I NEVER use a lotion on my head. ANYTHING that has any oil in it, (and all lotions have oil) trap moisture in the skin (that is why they call it "moisturizer"). The more moisture I trap in my skin the hotter it gets and the more it wants to perspire to cool me off.I forgot to tell you; this is why I never use an oil based sun screen on my head either. I only use Neutrogena sheer mist spray sunscreen on my head because it:a. goes on dry and thus allows the skin to wick moisture through itb. is not oily and does not exacerbate my head perspiration like all of the other sunscreens do
