I am sorry to hear this physedgirl
My hair was falling out like crazy at one point, it was very very depressing.
My doctor said that there are two types of hair loss: scarring and non-scarring. The scarring one destroys the hair follicle and is irreversible, while with the non-scarring one hair can grow back. She looked at my hair and said it was a non scarring hair loss. I have no idea how she came to that conclusion, but I decided to believe her.
Many months later I realized my hair loss was from mold toxicity, so I am not sure I can give advice on what could work (getting out of mold and taking kelp helped in my case, but I am experiencing some hair loss again with autumn, and my hair in the front hasn't fully grown back yet). However, I want to say that I had found many articles and blog posts online about
people with lyme having lost all of their hair and after they went into remission their hair fully grew back!
