Title says it all. Ive read hundreds of posts and all i can find is conflicting views. i dont understand how the results from rogaine liquid can be so different to that of the foam. if they both contain minoxidil, how can one be better than the other? i can only think that the foam would be difficult to absorb if you have long hair, but if you have short hair it shoulnd be a problem. Also the liquid causes a lot of irritation. any thoughts on this difficult topic?
