DNA extraction methods for hair?
I've been trying to figure out something that works for some time.  I have recently tried 3 cheap protocols using commonly available lab reagents.  I was using buccal samples (0.2 ml of spit). 

1) Boil the sample in Tris EDTA Buffer
2) NaOH Extraction
3) Direct N Lyse 

I compared them to a genomic DNA extraction kit (FAST DNA Prep - MP Biomedicals).  

I have heard lots of people use NaOH extraction to get DNA from tissue and cell preps, but none of the first three worked for me after 2-3 tries.  One of the people in my lab said that I could replace the bead beater with vortexing with glass beads.  

I tried vortexing with beads with all four methods, including the kit and only the kit worked.  I got a PCR result from control primers. 

When you look at the costs of getting all the ingredients for the buffers kits are not so expensive - $1-$2 per sample.  

A lot of these kits can handle solid animal tissues, though the one I have doesn't specifically cite hair.  I would try it out.  

I guess the point of my post was that there are lots of simple sounding published methods, but they don't always produce results without a bunch of debugging.  I know alkaline lysis has worked for several people I know and is the basis of the kits.  Its pretty simple. 

That's my experience anyway.
