Scalp Health
The condition of the scalp skin and follicular environment affecting hair growth.
Scalp health encompasses the condition of the scalp epidermis, dermis, sebaceous glands, and the follicular microenvironment. A healthy scalp maintains proper pH (4.5-5.5), balanced sebum production, intact skin barrier, and a diverse microbial community. Scalp conditions that impair hair growth include seborrheic dermatitis, psoriasis, folliculitis, and excessive inflammation. Nutritional factors supporting scalp health include zinc (sebum regulation, antimicrobial), omega-3 fatty acids (barrier function, anti-inflammatory), biotin (keratinocyte function), and vitamin D (skin cell differentiation).
