Hair brought back with treatment

If I use the dermaroller and minoxidil without finasteride and get my hair back, will it stick around after I stop the treatment?

Everything you use to keep your hair (minoxidil and dermarolling) must be continued to keep it. The same is true for finasteride. The hair that is brought back, still has its genetic code for apoptosis so if you stop treating it, it will die off.
