Transfollicular Drug Delivery Systems

The document discussed the potential of hair follicles as a route for drug delivery, highlighting their complex structure and interaction with various cells and molecules. It reviewed several studies showing that transfollicular drug delivery could enhance the absorption of topical and systemic medications, including minoxidil, adapalene, and caffeine. Techniques such as using foams, microemulsions, and liposomes were found to improve drug penetration through hair follicles more effectively than traditional methods. The findings suggested that transfollicular delivery could be a promising alternative to other drug delivery methods, particularly for large or hydrophilic molecules.
