Will Botox trigger inflammation and cause hair loss?

There is no known link between Botox treatments and hair loss. You should be fine to proceed as planned. If you are uncomfortable you can elect to wait until you have fully recovered from the inflammatory reaction you had to the Covid vaccine.

Traction alopecia is a result of hair follicle trauma usually from someone pulling on the hair or from very tight braids. Alopecia may also result from increased stress. I would recommend seeing a board-certified or board-eligible plastic surgeon or board-certified dermatologist regarding your hair loss.

If anything Botox injected to the scalp can stimulate hair growth by relaxing the small muscles surrounding the hair follicles. Botox injected to the face should have no detrimental effects of hair loss or an increase in inflammation. Best of luck!
