Dear girls, could someone tell me if they've experienced this? Very dry skin has become more prominent since pregnancy, especially on the scalp, near the forehead. I scratch it and there's this feeling like dandruff, but I don't have any dandruff at all. Maybe some oil or something else? I apply cream to my face, but I don't know what to do with the scalp. ?
