OUR DERMATOLOGISTS ANSWERS

3 QUESTIONS TO OUR DERMATOLOGISTS

why is dandruff coming back?

We regularly see patients in consultation for chronic dandruff condition.
Dandruff is a common condition that tends to come back because of individual predisposing factors such as unbalanced microbiome and sebum.

can dandruff relapse be prevented?

Dandruff condition cannot be cured and is usually triggered by stress or emotional factors. However, relapses can be prevented using a maintenance routine with anti-dandruff shampoos.

How can we treat dandruff condition?

To treat dandruff condition, I recommend to use an anti-dandruff shampoo, 2 to 3 times a week. Then to prevent relapse, I recommend to use the anti-dandruff shampoo once a week in alternance with a soft shampoo.

discover the science on dandruff

What is dandruff?

Dandruff is a biological phenomenon appearing with the unbalance of 3 actors.

dandruff relapse phenomenon

What is sebum?

Sebum is an oily substance produced by the sebaceous glands.
It accumulates in the follicular canal before being discharged onto the scalp.
Like a sponge, the stratum corneum of the scalp absorbs a significant amount of sebum.
Flakes covering dandruff scalps are true 'sebum traps'.

Sebum composition unbalance

This nutrient is eaten by yeast and bacteria. Most Malassezia yeasts are in vital need of lipids to develop themselves that’s why they feed with the triglycerides present on scalp.
Once absorbed, they secrete enzymes that transforms triglycerides into fatty acids. This phenomenon is called squelene peroxidation which will then induce inflammations.

What is microbiome?

The microbiome is the invisible ecosystem of living microorganisms which is integral part of your skin’s surface. Its balance is essential to your skin health.

Each square centimeter hosts from 10000 to 1 hundred million inhabitants. The resident flora is made of 2 bacterial populations:

core bacteria species
(Proprioni bacteria & staphylococci)

yeast
(Malassezia)

Microbiome unbalance

When dandruff occurs, Malassezia Restricta multiplies per 10 and unbalances microorganisms population.

* Double blind randomized study, under dermatological control on 56 volunteers with moderate to severe dandruff. 3 shampoos/week during 4 weeks after 3 weeks of wash out. 4 weeks of remanence without treatment. 25 used the Dercos anti dandruff shampoo and 31 used the vehicle shampoo. Measure done by QPCP (on lesional and non lesional zones)

What is the scalp barrier?

The stratum corneum is the most superficial layer of the skin.
It forms a barrier that :

  • What is the scalp barrier? - protects the scalp against aggressions
  • What is the scalp barrier? - contributes to maintain scalp’s level of hydration.

When the barrier function is altered, dandruff & scalp seborrheic dermatitis appear.

Scalp barrier unbalance

The barrier function is composed of corneocytes, locked together by an intercellular matrix composed of lipids. When the barrier function is altered, this intercellular cement is disorganized and the corneocytes detachment process is disrupted.

The altered barrier becomes more permeable to microbial agents, external agents and other irritating components. It induces inflammation which further disrupts the skin barrier. This is then a vicious circle that creates scalp inflammation.
