I am 23 years old, I lost 90% of my eyebrow hair during 2022-2023 due to stress. my eyebrow hair was almost completely gone, only small patches remained, mostly light. in the summer of 2024 (in July) I started using Regaine 5% foam with a cotton swab on my eyebrows, and after 2 months I had gorgeous, thick dark eyebrows (lots of terminal hair). Strict discipline was maintained for 6 months, but in December 2024 I experienced severe stress again, and also stopped using minoxidil for about a week (because I forgot to take the foam with me). By March 2025, thinning of eyebrows was noticeable, especially noticeable in May 2025, and did not get better by August 2025. Here are the notes I noted that could affect health: 

* In February 2025, zinc, copper and ferritin were below normal. 
* On March 17, 2025, I got the Gardasil vaccine (for 4 types of HPV), on May 17, 2025 I got the second dose. 
* In June 2025, there was a lot of stress, like when I lost my hair in 2022-2023. 
* In July 2025, there was a 10-day break in taking minoxidil due to surgery. 
* Now sex hormones are normal, thyroid hormones are normal, general blood test is normal, but ferritin is low (and I think copper and zinc too). 
* In recent days, I have been very actively using minoxidil, but my eyebrows are falling out and thinning and do not become lush again.

How make minox great again? Are there any scientific / practically viable notes on how to make mnox as efficient as it was when I was 6 months in? I need to restore my Nov/Dec-2024 eyebrow volume :(

Minoxidil stopped working after 12 months?
