Why Does Minoxidil Packaging Say to Only Apply on the Vertex?

I recently received topical generic minoxidil solution and it says that it is only to be used on the vertex and is not for frontal hair loss. Is this true, will applying it to the front hairline be useless, if so, why?

Also, i would like to use a non-finasteride supplement in addition to the minoxidil, can you recommend one, or which ones are most popular??

The FDA only approved claims for crown benefits for minoxidil so the manufacturer complies with the FDA ruling. I don’t think it’ll be completely useless in the front, but the success rates are likely higher in the vertex than in the hairline.

There is no good substitute for finasteride in my opinion, but a popular natural supplement is saw palmetto. Popularity and reliability are too different things, however.
