An ordered, science-based roadmap
One video says one thing, a forum says the opposite, and everyone is selling something. This book puts things in order: it explains what has been shown to work, the order to approach it in according to the science, and what you can rule out. It sells you nothing.
What will you find inside?
1. How androgenetic alopecia works
What DHT is and why your follicles miniaturize.
2. Are you sure it’s AGA?
Other causes of hair loss that get mistaken for it.
3. A phase-by-phase roadmap
From the best-supported treatments to the newest, with what’s known about their effectiveness and side effects.
4. What to expect and when
Realistic timelines for results, so you don’t quit too early or expect miracles.
5. Hair transplant
When it’s considered, what it can and can’t do, and why it doesn’t replace treatment.
6. What’s coming
Drugs in development and what’s actually true about them.
7. Treatments you can rule out
And why.
8. References
Every study cited, with a link.

About the author
I’m Manuel García, and I’ve spent more than eleven years researching androgenetic alopecia. Twelve years ago I started losing hair and several dermatologists wrote my case off, so I decided to analyze the studies myself. My background in statistics has helped me separate information that is true and proven from what only sounds good but has no evidence behind it.
My YouTube channel has more than 148,000 subscribers, and I analyze treatments one by one with the same rule: published studies, cited sources, and rigorous analysis of the evidence, whatever the final conclusions may be.
