What Causes Dandruff?

We all shed our skin. In fact, humans shed their entire outer layer of skin every 2-4 weeks. But dandruff occurs when the skin on our scalp builds up. Most of the time dandruff clusters along the top of the head, behind the ears and at the nape of the neck. There are various known triggers, so if you are dealing with unwanted dandruff then it could be down to any of the following causes:


Most cases of dandruff can be traced to a single-celled bacteria that exists on all scalps called malassezia. It feeds on the oils and produces oleic, which can lead to irritation, redness and dandruff flakes.


This can lead to a condition known as dermatitis (a general term for skin irritation) and dandruff. It’s important to wash hair with dandruff regularly to dislodge the flakes, but you need to ensure you’re using the right products.

When the colder temperatures hit, there tends to be less moisture in the air both outside and inside where central heating can dehydrate the skin. This dryness can trigger a dandruff flare-up.


While stress can’t cause dandruff to start, it can cause dandruff to worsen. The same goes for external aggressors like pollution—city dweller, take note.

A concern some have, is can dandruff cause hair loss? And, in short, the answer is no. However, if your scalp is irritated enough for you to itch it a lot, you could damage the scalp. If your main concern is hair fall, we recommend our Genesis Collection.


If, by now, you have realized you have dandruff you might be wondering - will dandruff go away on its own? ​Unfortunately, it won’t, you need to look at using products specially formulated with dandruff and sensitive scalp in mind.​

The skin on our scalp is similar to the skin elsewhere on our body and when skin is dry it is absent in oil. On the scalp this will lead to a feeling of tightness, itching and a lack of oils, so the roots won’t really ever look greasy. You may see fine white flakes (unlike the bigger clusters you get with dandruff). Dry skin is a type you are born with, however there are some factors than can cause your scalp to become excessively dry:

Kérastase What Causes Dry Scalp


During the perimenopause a drop in estrogen can cause scalp itching, while during menopause you could experience a dry scalp and brittle hair.


Any medications known to dry out the skin will also cause a dry scalp. These include diuretics, antihistamines, acne medications (roaccutane) and cholesterol medications (statins). Of course, if your doctor prescribes medication it’s best to follow their advice but knowing these medications can have the side effect of causing a dry scalp means you can get ahead of it with the right scalp products.

What Products Can I Use if I Have A Dry Scalp?

With a dry scalp, the main aim is to rehydrate the skin and add much needed nourishment, since your scalp is likely lacking in water and oils.

Bain Régénérant Shampoo is a revitalizing shampoo that fights the signs of aging scalp & hair. Reveals stronger, nourished and moisturized hair.

Masque Intense Régénérant Hair Mask is a revitalizing and nourishing masque for moisture and softness and beautiful shine.

An exfoliating treatment like Scrub Apaisant is ideal for sensitive and dry scalps. The gel texture gently removes any product build-up or dry flakes.

Lastly, a happy scalp is one with a balanced microbiome, so adding in Potentialiste Serum with its 10% Bifidus Prebiotic helps to feed the good bacteria in the scalp.
