Androgenetic alopecia is the leading cause of chronic hair loss in adults. Long considered a taboo subject, particularly for women, it affects millions of people, including world-renowned celebrities.
In recent years, Lady Gaga and Ariana Grande have both publicly discussed their hair loss, thinning hair, and scalp fragility issues.
What is androgenetic alopecia?
Androgenetic alopecia is hormonal and genetic hair loss, linked to the sensitivity of hair follicles to DHT, a hormone derived from testosterone via the 5-alpha-reductase enzyme.
Pathophysiological mechanism
-
DHT binds to follicle receptors
-
It shortens the growth cycle (anagen phase)
-
Hair becomes thinner, shorter, then gradually disappears
-
This is called follicular miniaturization
Why our 4-step protocol is relevant for androgenetic alopecia
A common mistake in hormonal hair loss is treating only the hair fiber or focusing on a single lever.
However, androgenetic alopecia requires a global approach: scalp + follicle + biological signaling + internal action on DHT.
1. Active Anti-Hair Loss Scalp Scrub: exfoliate and purify the scalp
In androgenetic alopecia, the scalp is often:
-
congested,
-
micro-inflamed,
-
laden with oxidized sebum.
Gentle exfoliation allows:
-
to unclog the follicle,
-
to improve oxygenation,
-
to optimize the penetration of anti-hair loss active ingredients.
2. Anti-Hair Loss Shampoo pH 5: cleanse without aggression
An irritated scalp = inflammation = worsening of hair loss.
An anti-hair loss shampoo formulated with a pH close to 5 allows:
-
to preserve the skin barrier,
-
to respect the microbiome,
-
to limit peri-follicular micro-inflammation.
The link between pH, inflammation, and hair loss is well documented (PubMed: Proksch E.).
3. Anti-Hair Loss Serum: acts on the 3 key markers of growth
A truly effective serum for androgenetic alopecia must act on:
-
cell proliferation (e.g. Ki67)
-
growth signaling (β-catenin)
-
follicular growth factors (IGF-1)
The objective:
- reduce hair loss
- prolong the anagen phase
- stimulate higher quality regrowth
These markers are widely used in ex-vivo and clinical studies on hair growth (J Dermatol Sci).
4. DHT Blocker Supplement: acts internally on the hormonal cause
Androgenetic alopecia being hormone-dependent, internal action is essential.
A well-formulated DHT Blocker allows:
-
to partially inhibit 5-alpha-reductase,
-
to reduce the impact of DHT on the follicle,
-
without the undesirable effects of heavy medical treatments.
Numerous publications demonstrate the interest of certain natural active ingredients in DHT modulation (e.g., Serenoa repens, zinc, etc.), even if efficacy strongly depends on dosage and bioavailability, a point often underestimated.
In summary
-
Androgenetic alopecia is a chronic, hormonal, and multifactorial pathology that affects millions of people, including famous individuals.
-
Effective management is based on a comprehensive strategy: scalp, follicle, biological signaling, and internal anti-DHT action.
-
Modern protocols are moving towards natural, microbiome-friendly, and scientifically supported approaches, as a complement or alternative to conventional treatments.
