Note that I am also using texture mods, which are optional and not required for the head morph. Just follow the instructions included in the description of that mod and you'll have the hair. The particular hair I'm using is called Foam Summer. You don't have to use the hair I used, but you do have to use one of the ones found in the Hair Mods as DLC mod created by ElysiumFic.
Please note that in order to use the head morph file without your game crashing on save load, you must also use the hair mod. You will need to import the head morph following these instructions using Gibbed's Mass Effect 3 Save Editor (r90). I find her appearance to be very pleasing to the eye, and thought I'd share her here!
