Hi i have been on finasteride and minoxidil for over 30 years under the supervision of Hugh Rushton of harley st and still have a good head of hair dont buy it as a mixed solution as it doesnt work as well he told me lately i was thinking of going down that route.
I mix in a crushed up tablet up tablet of Certrizine in the solution and take a few tablets a day as this medication has been linked to help hair loss and is very cheap. if ur not taking minoxidil you can add to distilled water and apply to the scalp i use a laser cap every other day also.
Gud luck with it as prevention is better than cure as they say
