Hi Carrie
I had mine done after Chemo so can’t comment to the side affects.
The process itself was only mildly uncomfortable and stings for a bit after. I needed a touch up about 6 weeks after. Absolutely love them and so glad I did it.
My practitioner needed a letter from my oncologist stating the treatment was ok (even though I was finished treatment).
Have you been offered “cold cap” for your hair. I didn’t take the option but several ladies on the oncology ward were having great success with hair retention. Worth raising the question
Good luck with the brows and the treatment
