Sug pls - Minoxidil Betamethazone Valerate or Rogaine liquid

[ditto]

Hi Gents,
I used rogaine foam for six months and still having terrrible shed, so decided to switch to some other form of minoxidil.

My Doctor recommends his own custom blend minoxidil with Betamethazone Valerate

Which one is better to switch Minoxidil Betamethazone Valerate or Regular Rogaine liquid?

Thanks & Regards,
Ditto.
