Hello!
I wish I could send you some of this sebum of mine. My scalp is quite oily.
What I would recommend to you are jojoba oil, apricot kernal oil and a product called UNpetroleum. I think the latter is by Indigo. The jojoba oil is relatively light and is most similar to the sebum on your scalp...very compatible. Plus, it has balancing properties to the scalp: encourages sebum production and breaks it up where needed. The apricot kernal oil is extremely light. You could apply it nightly, if necessary, and as with the jojoba, would not have a lot of build-up. If you would rather have something like a pomade, the latter is the way to go...no petrochems in it.
I agree with the person who suggested massaging your scalp. That encourages sebum production. Try to massage at least twice weekly and you might use a warm oil.
I would also suggest an oral supplement of essential fatty acids like flaxseed oil. If you are taking biotin, let me know how much you are taking because the right dosage will also kick up major sebum.
It's actually VERY hard to clog your follicles and significantly impede hair growth.
Cheers,
Jade
