Peeling skin

Megan

My son is 4 weeks old and has had peeling skin from day 1. I know its normal to a point and we have some hard water where we are so I know that contributes but the dry skin has gone away everywhere but his forehead. The skin there is patchy and almost scaley. It's not a diffrent color or anything but just to get some peace of mind should I be worried? And is there anything I can do to help fix it?
