What is Dandruff?
Dandruff is a scalp condition characterised by excessive shedding of dead skin cells from the scalp. It can range from mild and occasional to severe and chronic. In some cases, dandruff may be accompanied by scalp redness, sensitivity, or greasy patches.
Contrary to popular belief, dandruff is not caused by poor hygiene. It is often due to a combination of factors including excess oil production, overgrowth of skin yeast (Malassezia), or underlying scalp disorders.
Common Symptoms of Dandruff
-
Flaky white or yellowish scales on the scalp or hair
-
Itchy scalp
-
Greasy or irritated scalp skin
-
Flakes visible on clothes or shoulders
-
Redness or sensitivity in some cases
What Causes Dandruff?
Dandruff can be caused by multiple factors:
|
Cause |
Description |
|
Seborrheic Dermatitis |
The most common cause of dandruff. It leads to inflamed, oily, and scaly skin, not just on the scalp but sometimes on the eyebrows, ears, and nose folds. |
|
Malassezia Overgrowth |
A naturally occurring yeast on the scalp that can overgrow and cause irritation and flaking. |
|
Dry Scalp |
Often seen in colder climates or from over-washing. Results in smaller, dry flakes without redness or oiliness. |
|
Hair Products (Contact Dermatitis) |
Certain shampoos, styling gels, or hair dyes can irritate the scalp and cause flaking. |
|
Psoriasis or Eczema |
Chronic skin conditions that can affect the scalp and mimic or worsen dandruff. |

Frequently Asked Questions (FAQ)
Is dandruff contagious?
No. Dandruff is not contagious and cannot be passed from one person to another.
Can dandruff cause hair loss?
Mild dandruff usually does not cause hair loss. However, severe or untreated scalp inflammation can contribute to hair shedding over time.
How often should I wash my hair if I have dandruff?
This varies depending on your scalp type and severity. In general, more frequent washing with a suitable medicated shampoo helps control flaking.
What if over-the-counter shampoos don’t work?
If standard shampoos aren’t effective, you may need prescription treatments or further assessment for underlying scalp conditions. Our dermatologists can help determine the best course of action.
