Summer can be hard on your hair. It is put through the paces with the sweat, humidity, pollution and dirt that are common in Indian summer weather. This can lead to many people facing issues like their
hair feeling oily more often, looking limp and dull or just having to deal with itchiness due to the sweat. Some might even get a flaky scalp due to dandruff.
Dr Ankur Sarin, Dermatologist, Sarin Wellness, say, “Many assume that dandruff is just the white flakes that are on your scalp or in the hair. But, in clinical practice, we commonly see two different patterns — oily dandruff and dry dandruff. Both can cause flaking and itching, but the scalp environment, type of flakes and recurrence pattern can differ significantly.”
Understanding which type of dandruff you have can help in choosing the right scalp care, especially during the summer season. Using random shampoos without understanding your scalp can give you some temporary relief, but the flakes will keep returning.
What Causes Dandruff?
Dandruff is a common scalp condition linked to an imbalance involving a naturally occurring yeast called Malassezia. This organism lives on most human scalps and feeds on sebum, the natural oil produced by the scalp.
In some individuals, the scalp becomes sensitive to the by-products produced when this yeast breaks down sebum. This irritation can lead to inflammation and faster turnover of skin cells.
Dr Ankur Sarin says, “Normally, scalp skin sheds invisibly. But when cell turnover speeds up, these cells accumulate and appear as visible flakes. Genetic tendency, stress, and certain hair products can worsen this imbalance, making the scalp flake more and feel itchy. Mild itching, irritation and redness can also occur.” The amount of oil present on the scalp often influences how dandruff appears, which is why the condition can show up as either oily or dry flaking.
Oily Dandruff: When Excess Oil Drives the Flaking
Oily dandruff usually appears as yellowish or off-white flakes that look slightly sticky or clumped together. These flakes often stick to the scalp or nails rather than falling freely on clothing. The scalp may feel greasy within one or two days after washing. Itching is usually persistent but moderate. Some people may also notice mild redness.
What’s Happening on the Scalp
Excess sebum creates a favourable environment for Malassezia yeast to grow more actively.
Factors that can worsen oily dandruff include:
• humid weather
• sweating
• helmet use
• heavy styling products
• infrequent scalp cleansing
Simply washing more often or using cosmetic shampoos may remove surface oil temporarily, but they do not control yeast growth, so flakes tend to return quickly.
Dry Dandruff: Fine Flakes That Fall Like Snow
Dry dandruff appears as fine, powdery white flakes that easily fall onto the shoulders, especially visible on dark clothes. The scalp may feel slightly tight or dry. Itching is usually mild to moderate rather than intense.
What’s Happening on the Scalp
Dry dandruff is often confused with simple scalp dryness caused by cold weather, harsh shampoos or over-washing. However, recurrent fine flaking is still frequently associated with Malassezia-related irritation, even if the scalp does not feel very oily. This means that simply increasing oiling or switching to moisturising shampoos may improve comfort but may not completely resolve the flaking.
Why Each Type Needs Slightly Different Care
The key difference between oily and dry dandruff lies in scalp oil levels and flake texture.
* Oily dandruff – requires controlling excess oil along with antifungal action.
* Dry dandruff – requires maintaining scalp balance without excessive stripping, while still addressing yeast activity.
Many regular shampoos simply cleanse the hair. They may wash away flakes temporarily but do not treat the underlying microbial imbalance.
For better control, it helps to look for clinically studied antifungal ingredients. One such ingredient is Piroctone Olamine, which helps reduce the growth of dandruff-associated yeast.
Benefits of Piroctone Olamine:
• Effective antifungal activity
• Gentle on the scalp barrier
• Suitable for regular use
• Works across different climates and scalp types
How to Identify Your Dandruff Type
A few simple observations can help:
• Does your scalp become greasy quickly after washing?
• Are the flakes sticky and clumped?
• Or are they fine and powdery?
• Do flakes persist even when you moisturise the scalp?
A simple home check is to press a small strip of butter paper on the scalp parting. If it quickly shows oil marks, your scalp may lean toward the oily side.
Dr Ankur Sarin says, “Oily and dry dandruff may look different, but both are linked to scalp imbalance and yeast activity. Understanding your dandruff type helps you move away from trial-and-error and choose more targeted scalp care. Checking the ingredient list and using shampoos with proven antifungal ingredients regularly can help maintain long-term scalp health. Consistency matters because dandruff is a recurring condition that needs ongoing scalp care, not a one-time fix.”
