I've done that protein treatment 5-6 times, and my hair never gets crunchy or feels dry. I don't usually use very much olive oil, just a few drops. I usually put in a little bit of conditioner instead. I did an experiment once where i didn't add oil or conditioner to the treatment, and my hair still didn't get crunchy or dry or anything. I even made a double recipe to make sure I covered all of my hair. So my hair didn't hate the gelatin, but it didn't love it either. It does help my waves perk up a little bit, but nothing drastic. I've been meaning to try other types of protein, but haven't really gotten around to it. Try searching for the beer rinse... HTH!
