Hair loss is never caused by a single factor. Five factors are involved—nutritional, vascular, tissue, hormonal, and nervous—and a treatment only works if it addresses them all. Here's what each factor encompasses, and what a supplement can actually provide.

What are the 5 factors of hair loss?
Hair is a direct indicator of overall physiological state. Its quality depends on five factors, the importance of which varies from person to person and depending on the type of hair loss.
- The nutritional factor: sulfur amino acids and cofactors necessary for keratin synthesis
- The vascular factor: the microcirculation that supplies the follicle
- The tissue factor: the quality of the collagen that anchors the hair in the scalp
- The hormonal factor: DHT, the main driver of androgenic alopecia
- The nervous factor: the effect of chronic stress on the hair cycle
A dietary supplement works on the body's internal environment, not on hormones. Zinc and B vitamins play a role, but their hormonal effect remains limited—and I prefer to be clear about that. For an established hormonal imbalance, they are a useful support, not the primary treatment.
How does a supplement affect these factors?
Two sulfur-containing amino acids, methionine and cystine, provide the sulfur necessary for the bonds that structure keratin—the very bonds that give hair its strength. Glycine and vitamin C play a role in collagen synthesis, which anchors the hair. Zinc and biotin complete the formula, and plant extracts support scalp blood flow.
On which falls is a supplement relevant?
Nutritional intake is of real importance in several situations:
- A reactive fallwhere many follicles restart at the same time
- A postpartum fall, outside of the breastfeeding period
- A seasonal autumn fall, to support regrowth
- An unbalanced diet or a restrictive diet
- Hair that grows back thin and brittle, rather than falling out
In the case of an established hormonal decline, the supplement provides support: the action on DHT remains the main lever.

"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!

The hair growth cycle dictates its own schedule. Hair grows approximately 0,2 mm per day: the portion produced during the treatment emerges stronger from the first few weeks, but it takes three months for this to be noticeable. This is why a treatment is measured in months, not weeks, and why it reaches its full potential when combined with topical action—serum, massage, microcirculation.

- The effect of a supplement on hormones remains limited
- A minimum of three months: that's the duration of a hair cycle.
