If there is no follicular edema on certain areas being treated, does this mean these areas wont respond well? (photo)

my doctor/tech told me that follicular edema is a good sign (I usually always see it around my bikini zone) but I hardly see it around my legs or buttocks. I am concerned with the buttocks, the hair is thickest in the crack and gradually thins out as it reaches the outer regions of the cheeks. I read that areas with thick skin and/or lighter hair will not respond as well to the laser. please help, the photos may not be a big help since I am recently shaved. I am being treated with 1064 ndYAg
