correct way to apply regaine foam?

[jman91]

I am just starting on regaine foam 5% and was wondering if there is any harm in using more than it states on the directions.

It says to use about half a cap full per application but as i have diffused thinning all over the top and crown this amount simply does not spread around the whole affected area.

I assume those guidelines are more about getting the bottle to last it's intended 1 month and not so much about potential side effects from over use.

to get the foam to all parts of my head i need to use about a cap and a half, has anyone heard of this causing any risks to your hair or health?
