My hair is too short to do just the ends, so when I tried baggying I did my whole head. I was using Hawaiian Silky 14-n-1 on my roots, plus moisturizer and oil on my ends. 2 nights in a row and my hair smelled bad on the 3rd day. My head never felt "hot" and it didn't make me sweat. But I am going to assume that the smell was from the baggying. I will say that my hair was soft, kind wettish but that evaporated quickly after taking the bag off.
Anyway, I guess I am going to have to relegate baggying for those times when my hair feels really dry or is breaking. Or maybe not use a glycerin product...
