Also fidia will need to beat the completely bad reputation on hair loss products all the snake oils made. If it would be overpriced a lot of people would be like. Meh, probably scam. Underpriced - Meh, for that price it cant do any good. People are idiots as buying power

.
Of course other pharmacies cant exactly copy it. However, they can find out the mechanism and make other substances with same or better results. Pharmacies do it a lot. Sometimes you dont even have to change it so much. Like here on gourmetstylewellness.com is quite popular certizine. It was developed by UCB as Zyrtec. You know how they increased its effectivity? They changed the rotation of certizine molecule to the left and levocetirizine (Xyzal) was made. (I am not a chemist etc. I just worked there.) Even though it was just different rotation of the same molecule they had to patent it again. So If they overprice it I believe, that other pharmacies would feel a chance there.
What is bigger question for me is... How they gonna solve the US market? FDA won´t let them just enter it and I doubt they would deny that strong buying power.
