You don't specify if the hair colours have to be all different, or is not drawing in the hair at all would be a choice.

If all different :
number of ways = 64 x 63 x 62 x 61 = ...

If repeats are allowed:
number of ways = 64^4 = ...

If not drawing the hair at all is a choice, then
start the above with 65
