I am 37 years old and had this balding for 10 years. I started using 1 mg PO finasteride daily 1 ml topical minoxidil twice daily 1 biotin vitamin daily, Saw palmetto shampoo, plus 0.5 mm micro needling at home 2-3 times per week.
I would increase the microneedling needles to 1.25mm and reduce the treatments to once a week. That depth gets to the stem cells that control the growth of the follicles to react to the wounds. You also might consider switching to oral minoxidil. Speak with your doctor. The photos suggest that the stem cells are still there and alive, so push the depth of the microneedling t where the stem cell reside.
