Weighing in here...
Bern, congrats on the home stretch! The boost should be easier, it just targets the area where the tumor was, so the other area won't get any more rads. Whew!
My hair never came in with white cat fuzz, just came in the same. I always had curly hair and when it was an inch or so, the wave started. One word: Mousse! I started with it as soon as I could make it look like a style. Getting dressed was a great treat in the morning...mousse and go! I finished rads in APril, went topless in July and got my first haircut in December. Just a tiny trim, to even the ends and give it shape.
Today, 6 years later, you'd never know.
And Bern, 6 years later, my rad breast is still sore. Most of the time I do not notice it, but when pressure is applied (hugging, laying on the floor, when my dog climbs on me...). To a gentle touch, the skin is normal and soft. The tissue is firmer though, one of those lasting gifts...
Hooray for the home stretch!
