We often treat hormonal decline as a hormonal issue, but that's only true initially. DHT triggers the process, but three other mechanisms then come into play and maintain it. Here are the four, and what each one does.

Mechanism #1: the conversion of testosterone into DHT
This is the starting point. 5-alpha-reductase converts testosterone into DHT, and in affected individuals, it's not the amount of hormone that's the issue, but rather the sensitivity of the hair follicle, which is genetically determined. In these sensitive follicles, each cycle produces a hair that is slightly thinner and shorter, until it no longer pierces the surface.
- The density decreases before the fall becomes visible.
- The phenomenon is gradual, never sudden
- This conversion is internal: only one DHT blocker it is affected orally
What I see most often in consultations are people who have blocked the hormone for months without ever addressing the inflammation. They slowed the hair loss, but the follicle continued to shrink silently. Treating one of the four mechanisms only treats a quarter of the problem.
Mechanism #2: Low-grade inflammation of the scalp
A subtle perifolliculitis develops around the miniaturized follicle. It doesn't itch, it doesn't cause redness, it's invisible—and that's precisely what makes it so insidious: it goes untreated because it's undetectable. Over time, it progresses to fibrosis, which irreversibly reduces the diameter of the follicle. Washing plays an underestimated role here, because a shampoo that's too alkaline perpetuates the inflammation we're trying to reduce: it's better to wash with a pH of 5.
Mechanism #3: Follicle obstruction by sebum
DHT also stimulates the sebaceous glands. Excess sebum disrupts the scalp microbiome and the ostium, the opening through which the hair emerges, eventually becomes blocked.
- The bulb receives less oxygen
- Local inflammation is increasing
- The assets applied subsequently no longer cross anything.
This is why exfoliating the scalp is not a comfort step in an anti-hair loss routine, but a prerequisite.
Mechanism #4: The skin barrier that blocks active ingredients
This is the most overlooked mechanism, and the one that explains the most disappointments. The stratum corneum is a barrier designed to prevent substances from penetrating, and it does its job very well: less than 1% of the active ingredients in a conventionally applied serum actually reach the follicle. An excellent serum that is poorly delivered remains ineffective—it's not the formula that's the problem, it's the delivery route. Two approaches allow us to overcome this barrier: clearing the scalp beforehand, and opening a temporary passage, the principle behind micro-infusion where 0,5 mm micro-needles create micro-channels that close spontaneously.

"I had been using minoxidil for years but with many side effects. I tried this
I tried the serum, thinking it wouldn't work... and yet! The bald spot on the back of my head has clearly filled in. Amazing!

Discover the solutionThe protocol that covers the four mechanisms
These four cascades are mutually reinforcing. Blocking hormonal conversion without unclogging the follicle, or stimulating growth without reducing inflammation, is like closing one leak while leaving the other three open.
- Cascade 1, hormonal conversion: an oral DHT blocker, for prolonged use
- Cascade 2, inflammation: a pH 5 shampoo, two washes per week
- Cascade 3, dysbiosis: a scalp scrub, once a week
- Cascade 4, penetration: a serum, ideally delivered by micro-infusion
Androgenetic alopecia is a chronic process: treatment is measured in years, not weeks. The first signs involve a slowing of hair loss and take several months to appear; the increase in density cannot be assessed before six months, often twelve. And the benefit is maintained as long as the protocol is followed—when stopped, the process resumes where it left off. Furthermore, hair loss that worsens significantly in the fall can have two distinct causes.
Hormonal Anti-Hair Loss Protocol
Specifically acts on hormonal hair loss
To remember
- DHT triggers, the other three cascades maintain
- The inflammation is silent and progresses towards irreversible fibrosis.
- Less than 1% of the active ingredients in a typical serum reach the follicle.
- Allow three months, the duration of a hair growth cycle.
