I am 53 years old. Was about a Noorwood 3 - 3,5 about a year ago. I have been using 1.25 mg finasteride and minoxidil topically for many years, but this has not resulted in any new growth. However, 2.5mm microneedling in conjunction with topical minoxidil / finasteride has been very effective for me for the last 3 months. In addition, I also dripped 5mg Minoxidil (4 drops 5% solution) directly into my mouth every day, which certainly contributed to this success. I treated the entire top of the head with my Dermapen every 2 weeks for about 15 minutes.
Even where I only had thin vellus hair for almost 15 years, terminal hair started to grew again after a few 2.5 mm microneedling treatments with my Dermapen, which has an optical effect and thus I gained about 1 Norwood step in the forehead and corner area the last 3 month.
My other hair on the vertex has also gotten thicker. Microneedling with 2.5mm is painful but has fully paid off!
