There are several factors that can contribute to the development of dandruff, including:
Malassezia fungus: Dandruff can be caused by an overgrowth of the fungus called Malassezia on the scalp, which can cause irritation and inflammation.
Seborrheic dermatitis: This is a common skin condition that causes red, itchy, and flaky skin. It can occur on the scalp and cause dandruff.
Oily scalp: People with an oily scalp are more prone to dandruff because the excess oil can contribute to the buildup of dead skin cells on the scalp.
Dry skin: People with dry skin may also develop dandruff because of the buildup of dead skin cells on the scalp.
Sensitivity to hair care products: Certain hair care products can irritate the scalp and cause dandruff.
Medical conditions: Some medical conditions such as psoriasis, eczema, and Parkinson's disease can cause dandruff.
It's important to identify the underlying cause of dandruff to effectively treat and prevent it from recurring. If you're unsure of the cause, consider consulting a dermatologist for a proper diagnosis and treatment plan.
