Dandruff is a condition where the scalp sheds skin cells faster than normal. Everyone’s scalp naturally renews skin cells, but when this process speeds up, it leads to visible flakes.
Dandruff can be:
- Dry and powdery
- Oily and sticky
- Mild or severe
- With or without itching
It is not contagious, meaning it does not spread from person to person.
Dandruff can affect:
- Teenagers and adults
- People with dry or oily scalp
- Men more commonly than women
- People under stress or hormonal imbalance
Common Causes of Dandruff
1. Dry Scalp
A dry scalp is one of the most common causes of dandruff. It usually gets worse in cold weather or due to lack of moisture.
Signs:
- Small white flakes
- No redness
- Less oil on scalp
2. Oily Scalp (Seborrheic Dermatitis)
Too much oil on the scalp can trap dirt and dead skin cells, leading to dandruff.
Signs:
- Yellow, greasy flakes
- Itchy scalp
- Redness around scalp, eyebrows, or ears
3. Fungal Growth (Malassezia)
A natural fungus called Malassezia lives on everyone’s scalp. When it grows too much, it irritates the scalp and causes excessive skin shedding.
4. Poor Hair Hygiene
Not washing hair regularly can cause oil and dead skin buildup, which leads to dandruff.
5. Using Harsh Hair Products
Shampoos, conditioners, or styling products with chemicals, alcohol, or fragrance can irritate the scalp and cause flaking.
6. Stress
High stress levels can weaken the immune system, making the scalp more prone to dandruff.
7. Hormonal Changes
Hormonal imbalance can affect oil production on the scalp, which may trigger dandruff, especially during puberty or adulthood.
8. Poor Diet
Lack of essential nutrients like:
- Zinc
- Vitamin B
- Omega-3 fatty acids
can contribute to scalp dryness and dandruff.
9. Weather Changes
Cold, dry winters and humid summers can both worsen dandruff by affecting scalp moisture and oil balance.
Is Dandruff a Serious Problem?
Dandruff is not a serious medical condition, but if it becomes severe, persistent, or painful, it may indicate another scalp issue like psoriasis or fungal infection.
