What Are the Symptoms of Seborrheic Dermatitis?

The most common symptoms include:

• Flaking skin (often dandruff on the scalp)
• Red or inflamed patches
• Itching
• Greasy or yellowish scales
• Dry or sensitive skin

These symptoms may appear alone or together.

Managing these symptoms often starts with the right cleansing routine, explained in Best Shampoo for Seborrheic Dermatitis.

Mild vs Severe Symptoms

Mild symptoms

• Light flaking
• Occasional itching
• Slight dryness

At this stage, signs are often mistaken for simple dandruff. Knowing the dandruff vs seborrheic dermatitis difference is helpful here to determine if you need a standard hydrating routine or a more targeted treatment for your scalp.

Moderate to severe symptoms

• Persistent flaking
• Redness and inflammation
• Noticeable itching
• Thick scaling

These symptoms usually require more consistent treatment.

Symptoms of Seborrheic are very similar to those of Eczema. You can read more in our Symptoms of Eczema guide.

Why Seborrheic Dermatitis Causes Flaking

Flaking happens because:

• Skin cells renew too quickly
• Oil and yeast interact on the skin
• The skin becomes inflamed

This leads to visible flakes and irritation.

When Symptoms Become More Noticeable

Flare-ups can occur:

• During periods of stress
• In colder months
• When using irritating products

Recognising patterns helps you manage symptoms better.
