This item contains two textures: an alpha-map and a bumpmap. Combine those as shown in the picture "Cycles_Shader". This is an additional hair-mesh to be combined with the scalp "Hair_male_half_bald". You have to give credits to Nathan Vegdahl, Beorn Leonard, and Jonathan Williamson, based on an initial design by David Revoy.
