Absolutely change your photos to your bald look. I periodically grow my hair to a short flattop, so I was changing photos alot. Now I just leave my shaved head photos online, as I usually don't grow hair more than a month or so. After about a week, I break out in a bad dermatitis issue. As soon as I shave, it's gone in about 3 days. Even though I have a full head of hair, I guess mother nature has determined I should remain bald.
