The document reviewed the characteristics of the scalp to guide the development of scalp care products, emphasizing the importance of managing the scalp for healthy hair. It found that men are more prone to dandruff due to higher sebum levels and protein loss, and that racial differences affect sebum production and shampoo habits. The scalp's barrier function was linked to hair loss, with higher transepidermal water loss in hair loss areas. Dandruff was associated with lower natural moisturizing factor levels, and improving the skin barrier improved dandruff conditions. The review suggested that enhancing the scalp's barrier function could address dandruff and maintain scalp health. It also highlighted the role of tight junctions in maintaining the scalp's barrier function and the need for mild formulations to prevent barrier damage. Understanding customer complaints and their causes was deemed crucial for developing effective scalp care products.

research The Role of Tight Junctions in Skin Barrier Function and Dermal Absorption

156 citations , August 2016 in “Journal of controlled release”

This review summarizes current knowledge on tight junctions in mammalian skin and their role in drug delivery and interaction with other barrier components, but reports no new experimental results.

research Tight Junctions Form a Barrier in Porcine Hair Follicles

21 citations , December 2015 in “European journal of cell biology”

In this study, researchers demonstrated that follicular tight junctions in porcine skin form a barrier to nanoparticle penetration, particularly in upper regions, which supports its use as a model for human skin.
