INDIVIDUAL ARTICLE: Insights on the Impact of Scalp Barrier Condition on Hair Health.

Scalp health is essential for healthy hair growth and may be affected by intrinsic or extrinsic factors. Reactive oxygens species are key contributors to aging and can have a detrimental impact on scalp health. Oxidative stress on the scalp is thought to be a factor in developing dandruff. We present consensus statements on scalp barrier health and its effects on hair through a systematic literature search and expert panel discussion. Three dermatologists with extensive experience in hair were selected to form a panel that formulated consensus statements that would best capture the current understanding of scalp health. The consensus statements developed and presented in this manuscript highlight the current literature and broader discussion surrounding scalp health and its impact on hair and dandruff. It also highlights the often-overlooked effects of scalp conditions on hair health and growth. Through our research, we found that there has been minimal emphasis on scalp health in the setting of dandruff, with most studies focusing on other inflammatory diseases such as psoriasis and atopic dermatitis. Here, we review the clinical importance of focusing on the impact of the scalp barrier condition on hair health. J Drugs Dermatol. 2025;24:2(Suppl 1):s3-7.
