You could use a drop or two of jojoba oil as a leave-in. Or you could try Giovanni Direct Leave-in (or even leaving in their 50/50 or Silk whatever conditioner). There's a little soy protein in it but it probably wouldn't give you any issues.
If you're concerned about protein, you're definitely gonna want to rethink that Joiwhip because it has a lot. Re:coil
has protein too.
I really don't think protein needs to be avoided until you've confirmed that you have a problem with it personally though. Protein is only a "bad" ting for certain people and even then, sometimes you can be sensitive to one type and not another.
Another mousse I'm loving right now (that had less protein just silk amino acids which my hair loves and are totally worth a try, as is something with hydrolized silk) is Biosilk Silk Mousse. Lots of people love the Paul Mitchell medium hold sculpting foam or whatever too but I haven't tried that one (yet
If you can get your hands on some Jessicurl Aloeba
(either by ordering or through the swap board) I can't rave enough about the combo of that and Re:coil
. I was less impressed when I layered them but now I mix a tad of Aloeba
and a tiny bit of Re:coil
in my hand first and emulsify really well before applying and it *really* makes the Re:coil
easier to distribute evenly and counteracts any dryness form the Re:coil
(or Joiwhip if I use that over it).
