You've likely heard that beauty schools offer free or seriously discounted haircuts by students under teacher supervision. At Aveda Institutes, for instance, you can get $15 to $25 cuts (AvedaInstitutes.com). You might also try massage schools: The American Massage Therapy Association lists institutions on its site, searchable by state (AmtaMassage.org/amta-cos). Steiner Education Group's chain of accredited massage schools has 17 locations, from Las Vegas to Miami, and offers 50-minute massages by students, usually Saturdays or Sundays, starting at $25 (SteinereEd.com).
