global I asked this in a different thread where you gave a link for genhair.
how does the drying time of genhair product compare with Dr. Lee's #500 minoxidil. How long does it take to dry.
If you have irritation, I suggest Dr. Lee's #500 minoxidil. it is not ppg free. It contains less ppg. I got irritation from rogaine, not from this. if this irritates choose ppg free minoxidil.
