LOL! I LOVE your attitude!! I have always wanted a mohawk too and now that my hair is coming back in, that's exactly what I have. I shaved mine off before chemo with a group of friends (yes, there were adult beverages involved) and it was liberating. By the time it actually started to come out I was ready.
That you are meeting your possible future in-laws with your new do is hilarious. I would love to see the look on their faces. You may want to consider leather pants and a spiked collar to complete the look. Personally, if someone I was meeting for the first time was rockin' some funky hair we would be fast friends. They are going to love you and secretly wish they had the nerve to do the same thing!! Forget blaming it on chemo brain....YOU OWN IT GIRL!!!!
