It can take hair a while to get used to a CG regimen and in the meantime, it can be a little odd. Common complaints are greasy roots and/or frizz. There are a lot of different possibilities, anything from a product ingredient to application technique that could be the culprit for your fuzzy hair. You may not have needed a full dt, for instance. We'll be better able to help you if you tell us exactly what you did do, including what you used on your hair. Also, if you know your hair properties (texture, porosity) that can help pinpoint too. You can read up on those here.
