I haven't tried liquid. At the time I actually couldn't find any stores that sell it, only foam. But the foam does appeal to me more for the fast drying effect.

Minor Update- for those people who are silently listening.
I'm still shedding like a beast, and my density continues to take a huge hit. But I've noticed the hairs that are shedding mostly aren't miniaturizing further, they are maintaining their ground. And in some rare cases the hairs are even thickening slightly at the root.
This gives me a sliver of hope. I just hope this shed passes and isn't a chronic reaction to the medication.
