Dandruff is a common scalp condition characterized by itching and flaking of the skin on the scalp. Many seek ways to treat this frustrating issue; fortunately, numerous home remedies and natural treatments are available. It is crucial to understand the underlying causes of dandruff to select the most effective treatment options.
Various factors contribute to dandruff, including excessive oil production, dry skin, or sensitivity to hair care products. Moreover, a fungus called Malassezia is often responsible for the condition. Identifying the primary cause is essential for choosing or combining suitable remedies to combat dandruff, as different solutions are tailored for distinct situations.
In recent years, several natural remedies have gained popularity for their efficacy in treating dandruff. These may include apple cider vinegar, tea tree oil, and coconut oil. Utilizing these treatments can help soothe the scalp, reduce itching and flaking, and restore a healthy balance to the skin—all while limiting exposure to potentially irritating chemicals found in some conventional products.
What is Dandruff?
Dandruff is a common scalp condition characterized by small, white flakes of dead skin that are shed from the scalp. It is typically harmless but can be embarrassing and sometimes cause itching or irritation.
Causes of Dandruff
Several factors can contribute to dandruff, including:
- Seborrheic dermatitis: This is a common skin condition that affects oil-producing areas of the body, including the scalp, and can lead to dandruff. It causes red, greasy patches with white or yellow scales.
- Malassezia: This is a type of yeast that lives on the scalp and feeds on oils. In some people, it can grow excessively and irritate the skin, causing the scalp to shed more skin cells than usual.
- Dry skin: If your scalp is dry, it is more prone to flaking, resulting in dandruff.
- Improper hair care: Not washing your hair regularly can lead to excess oil and skin cell buildup, resulting in dandruff. On the other hand, overwashing your hair can strip it of necessary oils, leading to dryness and flaking.
- Sensitivity to hair care products: Some individuals may be sensitive or allergic to certain ingredients in hair care products, which can cause irritation and dandruff.
Types of Dandruff
Dandruff can be classified into two main types:
- Dry dandruff: This type occurs when the scalp is dehydrated. Flakes are small, white, and powdery. Harsh hair care products, environmental conditions, or improper hair care usually cause it.
- Oily dandruff occurs when excess oil is produced on the scalp. Flakes are larger, greasy, and yellowish. It is commonly associated with seborrheic dermatitis or overactive sebaceous glands.
Understanding the causes and types of dandruff can help you choose the most appropriate treatments and remedies to manage this condition effectively.

Another popular home remedy is aloe vera gel, which can be rubbed onto the scalp and rinsed off after 30 minutes to treat dry hair and scalp.
Essential oils can also play a role in reducing dandruff symptoms. Tea tree oil has antimicrobial and anti-inflammatory properties, which may help alleviate dandruff severity. Additionally, coconut oil is renowned for its numerous health benefits, including its ability to moisturize the scalp and reduce dryness.
Diet and Lifestyle Changes

Regularly using these shampoos can help reduce dandruff by eliminating excess oil, controlling itching, and slowing down the growth of dandruff-causing fungi.
In addition to anti-dandruff shampoos, medicated shampoos can be used to treat more severe cases of dandruff. These shampoos often contain different active ingredients that target specific causes of dandruff.

Although many dandruff cases can be managed with over-the-counter shampoos, more severe cases may require professional treatments. These may include prescription shampoos and topical medications focusing on controlling symptoms or targeting underlying causes.
One potent prescription shampoo is ketoconazole shampoo (Nizoral Anti-Dandruff), formulated to kill dandruff-causing fungi on the scalp. Another option is fluocinolone shampoos (Capex, Derma-Smoothe/FS, others), containing a corticosteroid to control itching, flaking, and irritation.
Apart from prescription shampoos, there are medicated shampoos containing various active ingredients, such as:
- Pyrithione zinc (Selsun Blue for Itchy Dry Scalp, Neutrogena T/Gel Daily Control Dandruff Shampoo, Head & Shoulders)
- Salicylic acid and sulfur (Sebex, Sebulex)
