I understand the fear of everyone looking at you while outside when bald, but it can also be a nice kind of experience. Due to the hot flushes and sweats from chemo I couldn't stand to wear anything on my head. So bald when out and about it was. I was very aware of people around me and never got any uncomfortable looks. What I did get was kind comments from people who had been there and done that ie former chemo patients who were nice and incredibly supportive. In fact in the end my baldness made me feel like part of a club. Just wanted to let you know it can be a great way to meet nice people who fill you with hope and inspiration. Have a great trip.
