Tease a little
With a teasing comb or a fine tooth comb you can create some volume at the root. Take small sections and back comb from a third of the way down the hair shaft to the root. The key to teasing is to do a little at a time and gently comb out to smooth and soften.
Hairspray
Using a light hold spray at the root will create some volume as the hair will not lay flat and smooth. Remember to spray the hair in sections and not directly where it will be seen, for example spray underneath the top layer.
Dry Shampoo or Powder Spray
Using a dry shampoo or powder spray not only soaks up oil but creates some body and volume at the root. Remember to apply little by little, you can always add more but you can not get it out without washing.
