Female Hair Loss — Is it Because of New Shampoo or Cancer or What?

Hi. I am a 36 yr old female. I have lost approx 60-70% of my hair in the past month. Scary. I had a kidney/liver and thryroid blood test done which came back normal. I am just so worried. Could this be a sign of cancer or something terrible. New hair is growing in a little, but I think I’ll have to shave my head. I understand the stress related hair fall and am not sure this could apply to me. Is it possible to have this reaction to a new shampoo? I have always used natural shampoos but have lately used a cheaper drugstore shampoo…any ideas?
Thank you in advance.

You need to see a dermatologist or hair doctor to make a diagnosis. Something is wrong and there is no substitute for a good doctor’s examination. Perhaps it is as simple as an allergy to an ingredient in the new shampoo? Perhaps it is something more. I couldn’t possibly determine that via the Internet.
