BHD, stick my Regaine (brand) on my scalp, 2-3 hours later it is still greasy on my skin and damp in my hair !!
I also find I need to put around 1.5ml -2ml each application (twice a day that's 3ml-4ml a day) just to get the stuff everywhere, it makes little sense to me that if some guy is trying to fill in a bald spot at the back of his head he should be using the same amount as someone who is trying to treat the back, top and front !!!
I realise there is an increased risk of side effects from systemically absobed minoxidil at this extra amount, but the way I see it is that Evil Knievel spent the whole 1970's taking not disimilar risks and he's fine now.
