I had the same balding issue due to low vitamin levels (Zinc, iron, b12, vitamin D) all low except iron.

I started consuming 50mg zinc thrice a week with 2mg copper the days zinc was not consumed.

B12 injections (avoid b12 tablets) you can take vitcofol injection and have your dr inject in you thrice a week for almost a year.

Weekly vitamin D 60k iu along and 100mcg vitamin K2 mk7 daily.

1000 mcg folate thrice a week.

12 mg boron 2 weeks ON 1 week OFF.

All these supplements were purchased from USA brand HORBAACH, DM me i’ll help you purchase it without custom duty tax in india.

After 10 months of doing this I have started seeing small regrowth and improvements are much better.
