SEBORRHEIC DERMATITIS
Seborrheic dermatitis of the scalp: it's not just dandruff
La seborrheic dermatitis of the scalp is often confused with simple dandruff.
It is actually a more complex condition, characterised by inflammation, sebum alteration and skin instability.
It is not just an aesthetic problem.
It is a sign that the scalp has lost its balance.
“Seborrhoeic dermatitis is not falling skin. It is a system that no longer regulates itself.”
Symptoms of seborrheic dermatitis
The most common signs are:
-
persistent desquamation (often yellowish and greasy)
-
oily skin
-
hair that gets dirty quickly
In some cases they may be associated:
-
irritation
-
burning
-
increased hair loss
What really happens to the skin
Alteration of the skin microenvironment
The scalp is a complex ecosystem.
It includes sebum, microbiota, skin barrier and continuously renewing cells.
In seborrhoeic dermatitis, this balance is disturbed.
A combination of factors occurs:
-
excessive sebum production
-
sebum of altered quality
-
microbial proliferation
-
inflammatory response
The result is an unstable skin, alternating between improving and worsening phases.
The role of sebum
Sebum is not the problem.
The problem is when the composition changes.
Altered sebum can:
-
irritate the skin
-
promote desquamation
-
create an inflammatory environment
-
alter the microbiota
For this reason, eliminating sebum does not work.
It needs to be rebalanced.
Causes of seborrheic dermatitis
The causes are not unique.
Often several factors are involved.
Internal factors
-
prolonged stress
-
disordered feeding
-
metabolic imbalances
-
intestinal alterations
-
hormonal changes
External factors
-
aggressive shampoos
-
too frequent washing
-
chemical treatments
-
pollution
Seborrhoeic dermatitis is often the result of an overloaded system.
Seborrhoeic dermatitis and stress
Stress plays a central role.
It can:
-
increase sebum production
-
amplify inflammation
-
make the skin more sensitive
It is not uncommon to see worsening in the most intense periods of life.
Seborrhoeic dermatitis and hair loss
Seborrhoeic dermatitis does not directly cause hair loss.
But it can create an unfavourable environment for the follicle.
When the inflammation persists:
-
the hair cycle may alter
-
hair becomes more brittle
-
the fall may increase
The most common mistake: only treating the surface
Many interventions focus on:
-
anti-dandruff shampoo
-
degreasing products
-
quick solutions
The result is often temporary.
Why?
Because you intervene on the symptom, not the cause.
When an in-depth medical examination is necessary
If it is persistent, extensive or associated with obvious lesions, a specialist consultation is important.
Professional skin management can accompany the course, but not replace it in more complex cases.
How to manage seborrhoeic dermatitis effectively
A correct approach involves:
-
Gentle and functional cleansing
-
Rebalancing sebum
-
Reduction of inflammation
-
Constancy in management
-
Attention to lifestyle
There are no immediate solutions.
There is a path.
A signal to listen
La seborrheic dermatitis is an indicator.
Talk about:
-
skin balance
-
inflammatory state
-
sebum quality
-
internal conditions
To ignore it is to postpone the problem.
“The skin doesn't get worse all of a sudden. It gets there step by step.”
It is not a mere nuisance.
It is a condition that requires understanding, not aggression.
Only by working on the causes can the skin be stabilised over time.
Contacting a qualified professional is always the best choice when dealing with concerns related to the health of your skin and hair. Whether you are uncertain about the nature of any abnormalities or simply want confirmation, an expert can make all the difference. A timely and accurate diagnosis is a crucial step for the well-being of your skin and hair, providing you with peace of mind and an appropriate treatment plan.
