He hee, if you're looking old, then I'm in serious trouble! I have totally done the non-dispersed oil slick thing.
Here's how you get around it if you still want the oil in there: Make up the PT about 20 to 30 minutes before you need it. It will begin to cool and "set." Then take an immersion blender or electric beaters to it or put in in a blender and mix it very thoroughly. Use right away.

Protein spray...
Great idea, SolidGold! I have not tried this yet, but I think I'm going to make one. Oh, the challenge! I have some hydrolyzed proteins, but if you want to start making your own you can get some "Neutral Protein FIller" from Sally's and dilute it with water in a spray bottle. http://www.sallybeauty.com/Neutral-P...?cm_vc=SEARCHI think you'd use 1-2 tablespoons in 1/2 cup water. That might be strong. Or better yet, in chamomile or nettle herbal tea for shine and body. A little conditioner could definitely go in there.

Ouidad makes a spray called "Botanical Boost" which is basically what I described above (and totally CG), maybe more conditioner-y, it is $16 for 8.5 oz, but you don't use much at a time. I did buy a sample-size. It is very nice if you just want to buy a spray-on protein-rich product. Like a super-light conditioner. There is almost no scent at all - Huge plus for me!http://www.ouidad.com/Botanical-Boost
