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 is not itchy, it is not visible, and this is precisely what makes it so dangerous: it slowly progresses to fibrosis which irreversibly reduces the diameter of the follicle.
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 Tricho-Force pH5 Anti-Hair Loss Shampoo located?
It addresses the second stage of hair loss. Its pH of 5 respects that of the scalp and preserves the hydrolipidic film, allowing the microbiome to regain its balance and limiting low-grade perifolliculitis. This is an often underestimated point: a shampoo that is too alkaline or sulfate-rich, used several times a week on an already weakened scalp, perpetuates the very inflammation we are trying to reduce. The act of washing is never neutral in hair loss—this is what makes the difference between a suitable natural shampoo and a commercial one.
One shampoo is not enough
To cover the four stages, the shampoo is combined with the three other steps of the hormonal anti-hair loss protocol — or the reactive anti-hair loss protocol depending on the origin of your hair loss:
■ Cascade 1 — DHT Blocker (hormonal drop) or Tricho-Caps 5F (reactive hair loss): 2 capsules per day for 3 months.
■ Cascade ② — Tricho-Force pH5 Anti-Hair Loss Shampoo : this product.
■ Cascade ③ — Active Anti-Hair Loss Scrub Once a week, before shampooing, massage with the stimulating brush.
■ Cascade 5 — Micro-Infusion Pack : 2 to 3 times a week, without rinsing.
Each axis targets a distinct mechanism: the protocol's effectiveness is synergistic, not simply additive. Discover the entire Tricho-Force range.

Dosage
For a more effective cleanse, shampoo twice with each wash. Apply the product, massage it into the scalp with the stimulating brush , then leave it on for 5 minutes before rinsing. Use twice a week.
