Persistent flakes, itching, burning sensations or an itchy scalp…
These symptoms are extremely common and often trivialized. However, when they last or worsen, they generally indicate a scalp imbalance that requires medical attention.

At ANAGEN, we receive patients every day who have tried everything: anti-dandruff shampoos, natural remedies, changes of products without lasting results.
Here’s how to understand the true causes, know when to consult, and discover the medical treatments that truly work.

Why does the scalp become irritated?

The scalp is a particularly sensitive skin area, rich in sebaceous glands and nerve endings.
Several mechanisms can cause irritation and itching:

• Imbalance of the skin microbiome

• Excess or lack of sebum

• Chronic inflammation

• Reaction to hair products

• Stress and fatigue

• Hormonal imbalances

• Climatic factors (cold, heat, pollution)

👉 Identifying the precise cause is essential for effective treatment.

The most common medical causes

1. Seborrheic dermatitis

This is one of the most common causes of dandruff and itching.

Symptoms:

• Greasy, yellowish flakes

• Intense itching

• Localized redness

• Areas often affected: scalp, eyebrows, sides of the nose

👉 It requires targeted medical management, beyond conventional shampoos.

2. Dry scalp

Contrary to popular belief, flakes can also be due to excessive dryness.

Symptoms:

• Fine, white flakes

• Tightness

• Sensation of a “burning” scalp

• Worsening in winter

3. Chronic inflammation

A repeatedly irritated scalp can become inflammatory.

Possible consequences:

• Persistent itching

• Increased sensitivity

• Associated hair loss

• Weakening of follicles

👉 Untreated inflammation can ultimately promote hair loss.

When should you see a specialist?

It is recommended to consult when:

• Symptoms persist for more than 2-3 weeks

• The itching is daily

• Dandruff returns despite treatments

• Redness or pain appears

• Associated hair loss is present

👉 The earlier the intervention, the quicker and more durable the results.

Common mistakes to absolutely avoid

❌ Using aggressive anti-dandruff shampoos excessively
❌ Scratching the scalp (worsens inflammation)
❌ Changing products too frequently
❌ Applying unsuitable solutions found online
❌ Ignoring persistent symptoms

These reflexes can worsen the imbalance of the scalp.
