I have never used rosewater for my hair, but have been using it for my skin. 
One of my customers here ( I have a flower shop) would come by and i would give him rose petals from my older roses that i felt weren't sellable anymore, he would take them & in exchange he would come back a few weeks later with bottles of rosewater for me.  He also used them in some all natural facial cleansers and skin lotions that he made, good stuff.  I have since learned how to make my own cleanser, but have not tried my own rosewater yet.  As posted by Galadriel, I was always concerned that the roses being used were in fact commercial roses, and not garden grown.  I,m sure that the growers of these roses do use certain pesticides and growth agents, not to mention the floral preservatives used in the water on my end of the process.  I'm sure that none of that is very good for the skin or hair.  However, I will say that I was always pleased with the results of the products, they made my skin feel very soft and healthy.  I am going to look into my local health food store to see what they carry, after reading this thread, I am curious as to the effects on my hair.
