How do you relieve an irritated scalp?

Uncomfortable dry scalp? Itching? Redness? Tightness?

Just like the skin, the scalp is attacked by external factors that damage its surface layer (the stratum corneum) and cause temporary irritation.

What causes an irritated scalp?

An irritated scalp is a temporary state of crisis.

It is induced by external causes:

  • environmental factors: thermal, chemical or physical aggressions such as pollution, heat, cold, sudden temperature changes, air conditioning, wind, sun, etc.
  • smoking, dandruff, sebum production disorders, frequent helmet wearing...
  • unsuitable and/or aggressive hair products, hot hair dryers...

What are the signs of an irritated scalp?

An aggression toward the scalp results in the inflammation of its stratum corneum.

The irritation then manifests itself as itching, redness and tightness. These discomforts occur temporarily as long as the exposure to the triggering factor continues.

An irritated scalp has many needs

The first thing to do is provide immediate relief to the scalp. This reduces the inflammatory areas, thus calming the irritation and reducing itching.

The irritated scalp also needs to be cleansed and protected from external aggressions to prevent further inflammation.

How to take care of your scalp

There are many natural active ingredients, such as essential oils or plant extracts, that have cooling, anti-inflammatory and antibacterial properties. They promote tissue regeneration for immediate and lasting scalp relief.

Beyond the calming action generated by the application of essential oils, breathing in their fragrance also contributes to this soothing feeling of relaxation.


Cold essential oils, for example, provide a fresh feeling upon application and immediately calm scalp inflammation.

Natural Asteraceae extract, for example, strengthens the scalp's natural defenses on a daily basis and thus reduces its reactivity.

It can be combined with Hamamelis floral water, which possesses the beneficial properties of essential oils combined with a high tolerance. This gentle active ingredient improves the barrier function of the scalp and reduces itching thanks to its anti-inflammatory, soothing, softening and protective properties.

Native Americans relied on the medicinal properties of Hamamelis to treat bleeding and inflammation. Poultices and infusions made from its leaves and bark have long been used medicinally to treat wounds and bleeding, as well as all types of abrasions.


Combining vitamins with these natural active ingredients makes it possible to design highly effective treatments to improve the well-being of an irritated scalp.

Vitamin E is an antioxidant that helps to neutralize the free radicals responsible for aging and weakening the tissues. The scalp is protected from these harmful oxidative effects.

At the same time, linoleic acid is widely present in vitamin F. This essential fatty acid acts as a hydrolipidic barrier and thus protects the scalp against external aggressions, as well as against dehydration.

Vitamin A is involved in the formation of skin and mucous membranes, which is why it plays an important role in the healing process. It also promotes the regeneration of stratum corneum cells.

With a treatment combining these different active ingredients and vitamins, the scalp regains balance and is soothed over the long term. It immediately feels soft and comfortable once again. The hair becomes supple, shiny and easy to style.
