minoxidil once a day? 15% or 5%?

[redhot2k4]

I am looking to apply minoxidil only once a day, it just isn't practical to use it in the morning, even foam leaves my hair looking ridiculous!

I can't use anything with PPG in due to severe irritation so I am thinking of trying minoxidilmax.com

As I will only be applying it once at night, should I use the 15% solution or will the 5% be ok?

I read somewhere that the difference between one application per day and two applications was minimal as the half life of minoxidil is something like 22 hours?

cheers

I think you should start with 5% and if you feel that you're loosing ground because of one time per day application than switch to 15%.
By the way where did you read about half life of minoxidil is so long?
