Since you just want a hint, use a 20.

id use 10 or 20 you dont need to worry about any lift so deposit is all you need. if you goo over 20 vol you myay loose some tone... also sense it is so dark already you should use a fairly high intensity to see it. because hair at that level has the least amount of visable tone!
