Whitening toothpaste?!

I just bought colgate whitening toothpaste, I am not sure if it works for me. I have yellowish teeth because I am drink milk tea often.

Anyway I bought the tooth paste today at Watsons. I also bought Sunsilk shampoo for my hair. If purchase the Sunsilk brand shampoo or conditioner RM20 in a single receipt and above can get freebie of a comb and a mirror. :D

I used Sunsilk shampoo, today decided to purchase the hair fall and prevent hair damage shampoo. :D
