He explained it to me like I was five years old. And honestly? That's what I needed.
"There's a 2014 clinical trial," he said. "Randomized, double-blind, placebo-controlled — the GOLD standard. 476 women, 2000mg of pumpkin seed oil daily or a placebo, 24 weeks."
"The pumpkin seed oil group grew measurably more hair than the placebo group. Higher self-rated improvement. Higher satisfaction scores."
I did the math in my head.
"So if my bottle had 180mg, I've basically been taking what? 20% of the studied dose?"
"Essentially, yes," he said.
Then he explained the part I didn't expect.
"Pumpkin seed oil only does half the job," he said. "It helps limit how much DHT your body makes in the first place.
The other half is stopping the DHT that's already there from reaching the follicle at all. That's saw palmetto's job. Most bottles skip it completely."
"Here's the simplest way I can put it," he said.
"Your follicles have had a bodyguard your whole adult life."
"Her name is estrogen."
"She's kept a troublemaker named DHT away from the door."
"After 40, she starts leaving early. A little more, every year."
"By 50, she's barely around. DHT does whatever it wants."
"You already know this pattern from somewhere else in your body," he said.
"It's the same reason hot flashes seem to come out of nowhere as estrogen drops — your internal thermostat losing its grip.
Your follicles are going through something similar. Just slower, and quieter, so it's easier to miss."
Then he gave me the timeline, plainly, so I'd stop guessing.
Weeks 1 to 4: shedding starts to slow.
Months 2 to 3: the hair you have feels thicker.
Months 4 to 6: fine new growth starts to show.
"Nothing overnight," he said. "Anyone promising that is lying to you."
