When I start propecia my hair was thick , does its return to be thick because i start the treatment early ?

Thank you for posting your question. Typically when patients first start using Minoxidil 5% they see an increase in shedding because it pushes the cycle of the hair from shedding back to the growing phase. This takes several months to see a difference in density, typically 4 to 6 months. When Minoxidil use has been stopped, patients only experience shedding of hairs it helped to grow. Minoxidil and Finasteride use should be indefinitely for best outcome, if no side-effects are reported. 

Effects of both minoxidil and finasteride depends on how long you use them properly .İf you stop to use them than the effects will gone away in couple of months.
