If someone want to decrease hairloss and drag away being bald than I think mincroneedling is ok for that at the beggining of hairloss simply because You just doing once a week or once every two week microneedling session so thats more convinent than putting everyday lotion with minoxidil. Also I would add ketoconazole 2% shampoo and/or some shampoo with caffeine. Maybe for someone it would be enough to delay occurance of baldness and heavy hairloss, but keep in mind that sooner or later you will need antiandrogen (finasteride) so why not sooner than later?
