Wavyroo, here's the link to the recipe:
Quickie Homemade Protein Treatment!!
It's the one posted by ththd.
I added a little bit of coconut oil and hair conditioner to mine, used apple cider vinegar for the vinegar. I just put a cap over it and a towel and left it sit on for a while. (I dunno if that's a bad thing?) I really needed protein, Because my hair was so course.
