Hi. My son is 5 months old. From past couple of days approx. 20-25 days his head hairs are falling. When he was born his head was full of hair. But now his hair falling from sides nd center of the head. I noticed so many hairs on his pillow nd sheet. I need to know is this normal or he has some deficiency? I have not heard something like this earlier. I am very much worried about him. His head is now like bald head. Lil bit hairs are there.
