Will microneedling need a boost?

Hello Doc hope you are well. Just wanted to get your take on something. I’ve been taking finasteride for about 2 years with decent results , mostly maintenance. However I’ve seen considerable progress microneedling my scalp. I’ve been doing it for a over a year and it is still yielding positive results. I would attribute most of my regrowth to microneedling in fact. Since this is a natural treatment I was wondering what your thoughts were in regards to the possible longevity of this treatment. If I’m happy with where I’m at , could say a microneedling routine once a month maintain these results? Love to get your thoughts on this. Take care.

I know a little bit about the research done when injuries like microneedling induces hair growth. These hairs may need to be ‘kicked’ with another short course of microneedling, possibly every 6 months. We are not clear what will happen to the hair follicle when it goes into telogen (rest) cycle and then must come out of it into Anagen (growth) for the new hair to develop. I believe some ‘kick’ should occur periodically and I am guessing about every 6 months or so. We are learning more as we go forward.
