There's another potential explanation for the loss of dandruff: to many cleansing practitioners, dandruff is the result of excess protein not being processed by the liver. If the Oil Pulling does act as a temporary "second liver" and helps increase the functionality of the (actual) liver, your loss of dandruff could be because the scalp is no longer needing to be used as a secondary elimination pathway. All because of a better-functioning liver and gallbladder.
