Factual error: The serum is transported by blood. Hair has no blood traveling to it, only the root. So, unless Bacon shaved his body clean, his hair wouldn't have become invisible, likewise all of the fur on the gorilla.

Linda: Let me tell you a little secret. The concept of Sebastian is much more appealing then Sebastian himself.
Trivia: Whenever Sebastian is invisible and interacting with the other characters, Kevin Bacon's voice would be broadcast throughout several speakers randomly hidden throughout the set. This was done to make the reaction more genuine, since the actors would honestly not know where his voice was going to come from next, just as the characters would not know where Sebastian was.
Question: What is the song playing when Kevin Bacon is driving his car? It wasn't "Power Struggle" by Sunna.
Answer: Do you mean the scene where he is invisible, wearing his mask? If so, the song is called Charlie Big Potato by Skunk Anansie.
Answer: I checked the movie's credits (original concept, I know) then I listened to the song in the film and found the lyrics at http://www.letssingit.com/sunna-power-struggle-1bdk7zz.html and http://84210992.home.icq.com/lyrics.html and I can assure you that it was, in fact, "Power Struggle" by Sunna.
Answer: It's actually Skunk Anansie. I know this song from memory and can attest as a fan of the movie and the scene.
Suggested correction: The serum could have been absorbed by the roots and made its way to the tip of the hair strands (similar to colored water going up a piece of celery, changing the color of the celery).
Mammal hair is not porous and is not subject to capillary action.
