I would shoot a brunette. Guy or Gal.
Make sure there hair is not under or over exposed.
T grain films can fool you so somtimes so it's best to make a print. 
Make sure the hair is printing with the detail you need.
it is surprising how thin they can look in the neg and still print well.
So make sure the one thinner on your bracket also can not still be printed with
proper shadow detail (shadows=dark hair)
And that will also tell  you if your development needs to be changed to fit the
kind of contrast you like to print with.

	or you will end up with a hair raising experience!
