She got sick out of both ends because she was so dizzy. She had anxiety and she has had a lot of grief and loss around her. It was not far fetched to say that the shock of the vaccine made her hair fall out. She thought the vaccine had stressed her body so bad that her hair fell off.

Her hair was brittle and breaking off and all over her pillow and clogging her drains. Patching of bald spots on the top of the her head could be seen, it was like the underlayer of her hair.
