Two years ago, I was reviewing hormone panels from my patients when I noticed something disturbing.
Every single woman over 40 who came to me with sudden hair loss had one thing in common:
Their estrogen levels had dropped.
Now, you might be thinking: "Of course, that's menopause. Everyone knows this."
But here's what nobody was telling these women…
When Estrogen Drops, DHT Takes Over
For most of your life, estrogen acts like a protective shield for your hair follicles.
It keeps them strong, healthy, and growing.
But when you hit your 40s and estrogen starts declining, whether from perimenopause, menopause, or natural aging, something dangerous happens:
A hormone called DHT floods your scalp.
DHT (dihydrotestosterone) is like kryptonite for your hair follicles.
It literally shrinks them, choking off their blood supply and forcing them into early retirement.
This is why you're suddenly losing hair in your 40s when you've had thick hair your entire life.
It's not genetics. It's not stress. It's not your shampoo.
It's low estrogen allowing DHT to attack your follicles.
