for the last month I have been experiencing a very sudden and unexplained hair loss. I already have several bald patches some of them large. All my life I have had very thick hair and there is no family history of hair loss. Has anyone else experienced this? I'm scared and stressed and I don't know what to do. My hair is falling out all the time but worse when I wash my hair. Is this normal and how long does this excessive hair fall last? I had thick hair before how long before it all goes? Sorry for so many questions but I guess it's early days for me.
