How do you soothe a sensitive scalp?

Around 41% of European women report having a sensitive scalp.

Skin sensitivity is an increasingly common condition among the world's population. This heightened reactivity is a reflection of a stressed society living in an increasingly polluted and anxiety-provoking environment.

How to recognize a sensitive scalp

A sensitive scalp can be recognized by the fact that it cannot tolerate anything and becomes uncomfortable.

Its barrier function is impaired and the hydrolipidic film is deficient. The nerve cells are characterized by an excessive reactivity to external elements.

Sensitive scalp: a permanent physiological state

By analogy with sensitive skin syndrome, a sensitive scalp is described as a neurosensory phenomenon. It is characterized by an exacerbated response of the scalp to internal and external stimuli.

These reactions may be amplified by a particular emotional or psychological context.


What causes a sensitive scalp?

A sensitive scalp is particularly fragile. This fragility is the result of excessive stimulation of the nerve cells when faced with a natural deficiency of the hydrolipidic film (HLF).

In fact, the natural protection of the scalp, and of the skin, is normally provided by two elements:

  • the HLF (which includes sebum and sweat)
  • the microbial flora found on the surface of the epidermis.

A sensitive scalp is not a temporary condition. It is an intrinsic and permanent feature of the scalp.

Sensitivity is innate and ultimately without specific cause.

While it has no specific cause, this natural hypersensitivity is however aggravated by various factors:

  • internal factors linked to stress, to the nervous or emotional state...
  • external factors: repeated environmental aggressions (pollution, climatic changes), use of unsuitable hair products or techniques (aggressive care products, hair dryer temperature, etc.).

What are the action mechanisms of sensory perception?

Nerve endings in the dermis and epidermis can be activated by many external stimuli. The processed nerve message is then routed to the central nervous system before emerging in the brain.

A sensitive scalp is the result of these nerve cells being overly receptive to the information transmitted to them. This leads to an unpleasant sensation being perceived on the scalp.


What are the symptoms of a sensitive scalp?

A sensitive scalp is characterized by neurosensory symptoms. There can be a moderate feeling of tightness or warmth, but also a tingling or itching of the scalp. Sometimes there may be some temporary redness.

It then becomes uncomfortable.

We often hear the remark: "My scalp can't tolerate anything! “

All these signs correspond to a natural and permanent sensitivity of the scalp. They can therefore be present chronically.

What are the needs of a sensitive scalp?

To treat a sensitive scalp, the priority is to reduce its reactivity.It is therefore its sensitivity threshold that must be lowered and regulated.


Less reactive, it no longer triggers these excessive sensory reactions.

Once the scalp has been soothed, it must then be protected in a sustainable way.

This means strengthening its natural defenses by repairing its protective barrier function. Better protected, it will be less aggravated by external factors. This new balance will prevent the risk of recurrence.

It's important to opt for high-tolerance products rich in active ingredients selected for their gentleness and calming properties. Your shampoo should cleanse gently and respect the balance of the scalp.

Certain natural extracts soothe and reduce the reactivity of the scalp. They therefore provide immediate comfort. Permanently soothed and protected, the scalp can regain its natural balance. The hair will be soft and shiny.


Sensitive scalp: helpful tips!

Tip 1: Choose hair products without silicones and aggressive ingredients. Pay particular attention to the styling products used.

Tip 2: Space out coloring or bleaching as much as possible, especially if the active ingredients are not plant-based. Opt for plant-based dyes.
