Could the Botox injections for my migraines cause 2 sections of hair to not curl at all?

I am a 57 year old Caucasian female with no noticeable hair loss other than thinning eyebrows and eyelashes; most likely related to my hypothyroid, which is being treated. I have had 2 sets of Botox injections focusing on the left side and the nape of my head more than other areas. Injections were administered to the brow, both temples, and crown of the head. I did not experience this problem after my first set of Botox injections.
