"The biggest trick I've learned is to choose a style and color that is compatible with your time, lifestyle and budget. Some hair looks are so incredible, but the reality is that sometimes the time, cost and lifestyle required to maintain is not realistic. To determine what will work for your specific needs, ask your stylist and colorist three key questions: How long will this look take to style daily or weekly? How often will I need to maintained my look in salon? How much can I expect to pay each visit?"
