Scalp Irritations: What are the Causes?
The scalp is a sensitive area of the body that can sometimes be prone to irritations. These manifest themselves through the appearance of redness, sometimes taking the form of patches of varying thickness and accompanied by itching. Biologically, an irritation is the result of an inflammatory response of the body following an external aggression. Here are the main causes of scalp irritation:
A genetic predisposition.
Some individuals have a compromised skin barrier that no longer fulfills its protective function. This is referred to as atopic skin or scalp. Studies have highlighted a link between atopy and a modification of the gene coding for filaggrin, a protein essential to the integrity of the stratum corneum. People with an atopic scalp are thus less protected from external factors (sun, pollution, certain surfactants present in shampoos...) and are more prone to irritations.
An allergy.
Scalp irritations can also be due to an allergy to a specific compound to which the individual has been exposed. This could, for instance, be a molecule found in clothing, a cosmetic product, a medication, or encountered in their workplace. In response to contact with this allergen, the person's immune system mobilizes certain pro-inflammatory cytokines and causes inflammation in the area.
Exposure to the sun.
The sun has a drying effect on the skin and the scalp , and it alters the hydrolipidic film present on their surface. This film's purpose is to protect the epidermis from external aggressions and to limit its dehydration. When the hydrolipidic film is weakened, the scalp is more prone to irritations.
The wearing of beanies or motorcycle helmets.
Repeated friction from a hat or motorcycle helmet can irritate the scalp. Indeed, these accessories create a warm environment conducive to perspiration. This can cause tingling sensations and irritations. This is largely due to the natural acidity of sweat, which has a pH between 4 and 6. Additionally, it contains sodium chloride, or salt, which has a drying effect. However, skin dryness itself is a cause of scalp irritation.
Advice #1: Opt for a gentle shampoo.
To combat scalp irritations, we recommend opting for a very gentle shampoo, formulated without irritating surfactants or sulfates. Moreover, shampoos intended for sensitive scalps often contain soothing active ingredients such as bisabolol or allantoin. These products thus have a dual effectiveness and cleanse the scalp while providing relief.
Furthermore, we recommend that you do not wash your hair every day. Indeed, this could disrupt the hydrolipidic film of the scalp and increase the risk of irritation. Shampooing every two to three days is sufficient.
Advice #2: Use a soothing and moisturizing treatment.
There exist certain soothing and hydrating cosmetic treatments designed for the scalp. These often come in the form of serums, which are easy to apply and have a light texture so as not to make the scalp oily. Soothing and hydrating treatments help to alleviate various types of discomfort, such as dryness, itching, or redness.
Advice : Don't wait until your scalp is highly irritated before applying a moisturizing treatment. For quick relief, we recommend regularly moisturizing your scalp.
Advice #3: Massage the scalp with essential oils.
To soothe scalp irritations, it is also recommended to massage it with essential oils that have soothing and anti-inflammatory properties. Usually, a few drops are enough to calm the scalp. Don't hesitate to massage to help the treatment penetrate. Among the most renowned essential oils for relieving irritations, we find thetea tree essential oil (INCI: Melaleuca Alternifolia Leaf Oil), thetrue lavender essential oil (INCI: Lavendula Angustifolia Oil) and therosemary essential oil (INCI: Rosmarinus Officinalis Leaf Oil).
Advice #4: Apply cold.
Cold is an excellent ally in the case of irritations and itching. Indeed, it has soothing properties and can help to alleviate an irritated scalp. To do this, apply a cold water compress to your scalp for about fifteen minutes. You can also use ice cubes wrapped in a clean cloth. However, be careful not to apply the ice cubes directly to your scalp, as this could further irritate it.
