hair loss products

This is a product my nephew was prescribed when he received treatment at a university hospital for severe hair loss caused by the side effects of the COVID-19 vaccine.

My brother-in-law consistently applied the leftovers to his eyebrows, and they became darker.

I used to wear my hair in a bun a lot when I was younger, so the hair at the front is getting particularly thin. I bought this at a pharmacy and have been applying it, but I haven't been able to use it consistently, so I don't know if it's working yet.
