What causes dandruff? Triggers and treatments you should know

In this article

Hair dandruff might seem like a minor concern, but it can have a major impact on both the health of your scalp and your overall confidence. The flakes and dryness associated with dandruff are often the result of an imbalance on the scalp, and if left untreated, it can lead to more serious skin irritation, itching, and even inflammation. This article will explore the reasons behind dandruff and offer according helpful solutions.

What is hair dandruff 

Hair dandruff is a common scalp condition characterized by the shedding of dead skin cells, often accompanied by itching and irritation. It occurs when the scalp becomes dry or overly oily, leading to the buildup of flakes that are visible on your hair and shoulders. This condition can be triggered by several factors, including fungal infections, sensitivity to hair products, or even stress.

While dandruff is typically not harmful, it can be a sign that something isn't quite right with your scalp's health. An imbalance in the scalp’s natural oils can cause an environment where yeast-like fungi thrive, contributing to the flaking. Read up to can dandruff causes hair loss?

What causes dandruff in hair 

Dandruff can stem from a variety of causes, but the most common culprit is a scalp imbalance—either too much oil or too little.

One of the most frequent causes is a fungal infection, particularly from a yeast-like fungus called Malassezia. This fungus naturally lives on the scalp, but when it grows uncontrollably, it can irritate the skin, leading to excessive flaking.

Other factors such as dry skin, cold weather, or using harsh hair products can also contribute to dandruff by making the scalp overly dry, which results in flakes. This is why dandruff often worsens during the winter months when moisture is stripped from both the hair and skin.

Another major cause of dandruff is sensitivity to hair products. Shampoos, conditioners, and styling gels containing harsh chemicals or fragrances can irritate the scalp, leading to flakes and itching. This sensitivity may be linked to allergic reactions, which can cause dryness and increased flaking.

How to treat dandruff in hair

By following these dandruff treatment strategies based on the underlying cause, you can effectively combat dandruff and restore a healthy, flake-free scalp.

Cause of dandruff

Treatment strategy

Fungal infection (Malassezia)

Use anti-fungal shampoos containing ingredients like ketoconazole, selenium sulfide, or zinc pyrithione. Regular use can control the fungus and reduce flakes.

Dry skin

Apply moisturizing shampoos and conditioners designed for dry scalp. Use oils such as argan or coconut oil to keep the scalp hydrated.

Sensitivity to hair products

Switch to hypoallergenic, fragrance-free hair care products to avoid irritation. Conduct a patch test before trying new products.

Poor hygiene

Ensure regular washing with proper shampoos to avoid buildup of oils and dead skin cells. Try to keep your scalp clean, especially during warmer months.

Stress and hormonal changes

Manage stress through regular exercise, proper sleep, and relaxation techniques. A balanced diet with vitamins can help regulate hormones.

How long does it take to lessen dandruff in hair

Generally, if you’re using an anti-dandruff shampoo or other targeted treatments, you may start seeing a reduction in flakes within one to two weeks. However, it’s important to continue with the treatment consistently for the best results. If you're dealing with a fungal infection or scalp sensitivity, it may take a bit longer—up to four weeks—before you notice a significant change.

How to blow out hair to reduce hair dandruff

Blowing out your hair correctly can be an effective way to reduce dandruff, as it helps to keep your scalp clean and healthy by avoiding excessive product buildup. When you use the right tools and techniques, you can minimize the scalp irritation that often accompanies dandruff. The Laifen Swift Special hair dryer is an excellent choice for this task. Its advanced ionic technology helps maintain your scalp's natural moisture while drying your hair quickly, which can reduce the chances of dry scalp flakes.

After applying your hair serum or oil, use the Laifen Swift Special on a low to medium heat setting. Its adjustable temperature settings allow for a customized drying experience, which helps avoid the harsh effects of high heat. Focus the airflow down the length of your hair, keeping it at a safe distance from your scalp to avoid any irritation. The result is healthy-looking hair with a well-moisturized scalp.
