Hair loss is a common phenomenon affecting both women and men, and can have many causes. It manifests as a progressive loss of density, a thinning of the hair fiber, or visible baldness in certain areas (part, temples, crown of the head, etc.).
The most common causes are:
■ Hormonal hair loss : linked to a genetic sensitivity to androgen hormones — female androgenetic alopecia or male pattern baldness — at menopause or in the case of polycystic ovary syndrome (PCOS).
■ Reactive hair loss : stress, fatigue, change of season, nutritional deficiencies, infections, hormonal variations, especially postpartum.
When hair loss is hormonal, it is not based on one mechanism, but on four.
Androgenetic alopecia affects one in two men by age 50 and 40% of women after menopause. It is triggered by a cascade of four self-sustaining processes — which is why a single product always reaches its limit.
① Hormonal conversion. Under the action of 5-alpha-reductase, testosterone is converted into DHT. In genetically sensitive follicles, this hormone shortens the growth phase: the hair grows back thinner, shorter, until it stops growing altogether. This is follicular miniaturization.
② Low-grade inflammation. A subtle perifolliculitis develops around the follicle. It doesn't itch, it's invisible, and that's precisely what makes it so dangerous: it slowly progresses to fibrosis, which irreversibly reduces the diameter of the follicle. This is also why using a pH 5 shampoo is not just a matter of comfort.
3. Dysbiosis and follicular blockage. Excess sebum disrupts the scalp's microbiome. The ostium—the opening through which the hair emerges—becomes blocked, depriving the bulb of oxygen and amplifying inflammation. Exfoliating the scalp remains the most underestimated step in an anti-hair loss routine.
④ The skin barrier. The final, and most underestimated, barrier: less than 1% of the active ingredients in a conventionally applied serum penetrate the stratum corneum to reach the follicle. An excellent serum that is poorly delivered remains ineffective.
Where is the Micro-Infusion Pack located?
It addresses the fourth cascade. 0,5 mm microneedles create temporary microchannels, which close spontaneously within 2 to 72 hours, thus increasing the penetration of active ingredients to the hair follicle. The mechanical stimulation itself activates the Wnt/beta-catenin pathway and the local production of VEGF, two signals that promote follicle regrowth. This is something that simple manual application cannot achieve. This is also what makes it a relevant procedure in post-transplant care.
One product alone is not enough
To cover the four cascades, micro-infusion is combined with the three other steps of the hormonal anti-hair loss protocol :
■ Cascade 1 — DHT Blocker : 2 capsules per day for 3 months.
■ Cascade 5 — Tricho-Force pH5 Anti-Hair Loss Shampoo : two shampoos at each wash, twice a week.
■ Cascade ③ — Active Anti-Hair Loss Scrub Once a week, before shampooing, massage with the stimulating brush.
■ Cascade ④ — Micro-Infusion Pack : this product.
Each axis targets a distinct mechanism: the protocol's effectiveness is synergistic, not simply additive. Discover the entire Tricho-Force range.

Dosage
■ In case of moderate fall : apply the serum 2-3 times a week on a clean, dry scalp.
■ In case of aggravated fall : apply the serum everyday until visible improvement.
This Micro-Infusion Pack has been formulated from powerful natural active ingredients and benefits from very good tolerance, including with prolonged daily use.
Precautions for use
Wash your hands thoroughly before applying the micro-infusion. For adult use only. External use only. Avoid contact with eyes. If irritation occurs, discontinue use immediately.
