Before I left on my LDS mission to New York, I was having quite a fun time socially. Since I was leaving on a mission shortly, I was able to date without having to be serious. My group of friends had made friends with a set of girls from the southern end of the valley. We hung out with these girls quite a bit, they were a fun bunch. Most times they would call us and we would have this huge group date.
My friend Angie called me up and asked if me and my friends would be interested in going to a Girl's Choice Dance. I had no problem with that so we coordinated so all my friends had dates. It was a fifties style date, we were asked to dress accordingly for it. I borrowed a leather jacket and Lared and I greased our hair with Vaseline. Isn't Vaseline water proof? Yes, it is. I didn't know that at the time though.
We went on the date and we had a ton of fun. Angie and I hung out longer than everyone else and I didn't get home until late. It was around two in the morning when I came home and I was cold and I wanted to get this grease out of my hair. It was so cold (how cold was it?), it was so cold that the pipes froze. I had no hot water at all. My mom got up and told me as I tried to run the shower. I told her what I did and she laughed. "Didn't you know you shouldn't put Vaseline in your hair? It is waterproof!" Yeah, I obviously didn't know. I know what you are thinking, why couldn't I just put some hair gel in my hair. Straight answer. I have absolutely no clue at all. But what's done is done. So we boiled some water and it didn't come out. So I went to bed and went down to my grandparent's to use their hot water.
I also tried a variety of soaps, shampoos, Soft Scrub, pretty much anything but to no avail. It just didn't want to come out at all. My scalp felt so rare after awhile, that Soft Scrub burned like nothing else! It took a few weeks for my hair to comeback to normal.
So here is a tip. Don't put Vaseline in your hair. Use hair gel.
