Getting rid of dandruff is one of the most common goals in scalp care.
The problem is widespread and can be not only cosmetically bothersome,
but also uncomfortable.
It is caused by an accelerated turnover of scalp cells,
which produces visible flakes of skin.
The causes range from a dry or oily scalp to skin conditions
such as psoriasis or seborrhoeic eczema.

Causes of dandruff

Dandruff can be triggered by various factors:

Dry scalp:

If the skin lacks moisture, it renews itself faster – small, white flakes form.
Hot blow-drying, harsh shampoos or cold winter air can make this worse. [Source]

Oily scalp:

Excess sebum creates ideal conditions for the yeast Malassezia furfur.
It feeds on skin oils and leads to oily, yellowish flakes. [Source]

Skin conditions:

Psoriasis or seborrhoeic eczema significantly accelerate skin renewal,
which can encourage stubborn dandruff and inflammation. [Source]

Stress & diet:

An unbalanced lifestyle, lack of sleep or nutrient deficiencies
affect the skin's environment and encourage dandruff.

Getting rid of dandruff – classic and modern approaches

Choosing the right approach depends heavily on the cause:

Anti-dandruff shampoos:

Shampoos containing zinc pyrithione or piroctone olamine regulate sebum production
and slow down the formation of new cells.

Home remedies:

Natural oils or aloe vera provide moisture –
but their effectiveness varies from person to person.

Red light therapy:

A modern way to get rid of dandruff.
Red and near-infrared light have an anti-inflammatory effect, promote circulation
and can support the regeneration of the scalp –
a gentle option for sensitive skin.

Why red light therapy can help you get rid of dandruff

1. Anti-inflammatory effect

Dandruff is often linked to inflammation.
Red light modulates the immune response and reduces pro-inflammatory messengers –
itching and redness can subside.

2. Better circulation in the scalp

Improved microcirculation supplies hair roots and skin cells
with oxygen and nutrients.
This helps the scalp to regain its natural balance.

3. Regulating sebum production

Red light therapy helps to balance the activity of the sebaceous glands.
This reduces both oily and dry dandruff.

4. Antimicrobial support

The method can have a positive influence on the skin microbiome,
which can inhibit the excessive growth of Malassezia.

5. Repairing the skin barrier

By promoting collagen production and cell repair,
red light supports the regeneration of the scalp –
important for getting rid of dandruff in the long term.
