I have severe dry skin, it is tight and looks like alligator skin. I had to shave off layers and layers off of my big toe. I have a scab under my hair on my scalp. I think this is from dry skin. I went to dr. and all she did was give me a list of things not to do. My tonuge is dry and cracked also. Is this a sign of dehydration? Do I have some kind of disease? I am 50 next month. Oh, I also have excessive facial hair I have to shave everyday. Are my hormones all messed up or what? Ifoundittoo
