I just picked this up for myself after finally remembering to actually look for it when I went to sallys. So far I have used it 2 different ways. I'm currently putting about 10 drops in an 8oz spray bottle with about 1 tbsp of condish for a second day refresher and it seems to be working well. I also added some to IAGirl's PT for an extra boost and that worked out well too. I'm not sure my hair likes protein but I am growing out a lot of heat damage so I use it on the damaged ends of my hair more than my new growth. This seems to be working out for me, at least till my hair changes it's mind again, lol.
