Dandruff and Scalp Issues: Causes, Symptoms, Treatment and Prevention – A Dermatologist’s Guide
Dandruff is a very common scalp concern that affects individuals of all ages. Although it is not harmful, it can cause itching, discomfort and sometimes lead to increased hair fall. Understanding the reasons behind dandruff and receiving proper treatment can greatly improve scalp health.
This guide explains the causes of dandruff, similar scalp conditions, treatment options, home remedies and prevention methods in a professional and easy-to-understand way.
What Is Dandruff
Dandruff is the shedding of dead skin cells from the scalp. These flakes may be white or yellow and are often accompanied by itching, dryness or oiliness. While not contagious, dandruff can become chronic without proper care.
Common Causes of Dandruff
- Oily Scalp (Seborrheic Dermatitis)
Excess oil promotes yeast overgrowth, causing inflammation and flaking.
- Dry Scalp
Lack of moisture leads to a tight, itchy and flaky scalp.
- Fungal Overgrowth
Imbalance in scalp microbes increases fungal activity.
- Product and Dirt Build-up
Heavy hair products and oils can irritate the scalp.
- Stress and Hormonal Fluctuations
These can increase scalp oiliness and worsen dandruff.
- Improper Hair Care Routine
Over-oiling, infrequent washing or harsh shampoos disturb scalp balance.
Scalp Conditions That Look Like Dandruff
- Scalp Psoriasis
Thick, silver-white scales with red patches.

Reaction to hair dyes, shampoos or chemicals.
