title: Transfollicular drug delivery--is it a reality?
abstract: Once regarded as merely evolutionary remnants, the hair follicles and sebaceous glands are increasingly recognised as potentially significant elements in the percutaneous drug delivery paradigm. Interest in pilosebaceous units has been directed towards their use as depots for localised therapy, particularly for the treatment of follicle-related disorders such as acne or the alopecias. Furthermore, considerable attention has also been focused on exploiting the follicles as transport shunts for systemic drug delivery. This paper reviews various key facets of this field including; relevant aspects of pilosebaceous anatomy and physiology, the design and efficacy of follicle-targeting formulations and the emergence of quantitative modeling systems. Several novel developments in this area promise to greatly expand our understanding of this field in the near future.
