Something that's helped me with hair in the past:
Instead of thinking of hair as individual strands, try to consider it as though it were a bunch of flat ribbons. The reflectivity is very similar to ribbons, and it'll help you think about the form and the way that the hair lays on the head. Indeed, many hair stylists and barbers are taught to layer hair in this way as well. Also, trying to consider individual strands is an easy way to get too detailed much too quickly, and to overestimate the range of your values.
