Dandruff and dry scalp are two common scalp conditions that often get confused due to their similar symptoms, such as flaking and itching. However, understanding the differences between them is crucial for effective treatment. Dr Paras Chauhan emphasises that treating these conditions requires distinct approaches, as their causes and characteristics are quite different. Dandruff is typically associated with oily flakes and an itchy scalp, while a dry scalp produces smaller, dry flakes due to a lack of moisture. In this article, we will explore the differences between dandruff and dry scalp, discuss their causes, and provide expert advice on how to manage them.
Understanding Dandruff

Dandruff is a condition caused by an overgrowth of the fungus Malassezia, which thrives in oily environments. This leads to an accelerated shedding of skin cells, resulting in large, oily flakes that are often white or yellow. Dandruff is usually accompanied by an oily scalp, redness, and persistent itchiness. According to Dr Paras Chauhan, dandruff requires strong shampoos containing ingredients like Salicylic Acid, Zinc Pyrithione, and Ketoconazole to combat the fungal infection.
Understanding Dry Scalp

A dry scalp, on the other hand, is caused by a lack of moisture, leading to smaller, dry flakes. This condition can be triggered by factors such as cold weather, over-washing, or using harsh hair care products that strip the scalp of its natural oils. Unlike dandruff, a dry scalp feels tight and irritated but lacks oiliness. Dr Paras Chauhan suggests using moisturising, sulfate-free shampoos to treat a dry scalp.

Study on Scalp Conditions
A study highlighted that dandruff can lead to increased hair shedding due to the impaired barrier effect of the scalp's stratum corneum. This emphasises the importance of addressing dandruff promptly to prevent further complications. For a dry scalp, maintaining moisture is key to preventing flaking and irritation.
Identifying Dandruff vs. Dry Scalp
To differentiate between dandruff and dry scalp, Dr Paras Chauhan recommends a simple scratch test. If white flakes fall off like dust, it might be a dry scalp. However, if the scalp is oily and flakes stick to it, it could be dandruff. Here are some key differences:
- Flakes: Dandruff flakes are large and oily, while dry scalp flakes are small and dry.
- Scalp Condition: Dandruff is associated with an oily scalp, whereas a dry scalp feels tight and lacks oiliness.
- Treatment: Dandruff requires antifungal shampoos, while a dry scalp benefits from moisturizing shampoos.
