Here's my concern:
If Jacare is opting for the big 3 (minoxidil + finasteride + ketoconazole), then he's being duped by a snake oil salesman. He currently sits at Norwood 7 (almost completely bald) with most of his follicles dead. None of the DHT blockers would do shit to revive those follicles, not to mention messing around with testosterone will negatively impact his performance, and possibly make him test positive.
If he's opting for a hair transplant, he might be out of commission for 8+ months while he waits for his scars to heal and hair to regrow, or he'll have to show up looking like this
And given his advanced stage of hair loss, much of his traditional donor area would have already been breached at this point, and he might require multiple transplant surgeries, which would put his career on hold even longer, with no guaranteed good results.
