Aim: A comparison of permeation ability of selected semi-permanent hair dyes and an attempt to estimate the influence of fundamental physicochemical parameters on dyes' epidermal penetration rate.

Methods: Dyes' permeation ability through liposome membrane (as a model of stratum corneum) with side-by-side cells was assessed.

Results: It has been shown that the chosen dyes are capable of permeating the membrane.
