Why does my eyebrows and lashes thin out after Botox?

Thank you for
your question Ida1982. I understand your concern. Botox is a purified
protein used to address wrinkles associated with facial expression. Botox has not been shown to be associated with hair loss. However, many conditions are associated with hair loss. If I had a patient who experienced hair loss after an illness that required hospitalization I would say that the illness was the most likely cause of the hair loss.
Please
consult with a doctor for specific recommendations. Good luck!

Botox doesn't spread. It only affects the local area where it is injected. It sounds as if you have some other condition that is causing the flu like symptoms and the hair loss. I would suggest that you see your physician for a full work up. Best of luck.

The hair loss you are experiencing is likely associated with your systemic condition for which you were hospitalized and unrelated to Botox.  Botox causes relaxation of the muscles, which results in smoothening of the overlying skin surface.  Hair growth is unaffected.  

Thank you for your question.  It sounds like you had something else going on that was coincidental to your botox treatment.  I have never heard of botox causing hair loss or systemic illness, it stays localized in the muscle.  

Hi there (from NYC),
   Botox should not cause any form of hair loss, not short term nor long term.  Further, Botox does not cause systemic reactions in quantities used for cosmetic/medical purposes.  Your symptoms are likely attributable to something else, possibly a systemic viral infection, which should be self-limiting.  If your symptoms worsen, I would consult your PCP or a local Emergency Department.
