In order to enjoy the offer (below), I went Chapter 2 salon @ PS to dye hair:
Grand Opening Promotion of C2 Plaza Singapura
I purposely chose the creative stylist (i.e. the senior stylist) to see what the advice the staff will give. The lady was sweet-looking and friendly. I won't have guessed that she is the salon manager. (Wah!)Then i signed up for the treatment package. It is worth it if u go with frenz or u have hair (thick, flyaway and dry at the ends but oily on the scalp) like me.

I also bought leave-in conditioner which i really needed, a daily shampoo and conditioner for colored hair. But in total, it costs me a bomb. I must save 75% of my next paycheck to recover my spending.
I have the smiley face (shown on the poster above ^_^), since i left the salon.
