior to scheduling the service. This will help determine the time the process will take, and will also give the client an idea of the cost involved.
