In the first texture stage, load the hair color with a texture environment of GL_DECAL or GL_MODULATE (depending on whether you need to incorporate the vertex color). In the second texture stage, overwrite the fragment's alpha value with the mask texture using GL_REPLACE. The mask texture has to be stored as GL_ALPHA.
