Not everyone reacts to chemotherapy the same way and it also depends on the type of chemo you are having. I did not lose my eyebrows or eyelashes although they did become thinner. However, I did lose all of the hair on my head, under my arms and in my public area. I did not lose the hair on my legs or arms. All of the hair grew back except for the hair under my arms. I have not had to shave under my arms since I had chemo. : ) My chemo was AC and I didn't have radiation. I hope all goes well with your treatment.
My hair all came out. Eyebrows and eyelashes too! Leg, arm, pubic and pits too! It was an interesting look, to be sure!
I didn't mind the "bald" look and never wore a hat or wig or scarf. I did miss the eyelashes though since every piece of dirt flew into my eyes!
It's not such a big deal though and you'll do fine :)
Best wishes with your treatment, and let us know how you're doing!
