I haven't been around much of late, but I had to respond.
Welcome to SBG, a great community here. I have also faced cancer, and the chemo hair loss was the push I needed to shave the rest of my hair off. I beat the cancer, and ended up loving the shaved dome so much that I keep shaving to this day, nine years later.
Keep a positive attitude, and you can beat this. Prayers with you!
