How do i silk wrap my hair?

I am african american. I can pretty much do anything to hair. I learned to do different things experimenting. My co-worker came to work with a hair wrap. She always has a hair wrap, but this time it was silky. In other words it looked like the human hair that you buy. I asked her how did her beautician do it and she said she don't know. I know she is not lying because she doesn't know how to do anything to her own hair but wash it. Can someone please help me out and let me know how I can do a silk wrap in my hair to give it that silky look. What do I need to buy, along with the process.

Your in luck, I just got on done yesterday. What you do is wash your hair, sit under a hood dryer until damp, then blow dry with a comb attachment until dry. Then you flat iron your whole head and wrap it. Put some saran wrap on it, and sit under the dryer for 10 minutes. Unwrap and your good. I don't know where you live, put in charlotte they do these in walmart for 28 dollars
