Detailed answer

Seborrheic dermatitis is a common skin condition that causes redness, itching, and flaking. While the exact cause is unknown, several factors can contribute to its development, and dry skin is one of them. When the skin lacks moisture, it becomes more vulnerable to irritation and inflammation, making it easier for seborrheic dermatitis to occur. Dry skin can disrupt the skin's natural barrier, allowing irritants and allergens to penetrate more easily. Additionally, dryness can lead to excessive oil production as the skin tries to compensate for the lack of moisture, which can further contribute to the development of seborrheic dermatitis. Maintaining proper skin hydration through regular moisturization can help prevent and manage this condition.
