When studies on finasteride and rogaine mention regrowth, does regrowth refer to hair that was once not visible but has now come through the scalp again or hair that was visible but has thickened and has reversed miniaturization? I know not all people experience regrowth but do all people thicken hairs that have miniaturized? I haven't lost hair yet but it has diffusely thinned/miniaturized throughout the top and my scalp is more visible.
