Hair drinks water like her plant?

Lia and I had this cute conversation few nights back.

Lia: "Mommy, I wash my hair and then it'll grow long, right."

With that, I started thinking about the massaging of our scalp when we shampoo our hair; of which does promote hair growth...

Me: "Yes. :) How did you come about that? Ah Ma told you?"

Lia: "Because like my plant, when it drinks the water I give, it'll grow tall. Then my hair drinks the water when I wash it and it'll grow long!"

Me breaking into laughter: "Oh, ya... No, not that way, Lia..."
