Dandruff appears when the natural cycle of scalp cell renewal speeds up. Normally, this process is invisible. But when it is disrupted, dead skin cells accumulate and become visible as flakes.

This imbalance can be triggered by several factors. Excess sebum creates an environment that encourages the growth of microorganisms, particularly yeasts that are naturally present on the scalp. On the other hand, a scalp that is too dry or irritated can also react by flaking.

Other factors can worsen the condition, such as the use of overly harsh hair products, hard water, stress, fatigue, or hormonal changes. In all cases, dandruff is a sign of a scalp that is no longer functioning optimally.

There are two main types of dandruff, each linked to different causes.

Dry dandruff is fine, white, and lightweight. It flakes off easily and falls onto the shoulders. It is usually associated with a dry, sensitive, or irritated scalp, often caused by unsuitable haircare products. This type of dandruff is often accompanied by tightness or discomfort.

Oily dandruff, on the other hand, is thicker, yellowish, and sticks to the scalp. It is caused by excess sebum combined with the proliferation of a microscopic yeast. This imbalance can lead to itching, inflammation, and a scalp that becomes greasy again quickly. It is the most persistent and hardest type of dandruff to eliminate.

Identifying the type of dandruff is essential to adopting the right routine.

One of the main reasons dandruff persists is that many products only treat the visible symptoms. They temporarily remove flakes without addressing the root cause of the imbalance.

When the scalp remains disrupted, due to excess sebum, an imbalanced microbiome, or irritation, dandruff eventually returns. This can create the feeling that nothing works in the long term.

To achieve lasting results, it’s essential to adopt a holistic approach that targets both visible dandruff and the scalp’s underlying environment.

Dandruff rarely comes alone. It is often accompanied by itching, sometimes intense, due to scalp irritation.

You may also experience discomfort, tightness, or a sensitized scalp. In the case of oily dandruff, the roots may become greasy more quickly, making the hair feel heavy or look “dirty” soon after washing.

These signs are important indicators of a scalp imbalance and should not be ignored.

Eliminating dandruff sustainably is not just about making flakes disappear. It’s essential to address the root cause.

This involves several complementary actions: regulating sebum production, limiting the proliferation of responsible microorganisms, soothing irritation, and restoring the scalp’s natural balance.

Using targeted, non-aggressive care helps not only reduce visible dandruff but also prevent it from coming back. This holistic approach is key to achieving long-lasting results and maintaining a healthy scalp.
