I just received the Xyon topical as well. In the instruction booklet it mentions the two pump every other day method for covering larger areas. Personally, I'm unsure how to proceed as I would like to cover the whole top of my scalp, however, 2 pumps worth seems like a lot of the drug all in one shot. I had a thought that a person could alternate scalp regions each day - front half one day back half the next day. This morning was my second application. I tried to cover as much area as possible with one pump. In terms of the actual application, I'm not sure if I'm getting more on my scalp or more on existing hair.
