18M, 8 Months on Minoxidil & Finasteride, Considering Dermaroller for Hairline Regrowth

Norwood 2.5 and currently on minoxidil finasteride solution, minoxidil 2.5 tablet, vitamins. I can see some baby hair on the hairline, but very less after 8 months of usage. Can I use dermaroller, is it worth it and I am not confident of my hair growing back, I am 18 and very insecure, life sucks rn. My hair is dry and frizzy and the wind exposes my hairline no matter how much I try to hide it. I had a slightly large forehead since birth but now due to receding it’s worse. Are these baby hairs

regrowth on bald areas is hard if not impossible, where you are diffuse thinning it is easier.
