No, air conditioning doesn't directly cause dandruff. However, it can worsen existing dry scalp conditions, which may be mistaken for dandruff. Air conditioning removes moisture from the air, leading to dry skin, including the scalp. This dryness can cause itching, flaking, and irritation—symptoms often associated with dandruff.
How Air Conditioning Affects Your Scalp
-
Dryness: As stated in multiple sources, including Elle Magazine (https://www.elle.com/beauty/hair/a24736798/dry-scalp-treatment-remedies/) and Head & Shoulders (https://headandshoulders.com/en-us/healthy-hair-and-scalp/dandruff/5-surprising-causes-behind-itchy-scalp), air conditioners dehumidify the air. This dry air can strip your scalp of its natural oils, leading to dryness and flaking. This effect is particularly noticeable during summer months. A November 2018 article (https://www.elle.com/beauty/hair/a24736798/dry-scalp-treatment-remedies/) highlights that both winter's dry air and summer's air-conditioned air contribute to scalp dryness.

Exacerbating Existing Conditions: If you already have a dry scalp or a tendency towards dandruff, air conditioning can exacerbate these problems. The dryness caused by air conditioning can make existing flaking more noticeable and potentially increase itching.
-
Confusion with Dandruff: The dryness and flaking caused by air conditioning can easily be mistaken for dandruff. However, true dandruff is a fungal condition, while air conditioning-related flaking is primarily due to dryness.
-
Other Factors: Remember that many factors contribute to dandruff, including genetics, diet, stress, and hygiene. Air conditioning is one environmental factor among many that can affect scalp health.
Differentiating Dry Scalp from Dandruff
It's important to note the difference. While both present with flaking, dandruff often involves yellowish, greasy scales and intense itching. Dry scalp typically presents with smaller, whiter flakes and milder itching.
