I use IAGirl's protein treatment weekly and use daily products with protein. I bought some Colorful Neutral Protein Filler from Sally's. It's a pretty cheap liquid. I add a few drops to my conditioner and it works well for me. There are a few curlies here who put it in a spray bottle and spritz it on straight. That may be a bit too much for me but your hair may like it.
