Mixing minoxidil brands?

[cmudave]

The other day I was at walgreens and I noticed that the Walgreen's brand minoxidil was on sale 2 bottles for $20 so i had to jump on that. (The sale is still going on if anyone is interested) Right now I am using rogaine foam, and i was wondering if the mixing of the brands would effect the results at all. Thanks in advance.
