I haven't oiled my scalp since I was a teen, and I'm almost 39. I seen an Oprah show years ago, where her and her stylist were begging us to stop "greasing" our scalps, saying it clogs the pores (as CamamelHonee mentioned), and that a little oil on the hair itself if needed, and a good conditioner was all that was really necessary, to maintain natural oil balance. Many people firmly believe in oiling their scalp, but for my daughter, she's 10 (beautiful hair, never had her scalp oiled) and myself I choose not to oil the scalp. We lightly apply essential oils to the hair when wet.
