I think you can start with an oil now - it might be better to start with jojoba if you can find some - the reading I have done suggests that it's the closest oil to the natural oil produced by our skin - so it may help with the bearddruff especially. With the length of your beard for now you probably only need 2 or 3 drops daily. It would also be useful to find a natural boar bristle brush to distribute the oils and help to train your curls a little - at least in Canada I was able to find one in both my local grocery store and pharmacy.

And as much as I would like to take credit for the moustache thread - it was started by Paul (PMKinFTW) - a true moustache guru. His thread is another very informative one - especially if you want to see expert moustache shaping!
