I left the barber shop yesterday with a baggie half full of my freshly cut hair. These barbers knew a lot about hair, more than I wanted to know. We discussed human hair and hair from a Sable, mouse and Indian rat. I discovered several "things" about hair from these 5 gentlemen, and all of them joined into the conservation because the shop was not busy at 8:30 am. The more important discoveries as they relate to survival were:
Hair is a protein compound, unlike protein found in meat, which is full of iron and other ingredients that are good for you.
Human hair is solid, unlike some animal hair, which is hollow.
A protein compound does not burn well at all (understatement).
Long story short: I discovered that human hair will burn, but once the heat sorce is taken away from it, human hair stops burning. I used a bic lighter and the hair singed at first and then grew into a small flame. Take the lighter away, the hair stops burning. The flame was small (under an eight of an inch) and not hot enough to light paper. The hair basically melts into an ash, will not burn on its own and gives off insufficient heat to ignite, say very small and thin wood shavings.
For me the "bottom line" is untreated, raw human hair, which does contain natural oils, is a protien material poorly suited for tinder to start a fire. I would be better off using the fire source used to burn the hair than rely on the hair itself to start tinder burning.
Now Mr. Hershal, owner of the barber shop, swears-to-be-damn that Indian rat hair, which is hollow and only partially comprised of protein, will burn like an old wooden barn...the kind that has " Chew Mail Pouch Tobacco " painted on the side of it. OK, I thanked him for that information.
There is one use of hair that I believe would work for a survival situation if you find water with fish in it. Cut a strand of hair about 1 to 1-1/4 " in length and about half the thickness of your little finger. If you have a red head or blond standing near by ( or get hair that is colored) that would help also.
Twist about a quarter inch of the hair at one end and secure/ wrap it with an adhesive. ( more on this later). What you have is a dry fly without a hook. If your survival kit contains a fishing hook, secure the "hair" fly to it. If you do not have a commerical made hook, fashion one from the surrounding materials...this of course is a topic for another thread.
I secured/wrapped the end of my dry fly by using a long, narrow piece of adhesive taken from a Band Aid located in my survival kit. From the same kit I located a fish hook and very thin piece of wire and secured the fly to the hook. My survival kit also had a piece of corn in it and I placed the corn onto the end of the hook as bait. I'm ready to go with a rig that is "fish attractive." If no survival kit is available...well I am open for suggestions. One might be to use pine pitch taken from a tree, etc. GUARANTEED: I will use this rig on the weekend of Oct. 12-14, when I'll be bow hunting, fishing, hiking, camping and just surviving.
I purchased one each of the thee survival kits offered by Jeff Randall and they are VERY nice, extremely practical and stocked for serious survival. If interested:

Thank you for the "hair splitting" question.
