suggests that twice a day is indeed more effective than once a day, on average. However, there is large variation among users, so it may not necessarily make a difference for you individually.
I've tried the foam, the regular liquid, and dr. lee's liquid (#500).
Regular liquid caused dandruff and didn't dry readily, so it left a greasy residue.
Dr. Lee's caused less dandruff and leaves very little residue unless applied too generously - then it leaves a white powdery residue.
Foam...
What puzzles me is who decided that showing efficacy for growing hair on the top of someone's head does not entitle the maker even the suggestion that it might help on the front... These are not completely different body parts!
This only bothers me because I think a lot of people who could be...
There is a study on pubmed (sorry can't find link right now) where participants used rogaine 5% 2/day for 1 year and then half of them switched to 1/day for the subsequent year while the rest stayed on 2/day. At the end of the second year, the group that switched to 1/day did have lower hair...
It's probably better, because it tends to produce less irritation than non-micro retin-a, and it is much less prone to degrading from light exposure.
However, beware the light-headedness. It means the minoxidil is reaching significant levels in your blood and this is a health risk. You may...
Given that the site allows anyone at all to submit 'customer' reviews, it is already obvious that they should be taken with a grain of salt. However, I just noticed some particularly flagrant examples - for a product called Aromatase-7. It has a stellar rating score but most of the reviews are...
I have seen many posts from people who swear the liquid worked better for them than foam, as well as many posts from people who swear the opposite. So there may be a wide range of individual responses.
In the 2007 study done by the makers of rogaine foam, the aggregate/average result was less...
To everyone complaining about my not posting the full-text of the study, I cannot easily do so because I only have a hardcopy. However, it is not necessary to pay $ to read it, as it is available at many libraries. Go to pubmed, search "rogaine foam", and you will get the abstract and citation...
Aren't there any copyright issues with posting the whole study here?
And re: placebo effect, it wasn't an actual placebo effect, as in growing more hair - rather, they believed they had improved when an objective observer didn't see the improvement.
Just yesterday I obtained and read the full-text of the recently published clinical trial results. (J Am Acad Dermatol. 2007 Nov;57(5):767-74.) It is shameful how misleading the promotional information for Rogaine foam is about its effectiveness.
People on these boards who are thinking of...
