I had to take my pet to the doctor and I found out that he had swallowed a hair ball. The hair was not his own, it was mine. I have also noticed that my hair are fallen a lot lately. Enough to make someone choke on it, it is literally a ball size. Luckily I have thick hair so it does not really show, but I would want to prevent it. I have never changed shampoos often and have always stuck to one. Does stress cause hair loss? Please tell me how I can prevent the hair loss?
