Rogaine: Scalp
built 643 days ago
The whole issue of hair loss drugs such as Propecia / Proscar (finasteride) or Rogaine (minoxodil) only working in the crown/vertex region of the scalp for hair loss is totally false. The reason these two companies have to say that in their advertising is that the studies they conducted on these hair loss medications were done in those areas, and, because of the strict rules of the FDA, one can only say hair loss drugs work in the area in which you studied it. I have had many, many hair restoration patients given either or both hair loss treatments who have benefited in all other areas of the scalp, including the midscalp on top, the frontal region, and even rarely in the balding recessions in front.

There have been cases of allergic reactions to minoxidil or the non-active ingredient propylene glycol which is found in some forms of the topical version, such as Rogaine. Large amounts of minoxidil can cause hypotension, and it has been found that using petroleum jelly or tretinoin on the scalp with minoxidil can cause too much of the drug absorption by the scalp, as can using the drug on sunburned scalps.
