Should I try medications before having a hair transplant?

I got scheduled for a hair transplant in 8 weeks and prescribed oral minoxidil at the same time (was already on fin). Should I wait to see how the oral min goes before the transplant?

I always like to see the my patients try all of the available medications before I would do a hair transplant on them. Sometimes I am very surprised with the results. The frontal hairlines are usually unresponsive to these medications if your hairline loss is over 5 years old and you are over 25.
