Dawn,
I am normally one for removing the stray hairs but with your client, you've got this great sun highlighting her head. I would remove a few but do not try to remove it all.
Also if you are going to be cloning things out, I would remove that white pole. Fairly easy to do and it wont look like she has an antenna.
If you want to fill in some of the hair that could work while still keeping the sun halo.
You might search the web for some ideas. If you move down the following page, this article talks about taking chunks of hair and doing fill in work.
http://www.peachpit.com/articles/article.a...33&seqNum=3PS - I know this won't help for this client, but I generally suggest bringing an assistant to keep an eye just on the models. This prevents crazy hair and bra straps. Of course I do this only as a way to save money. Getting it done in camera versus in computer...
