Anti-dandruff shampoo: how to choose the right one?

Dandruff is never “trivial”

Whether dry, oily, diffuse or localized, dandruff is a sign of a biological imbalance of the scalp.
They often reveal:

• an alteration of the microbiome,

• persistent inflammation,

• an excess or lack of sebum,

• sometimes even worsened hair loss.

The choice of the right anti-dandruff shampoo is therefore not simply cosmetic :

It must be dermatological, soothing, antifungal, rebalancing, and respect the integrity of the scalp.

RENASCOR Laboratory — a world reference in post-oncological scalp reconstruction — reminds that dandruff is as much an inflammatory problem as a microbial one, and that only a scientific approach allows lasting improvement.

1. Why does dandruff appear? Understand before treating

1.1. Microbiome imbalance

Most dandruff is linked to an excessive proliferation of yeasts of the Malassezia type.
When their presence exceeds a certain threshold, they trigger:

• flaking,

• redness,

• irritations,

• itching,

• sometimes a loss of density.

1.2. Scalp inflammation

Inflammation is the heart of the problem.
It weakens the epidermis, sensitizes the fiber, and can amplify an existing hair loss.

1.3. Sebum imbalance

Two main cases:

• dry dandruff → white flakes, slight shedding

• oily dandruff → yellowish, sticky, inflammatory patches

1.4. Triggering factors

• stress and fatigue

• pollution

• overly occlusive treatments

• harsh shampoos

• hormonal variations

• genetic predisposition

An anti-dandruff shampoo should therefore:

✔ rebalance
✔ soothe
✔ cleanse without stripping
✔ treat the microbial cause
✔ restore the skin barrier

2. The 5 essential criteria for choosing a good anti-dandruff shampoo

2.1. Effective antifungal action

The primary role of an anti-dandruff shampoo is to limit the proliferation of Malassezia, responsible for a large part of dandruff.

2.2. A real anti-inflammatory action

Without reduction of inflammation, dandruff recurs.
You need a formula that soothes:

• redness,

• irritations,

• burning sensations,

• scratching.

2.3. A non-drying formula

Many anti-dandruff shampoos “strip”.
This is a mistake: it further weakens the scalp and increases sebum production.

2.4. A controlled antibacterial action

It helps stabilize the skin ecosystem and prevent recurrences.

2.5. High dermatological tolerance

Essential for :

• sensitive scalps,

• stressed people,

• chronic dandruff,

• post-cancer treatment care.

3. How to choose according to your type of dandruff?

3.1. Dry dandruff

✔ gentle shampoo
✔ anti-inflammatory
✔ non-drying

3.2. Oily dandruff

✔ enhanced antifungal
✔ sebum regulator
✔ rebalancing action

3.3. Dandruff + itching

Very common, linked to inflammation.
✔ anti-itch
✔ immediate soothing
✔ mild antifungal

3.4. Dandruff + hair loss

Inflammation destroys follicular anchoring.
✔ antifungal
✔ anti-inflammatory
✔ antibacterial
✔ compatible with an anti-hair-loss serum
