my 3 months old baby girl is getting hair fall heavily at head back side ,is it ok or any issue please tell me . actually she had thick hair now hair is falling it's looks like balled hair

A. It is a condition like alopecia where the hair actually fall completely from the root and leave plain skin where you cannot even see roots so this is looking like that only but I’m not very sure because you’re saying hair fall and it’s looking like bald only so better to consult the doctor once
