Good, a perfect opportunity for my rant on rogaine foam:
Used it for 6 months and it was a disaster. All I expected was maintenance of the hair grown from liquid minoxidil (which was a lot btw), but it couldn't even do that.... It actually made things much worse. But to be fair, I did make the switch to foam at the same time I made the switch from finasteride to dutasteride. So I'm not sure whether foam or dutasteride is to blame, or whether they're both equally to blame. But I will say that foam is at least partially to blame because I switched back to liquid and was able to regrow a bit of hair back.
But even putting results aside, I still think foam is a hugely overrated product (well, it was overrated at the time I bought it, now it seems like the hype died down). With liquid, the dropper made it so easy to apply it directly to the scalp where you can spread it using your fingertip. With foam you had to put it on your finger where it immediately starts to turn to liquid due to the heat from the finger. Then you had to some how get the foam through your hair and onto the scalp. By the time it does get through to the scalp, most of it gets in your hair. I guess it wouldn't be an issue if there was very little to no hair on that area, but for the people who just need it to maintain the hair, it's a pain. And because most of it goes to the hair, it obviously becomes really wet, which would negate the supposed "faster drying time" compared to liquid. Easier to apply my butt.
Then there's the cost. Not only does foam cost about twice as much as generic liquid, but the supposed one month supply of foam doesn't even last for that long. Seriously, I only used foam once a day on my hairline and one bottle would last me just about one month. Compare that with the liquid bottle which would actually last about 5 months.
But if there's one thing that foam does better than liquid, then I would say it's the itch factor. I didn't feel any need to scratch my scalp whereas with liquid, I was fighting the urge to scratch so badly. However, the itch isn't really an issue after a few months when your scalps gets used to the product.
I was an idiot for buying a 6 month supply of that crap without even trying it out first.
