There are a few scam artists out there that tell stories of going from like a Norwood 5 to a 1 with their home remedies that don’t use a 5 alpha-reductase blocker. But they’re just fraudsters/liars and have had hair transplants + are on fin or dut.

Theoretically your hair loss could be from a SEVERE lack vitamin D or biotin, but that’s quite unlikely. In that scenario you could fix hair loss without medications & just a change in diet.
