Core Viewpoint - The "white mud" found on the scalp after several days without washing is not just dirt but a warning signal for scalp health, indicating an abnormal scalp metabolism and the presence of oily dandruff [1][3]. Group 1: Composition of Scalp Dandruff - Scalp dandruff consists of 50% to 80% of shed keratinocytes, 10% to 30% of skin oils, and 5% to 15% of microorganisms, along with sweat and external dust [4]. - The formation of "white mud" is closely related to an increase in sebum secretion, which occurs when the combined proportion of sebum and microbial metabolic products exceeds 40% [4][6]. Group 2: Factors Influencing Sebum Production - Sebum is produced by sebaceous glands and is significantly influenced by androgens, explaining the increase in oily scalp during puberty [6]. - Dietary habits, irregular sleep patterns, and emotional stress can also affect sebum production, with high sugar and fried food consumption leading to increased oiliness [6]. Group 3: Health Implications of Excess Sebum - Excessive sebum can create an environment for the proliferation of Malassezia, a fungus that can lead to scalp inflammation and increased dandruff [9]. - The presence of Malassezia can break down sebum into irritating fatty acids, exacerbating scalp issues and contributing to the formation of "white mud" [9]. Group 4: Warning Signs for Scalp Health - Yellowish-white flaky scales may indicate seborrheic dermatitis, which can be treated with antifungal shampoos [12]. - Thick silver-white scales could suggest psoriasis, a systemic disease that may require specialized medical attention [15]. - Dry flakes with hair loss may indicate tinea capitis, necessitating antifungal treatment [18]. - Red bumps on the scalp may signal bacterial folliculitis or impetigo, requiring specific treatments [19]. - The presence of lice eggs on hair strands indicates pediculosis capitis, which can be treated with insecticides [22]. Group 5: Recommendations for Scalp Care - Recommended washing frequency varies: oily hair should be washed daily or every other day, while dry hair can be washed every 3 to 4 days [22]. - Use warm water not exceeding 38°C to avoid stimulating excessive sebum production [23]. - Gentle scalp massages with fingertips are advised to prevent damage from nails [24]. - Choosing appropriate hair care products under dermatological guidance is essential, especially for those with seborrheic dermatitis [24]. - Maintaining a balanced diet, regular sleep, and a positive mindset can help manage scalp health [24].
