Why do you think this would be "amazing"?
This product is not advisable for a couple of reasons:
- any type of minoxidil for treating Androgenetic Alopecia/male pattern baldness (liquid, foam) is supposed to be applied for at least 2 hours for significant results (confirmed). How long do you want to stand in the shower? When rinsing the shampoo out of your hair, you will also rinse out the minoxidil.
- minoxidil should not be used on a wet scalp because of systemic absorption (confirmed)
- finasteride needs to be metabolised by the liver to have any effect, thus it needs to be ingested (don't know if this is confirmed, I only read it recently in a post of a forum member who is usually well-informed)
