are there any charts showing hair count difference in using once a day vs twice a day. theres got to be a reason that they say use twice a day, but i feel they just do it to give it a better chance to absorb. bryan or anyone have any data on difference between once or twice a day. i personally switched to once a day but have hair alot shorter so easier to absorb and cover more area easier, also I run the head under hot water for a minute then towel dry then wait a minute then apply. I feel absorption is the key to rogain and not using it 2 or 3 times a day. i also think guys useing the foam should keep their hair no longer then an inch because its sooo much more easier to apply and better ur chances of getting sucess.
