I'm with Junk on this one for one simple reason. From what I have read, most cases of MPB show high levels of bloodstream dht. I am not saying that surface/scalp levels of dht are not also elevated in alopecia sufferers and may contribute to the shedding. But, high levels in the bloodstream are definately a major factor in most, if not all cases of mpb. That is why there are many success stories with propecia/proscar, and now
avodart. Internally taken meds that lower bloodstream dht do work. Topicals do lower scalp dht and you may get some growth from those (minox,spiro,etc), but the research I have read indicates that the hair growth from the topicals is typically tiny, weak, fuzz-type hairs. Not only that, those tiny hairs are also dependent upon continuous application of the
topical solution you are using. If you stop minox, those tiny minox-dependent hairs will fall out. Similarly, with propecia or
avodart, the battle is a lifelong commitment, you must continue use to keep from losing hair. However, taking a pill is much easier than applying something greasy to your hair and leaving it on for hours at a time every day. I refuse. I take
avodart & use Nizoral 2% shampoo once or twice a week, thats it. If I had to do only one, it would definately be the internal med, because I know that works.
