What is Dandruff?

Dandruff is a scalp condition characterized by the shedding of dead skin cells, often appearing as white or yellow flakes. Unlike common belief, dandruff is frequently associated with an oily scalp rather than dryness. This is due to the overproduction of sebum by the sebaceous glands, creating an ideal environment for the naturally occurring fungus Malassezia. As the fungus feeds on the sebum, it produces oleic acid, which irritates the scalp and accelerates skin cell turnover, leading to visible flakes.

Dandruff vs. Dry, Flaky Scalp

It’s important to differentiate dandruff from a dry scalp. Dry scalp typically produces fine, white flakes and is often itchy due to lack of hydration. Dandruff, on the other hand, involves larger, sometimes yellowish, often oily, caused by microbial activity. Misdiagnosis can lead to inappropriate treatments, such as over-moisturizing shampoos, which may worsen the condition.

Seborrheic Dermatitis

Seborrheic dermatitis is a more severe form of dandruff affecting not only the scalp but also other oily areas like the face and chest. It manifests as red, greasy patches covered with white or yellow scales. Persistent seborrheic dermatitis can cause hair thinning if left untreated. Our Scalp Treatment Oil is particularly effective for softening and removing this buildup.

Symptoms and Triggers

Common symptoms of dandruff include:

• Flakes: White or yellowish, often visible on shoulders.
• Itching and irritation: Caused by inflammation and microbial activity.
• Redness and sensitivity: Due to scalp irritation and oil accumulation.

Triggers include:

• Oily skin: Excess sebum promotes fungal growth.
• Hormonal changes: Puberty, menstruation, and stress can alter oil production.
• Stress: Weakens the immune system, allowing Malassezia to thrive.
• Diet: Nutrient deficiencies can impair scalp barrier function.
• Environmental factors: Extreme humidity, cold, or dry air can exacerbate symptoms.

The Science of the Scalp Microbiome

The scalp is home to a complex ecosystem of microorganisms. While Malassezia is a natural inhabitant, overgrowth triggers inflammation and flaking. Recent studies highlight the importance of maintaining microbial balance using gentle, pH-balanced products and reducing triggers like stress and poor nutrition. Antioxidant-rich ingredients, essential oils, and mild acids like apple cider vinegar can support a healthy scalp microbiome and reduce dandruff severity.

• Stress management: Yoga, meditation, and regular exercise lower cortisol and prevent scalp flare-ups.
• Hydration: Adequate water intake maintains skin elasticity and moisture.
