Dandruff is a common scalp condition experienced by millions of people around the world. While it’s not harmful, it can be uncomfortable and embarrassing, often leading to flakes of skin visible on the scalp, hair, and clothing. These flakes are dead skin cells on the scalp, and when the skin on the scalp has too much oil (called sebum), the flakes fall off faster than before.
Dandruff can be caused by many things, including overgrowth of the Malassezia bacteria, overuse of hair care products, and certain skin conditions. problems. Fortunately, treatments such as special anti-dandruff shampoos are available over the counter or by prescription to help control dandruff.
Causes of Dandruff
- Dry Skin Dandruff: This is one of the most common causes of dandruff. Dry, cold weather can lead to dry skin on the scalp, causing it to flake. This type usually occurs due to excessive dryness of the scalp which causes dandruff to fall out. This type can be caused by bad weather, lack of moisture, or hair care products that strip the scalp of its natural oils.
- Oily Scalp: Excessive oil on the scalp can trap dead skin cells, leading to the formation of dandruff. When mixed with oil, these cells can clump together and appear more noticeable. As a result, you will experience oily scalp and more yellow dandruff.
- Not Washing Hair Enough: Irregular hair washing can allow oil and dead skin to accumulate, leading to dandruff formation. Not washing your hair regularly can lead to a buildup of oil, dead skin cells, and dirt on the scalp. This creates an environment where dandruff can form, making flakes more noticeable and potentially causing irritation.
- Malassezia Fungus: This fungus naturally lives on the scalp but can sometimes grow out of control. This can irritate the scalp, leading to increased skin cell turnover, resulting in dandruff. Malassezia works on sebum, and too much oil can cause fungal growth, causing inflammation and scaling of the skin.
- Hormonal imbalances, weakened immune systems, and skin conditions can disrupt the balance of the scalp and cause dandruff. Although these factors make dandruff more difficult to manage, treating the underlying health problem can help with symptoms, although treatment may be more difficult.
