The Cost of Attendance (COA) is the annual total cost amount (in average) for attending to the educational institution like colleges and universities. This cost includes tuition, campus room, personal expenses, books, supplies, transportation and so on.
The COA is important because it helps prospect students to plan their future education and prepare for it, financially, physically and psychologically. This annual cost variates depending on the university and the level of education the person wants to access.
Repeated bleaching is not recommended since you're putting yourself at risk of overprocessing and breakage. If you do bleach again, make sure to wait 3 weeks to give your hair cuticle enough time to heal, close and lay flat again.
