Rogaine - irritation: foam or liquid?

[Maelstrom]

Is there any concensus about which is supposed to irritate the scalp the least?

Would appreciate any feedback but especially from guys that have used both.

Thanks.

C'mon guys, I know you gotta have opinions on how irritant/non-irritant these products are!

Give me your thoughts even if you've only used one or the other at least!

Foam all the way. I spent nearly a year scratching the hell out of my head, went onto foam AND been on it now for around 4 months with no more itching. Well worth the extra expense. (£50 for 4 months worth in the UK)

From what i've read, foam is way less irratating to the scalp. I did read that it may not work as well as the liquid however, but I think each person is different, What may work ok for one may work great for another and visa versa.
I am trying to find out if the foam would give me less forehead wrinkles as the liquid makes my forhead look like a 99 year old guy!! Makes me want to get Botox injections!
