I am currently baggying. It's a personal challenge for myself and then I joined the 2008 LHCF Bootcamp that fit in with my 2008 regimen. I am hearing a lot of ladies mention vaseline...well vaseline is actually the 1st product that was used for baggying as far back as I can remember. I still have a printout somewhere around here from yahoo bhsgo circa 2000-2001 where I first read about baggying and it was simply apply a moisturizer to your ends, coat with a layer of vaseline to lock in the moisture, secure your baggy on your ends under your scrunchie or phony pony and go! I have seen a lot of different variations of the baggy method here and there, but ultimately, vaseline was and still very well may be, the ultimate moisture locker. 



...YES.
But it does work for me
I usually use whatever moisturizer I'm using at the time.
