I have been experiencing a strange feeling on my scalp. It is sometimes itchy or it just tingles and i feel the need of pulling hair out in that zone for a moment. When I do I feel a sense of relief and the hair comes out with a white bulb at the root and i was told that is hair during telogen phase which was supposed to be shed anyway. Is this good? I am 20 years old and I am scared of the fact that it might mean I'm balding even though i have a full head of hair except two small temples on the sides which I have always had. I also lose some hair in the shower or when I run my hand through my hair.
