Is shift from Minoxidil 5% to Capixyl [Grocapix ] advisable for treatment of MPB Hairfall. Can I expect better results?

After 18-20 months of Minoxidil,Finasteride use,I couldn't notice significant regrowth,but hair fall has certainly been checked to minimum.An experienced dermatologist has recently advised me to replace Minoxidil with Grocapix solution [Capixyl].He suggested to combine them for 2 months & completely switch to Grocapix later [Finasteride will continue] 1.Will the Minoxidil withdrawal hair-loss be checked by Grocapix [Capixyl] ? 2.Is the above suggested treatment effective in long-run ?
