Question: I’ve recently started on Proscar, under the advice of my GP, for a 1cm thinned area of my hairline. I’m wondering if i start using additional minoxidil on the area, and while still carrying on with my Finasteride dosage, I stop the minoxidil say a year later, what would happen? Basically, would the finasteride be able to hold what minoxidil may thicken/regrow?
Answer: Proscar contains 5 mg of finasteride as supposed to the 1mg contained in a daily dosage of Propecia, which is used to treat hair loss. As finasteride is not dose dependent, taking 5mg will not help your hair loss more than taking a daily dose of 1mg. Proscar is only licensed to treat Benign Prostatic Hyperplasia, so your Doctor must have considered other factors prior when prescribing you Proscar.
Minoxidil works in a different way to finasteride/Propecia, so using them simultaneously can often be a very effective way to treat hair loss. Minoxidil will help to stimulate regrowth on a receding hairline, as long as you start the treatment before the area is completely shiny and bald. With the majority of cases that I see, the hair regrowth requires maintenance by using the same medication. Regrowth from Minoxidil requires Minoxidil for sustenance, and you will generally notice deterioration within six months after ceasing to take finasteride.
