40 year old with hairline regrowth (photos)

This 40-year-old male reversed his hairline recession with minoxidil 6%, 0.3% finasteride topical solution as well as microneedling.  I suspect that without the microneedling, he would have had no response.  Microneedling is a fantastic treatment for almost any age man with balding. The problem with microneedling is “Will it last” and if so, how long without continuing the process.
