you know, my hair band keeps coming loose especially during tennis practice. and i've come up with three possibilities of why this is happening:

1. my hair loss is just too serious that i don't have as much hair as i used to, thus causing my hair band not to be as tight. 
2. the hair band simply became loose due to old age. (i have been using the hair band for quite some time now)
3. my hair became softer and smoother after treatment, therefore the hair band did not loosen, it slid down my hair while i was busy playing tennis. 

guess which one i chose to believe? ;]
