i also dunno why it works actually. this was taught to me by my
stylist de. cos last time i forgot i going cut hair then i applied
wax... then my stylist wan to wash my hair then she "scolded" me,
ask me why i put wax. then she ask me"eh since u use wax hor, do u
know now to remove the wax ma?"
Then when she washing my hair, she told me to use conditioner lo.
it worked at the salon, i tot salon shamppo more power so i dun
believe at 1st also 
came home and try, can work leh. u all try out then tell me can or
not lo
