🧴 Why Dandruff Doesn’t Go Away, and Smart Ways to Protect Your Scalp

Hello, this is Yonsei Bombit Dermatology.

If the white flakes piling up on your shoulders do not go away no matter how much you wash your hair, it may be a sign of a scalp issue rather than simple “dryness.” Today, I’ll explain why dandruff develops and share care methods you can practice every day.

Why Dandruff Doesn’t Go Away

🌬 Why does dandruff happen?

Dandruff is not just dead skin cells; it begins with a mild inflammatory reaction on the scalp. Common causes include:

• Irritation caused when Malassezia on the scalp breaks down sebum

• A dry or oily scalp environment

• Lifestyle factors such as excessive stress, lack of sleep, and weather changes

• Shampoo ingredients that do not suit you, or washing your hair too often

In short, dandruff is more likely to appear when the scalp falls into an imbalanced state.

🧼 How should you manage it?

1. Use a dandruff shampoo

Using an anti-dandruff shampoo recommended by a pharmacy or clinic is basic care.

Products containing ingredients such as “ketoconazole,” “zinc pyrithione,” and “selenium sulfide” are good options.

※ After applying shampoo to the scalp, you should leave it on for about 2–3 minutes while gently massaging before rinsing. This is necessary for the best effect.

2. Wash your hair every day, but not too often

Whether your scalp is oily or dry, washing once a day is best.

If you wash it two or three times a day just because your scalp feels oily, the skin barrier may break down and dandruff can actually get worse.

3. Your scalp also needs moisture

Just like skin, the scalp becomes sensitive when it gets dry.

After shampooing, it is also a good idea to lightly use a scalp-specific toner or moisturizer that contains ingredients that help retain moisture.

In particular, during winter, you need to pay attention because indoor heating can easily dry out the scalp.

4. Clean gently instead of scratching with your nails

Even if it itches, scratching with your nails can cause inflammation and leave scars.

When washing your hair, it is better to massage gently with your fingertips using light pressure.

5. Stress and diet also matter

Dandruff is also a skin signal that reflects your overall condition.

Improving your eating habits, such as drinking plenty of water, increasing intake of vitamin B complex and zinc, and reducing processed foods, can greatly help your skin.

✨ In these cases, a hospital visit is necessary

• If dandruff lasts for more than 2–3 weeks or gradually worsens

• If the scalp is red, stings, and looks inflamed

• If there is a strong odor even after washing your hair

• If dandruff appears along with hair loss

When simple care does not solve the problem, an accurate diagnosis and treatment may be needed.

🧭 In closing

Dandruff can happen to anyone, but with a small change in care methods, it can be reduced enough.

Please remember that the scalp is also skin, and rather than irritating it too much, help it recover slowly with balanced habits.

At Yonsei Bombit Dermatology, we accurately diagnose scalp conditions and help with treatment and care according to the cause.
