Why Do You Only Recommend Starting Propecia and Not Minoxidil Too?

Dr. Rassman,

I’m a 32-year-old with a Norwood 2-3 pattern in the front and some very mild but immistakable loss in the Crown. I very recently started taking propecia and am strongly considering trying that in conjunction with Rogaine Foam. Your esteemed colleague, Dr. Bernstein recommends the use of both of these products simultaneously, right off the bat. You suggest that one hold off on Rogaine until propecia has been shown to be ineffective, as it causes “dependencies”…

Not to create friction, but what is the source of your disagreement on this? What do you mean by “dependencies”? I don’t understand because doesn’t propecia create a dependency as well? (i.e. if you stop taking it, you lose all of the benefit)…

There is no disagreement. I would also recommend Propecia and Rogaine. But, think ahead for a second:

1. Once you start both Propecia and Rogaine, you need to take both for life.
2. You will never really know which medication is working more or less if you start both at the same time.
3. Rogaine can be difficult for many men to follow the twice a day application (a pill like Propecia is easier to deal with and faster to take).

If you can accept the above, I agree you should take both Rogaine (minoxidil) and Propecia (finasteride 1mg). Both create the same dependencies and I’ve never tried to downplay that. If you stop either medication, the benefits received (maintaining or regrowing hair) will be lost, therefore you will depend on both to keep your hair loss in check. The medications work differently, so finasteride can’t retain hair grown by minoxidil and vice versa.
