I don't "know"
. I draw a conclusion from the information that is available. The information from Merck states that you need to use the medication for at least 12 full months to determine if it will stop your hair loss. It only makes sense that if any regrowth were going to happen, it could take longer than 12 months for it to happen.
It is important to note that Propecia itself is not a growth stimulant. It is a growth enabler. It enables hair follicles that can still grow hair to grow hair by blocking the hormone that is preventing them from growing hair.
Rogaine on the other hand is a growth stimulant. It stimulates hair follicles that can still grow hair to start growing hair again.
These two medications, Propecia and Rogaine, do two different things that compliment each other.
The laser comb increases the caliber and quality of the hair that you have, including hair that has regrown from using medications. This effect makes your hair look fuller and more youthful.
None of these treatments will grow hair in areas that are completely void of hair and have been that way for a long time. In males, those areas are usually the temples, hair line and vertex. Only hair transplant surgery can fill in areas that are completely void of hair.
