Some people are constantly prone to dandruff. Others find their condition worsens at very specific times.
A number of factors can indeed come into play, depending on life stages and your environment.
Here are the factors that promote the appearance of dandruff:
Puberty: this is when hormone levels begin to fluctuate, and the scalp starts to produce more lipid film. The microorganism responsible for dandruff, Malassezia Globosa, breaks down this sebum into other substances that are irritating to the scalp. This explains why dandruff often appears at puberty.

An increase in internal temperature: when your body temperature rises, the microorganism Malassezia Globosa finds itself in ideal conditions for proliferation. This is why, when the skin on your head warms up, for example by wearing a hat, your scalp is subject to an increased risk of irritation, and consequently of dandruff.
Stress: it can weaken your natural defenses and prevent your body from reacting correctly to scalp irritation. And in fact, many people complain about a worsening of their dandruff problem during particularly anxious episodes in their lives.

The environment: multiple ambient factors, pollution and UV rays for example, can weaken the scalp's natural defenses and open the way to dandruff. This explains why, after spending time in the sun or in a noisy urban environment, your dandruff seems to increase. The scalp simply has fewer defenses.
Sensitive skin: unfortunately, you can suddenly become allergic to certain substances that have never caused you a problem. If you have dandruff, it's because your skin is reacting to irritants present on your scalp. Use Head & Shoulders regularly to get rid of these substances, and at the same time, dandruff.
