Finasteride, minoxidil, dutasteride, microneedling with PRP all had zero effect - where do I go from here?

Top of my scalp started thinning at 17. I was on oral finasteride and topical minoxidil for 4 years, along with 5 sessions of microneedling with PRP. It had no effect at all, positive or negative. Hair loss continued until I had to start shaving my head, so I stopped all medication. I also tried six months of dutasteride which did nothing. Last year my dermatologist recommended oral minoxidil, which also hasn’t had an effect.

What else can I do at this point? I’m looking into laser diode caps but I’m not certain if they’re a scam or not.
