Dandruff, a common condition of the scalp.
In France, dandruff affects 1 in 2 people. Despite being harmless, dandruff can tarnish the daily lives of those affected, as it is unsightly and causes varying degrees of itching.
Easily recognizable, it is dead cells or scales that are whitish or grayish on the scalp. These dead cells are the result of a rapid cellular renewal at the scalp level. This too rapid cellular renewal causes a defect in the maturation of the epidermal cells, which cannot naturally eliminate themselves. They clump together, thus forming dandruff. Generally, dandruff appears from puberty onwards.
Although the mechanism of accelerated cell renewal causing dandruff is well understood, theorigin of dandruff remains a topic of debate. Indeed, the proliferation of microorganisms (Malassezia fungus), genetic predisposition, and excess sebum are the main causes identified. However, there are other factors that promote the appearance of dandruff (diet, moments of stress...).
The two types of dandruff.
There are two different types of dandruff:
Dry Dandruff:
Thedry dandruffrepresents the most common type of dandruff.Thin,dryand of awhitish color, theyfall like snowonto the shoulders.
Generally, dry dandruff is primarily observed on dry or normal scalps. This type of scalp is characterized by a lack of substances that help keep skin cells together (ceramides, fatty acids, cholesterol). As a result, the skin's barrier function is compromised. This leads to an insensible loss of water at the scalp level.
This dryness leads to a phenomenon of desquamation with the appearance of dry flakes on the scalp. Due to a lack of sebum, these flakes do not adhere to the scalp and fall like snow.
Oily dandruff:
Oily dandruff is observed on oily scalps. Indeed, these appear due to an excess of sebum, which is a factor promoting dandruff. Moreover, sebum is a nutritious environment conducive to the proliferation of Malassezia type fungi, responsible for dandruff.
Unlike dry dandruff, which does not stick to the scalp, oily dandruff remains adhered to it. Moreover, it tends to itch more than dry dandruff.
Although they are harmless, dandruff can impair the quality of life of those affected due to itching and the "neglected" appearance they reflect. Moreover, it can be particularly challenging to eliminate. Certain actions can help reduce their occurrence.
What can be done to eliminate dandruff?
Generally, flaky skin conditions are chronic, meaning they tend to recur. To limit the number and frequency of these recurrences, certain good practices need to be adopted:
Space out your shampooing sessions.
When one has dandruff, the initial instinct is to wash the hair daily to get rid of visible flakes, but this is a mistake! Frequent hair washing leads to a heightened sensitivity of the hydrolipidic film and triggers an overproduction of sebum in response. These two outcomes are factors that promote the appearance of dandruff.
Try tospace out your shampoos as much as possible (a maximum of 3 times per week) in order to maintain the health of your scalp and to avoid creating an environment conducive to the development of dandruff.
The use of a suitable gentle shampoo.
If you have dandruff, the choice of shampoo is of utmost importance. Indeed, it is necessary to avoid shampoos containing harsh surfactants (Ammonium Lauryl Sulfate, Sodium Lauryl Sulfate, Sodium Laureth Sulfate), as these are irritating to your scalp and therefore exacerbate the dandruff condition. Instead, favor shampoos with gentle surfactants (Lauryl Glucoside, Sodium Lauroyl Sarcosinate...)
Furthermore, depending on the type of dandruff, the anti-dandruff agents vary. For example, for oily dandruff, we will find sebum-regulating agents (zinc, nettle extract) and keratolytic agents (salicylic acid, lactic acid). For dry dandruff, the moisturizing agents (glycerin, aloe vera...) are particularly recommended.
Some active ingredients are common to both types of dandruff such as the antifungal agents (piroctone olamine), the anti-proliferative agents or even the soothing agents that alleviate itching.
Note : There are dandruff shampoos suitable for both types of dandruff.
Opt for cold water!
Hot water irritates the scalp and stimulates the sebaceous glands. Therefore, when you wash your hair, it is preferable to use cold water, which will also help to soothe itching and feelings of discomfort.
Note : Just like hot water, heating devices should be avoided in case of dandruff. If you dry your hair with a hairdryer, set it to the lowest temperature.
Avoid wearing hair accessories (hats, caps, headbands).
When dealing with dandruff, it can be tempting to wear hair accessories to conceal it. However, these accessories can cause sweating and overstimulate the sebaceous glands. As a result, the scalp becomes oily more quickly, promoting the growth of the microorganisms that cause dandruff. Therefore, it is best to avoid wearing hats, caps, or headbands as much as possible.
Typology products for getting rid of dandruff permanently.

In addition, this treatment contains essential oils of Atlas cedar and clary sage known for their anti-dandruff and sebum-regulating actions.
