Regaine Rogaine Foam Difference?

After getting through 2 bottles of USA Rogaine Foam, and then recently switching to Regaine Foam you cant help but notice the difference.

The UK Regaine Foam seems thicker and seems to have much less alcohol in it, with the Rogaine the alcohol smell was pretty strong while it was evaporating and you could feel the tingle on your scalp.

Anyone else tried them both and noticed any differences?

I have never tried the Regaine version so can’t comment.
