I've been blogging and tweeting about my experience in treatment for breast cancer, including what it's like to go through chemotherapy. The chemo drugs I received made all my hair fall out (not all kinds do, but mine did). I've been going around "commando," as people with cancer say—bald, no wigs. Scarves or hats only when it's too cold or sunny to go bare.
You do whatever works for you to get through this. Going around bare-headed is what works for me.
If you know a woman or girl receiving chemotherapy, maybe you'd like to share this with them, too. Good days always follow the bad.
