Here’s what finally made it all click for me.
I often ask my patients to picture their hair follicles like a garden hose.
When we’re younger, blood flow, oxygen, and nutrients move freely...
helping hair grow thick, strong, and healthy.
But for many women after 40, hormonal shifts can begin changing that environment.
One hormone in particular, DHT, has been linked to thinning hair.
Over time, it may begin affecting how well follicles are supported — like a kink forming in a garden hose.
Less nourishment. Less support.
And gradually, hair may begin feeling thinner, weaker, or easier to shed.
This is often when women notice a widening part, more visible scalp, or a ponytail that suddenly feels smaller.
But here’s the encouraging part:
Many follicles aren’t actually gone — they’re simply dormant.
In many cases, the issue isn’t that hair can no longer grow.
It’s that the scalp environment has changed.
