This is a funny commercial which promotes the Rejoice Shampoo. It's in Cantonese, so I believe that it's a Hong Kong commercial. You know that almost every shampoo company declares that after using their shampoo, you'll get very healthy smooth and silky hair. Indeed that's what every girl wants. Maybe because of this reason, the commercial was made in this way, showing how silky and smooth the hair is. See the funny and awkward situation in this funny shampoo commercial.
