SHAMPOO - what it the science behind the ingredients... Part 1
BLACK CUMIN SEED OIL
The active compound here is thymoquinone — a potent anti-inflammatory and antioxidant.
But the part that matters for thinning hair is enzymatic. Studies suggest thymoquinone can inhibit 5-alpha reductase, the enzyme that converts testosterone into DHT.
That's upstream thinking. Instead of trying to block DHT after it's made, you're interfering with the conversion itself — at the scalp, where genetically sensitive follicles are being miniaturized.
Anti-inflammatory on top of that matters too. An inflamed scalp is not an environment where follicles do their best work.
PUMPKIN SEED OIL
One of the most studied natural DHT blockers we have.
A clinical trial published in Evidence-Based Complementary and Alternative Medicine found significant improvement in hair count after 24 weeks of use.
Note that number. Twenty-four weeks.
That's the part nobody wants to hear, and it's the part I insist on saying out loud. Hair runs on a months-long cycle. Nothing you apply to your scalp produces a visible answer in three weeks — not this, not anything.
If a product promises you results by next month, it's selling you a timeline your biology can't honor.
KETOCONAZOLE
This one started life as an antifungal — and that's still useful, because scalp fungal overgrowth is a real and under-recognized driver of irritation.
But it earned its place in hair formulations for a second reason: well-documented DHT-blocking properties at the scalp level, plus a reduction in scalp inflammation.
Inflammation is the piece most people skip past. A chronically irritated scalp is a hostile environment for a follicle that's already struggling.
You can't rebuild on inflamed ground.
