Although I really like your previous look. The blonde look good, however, I would recommend ditching the first image in your port. Your hair looks damaged in that image. I can tell from your other blonde images that this is not the case, but that image is not flattering to your hair at all.
I prefer your first look as well but that doesn't mean either one is better than the other. So long as you feel better after your augmentation then that's what matters.
Agree with all the rest about getting rid of the first picture, you could curl your hair and re-do the picture like that and it would look gorgeous but the messy look does turn out damaged with that much back light.
Regardless of look you are a good model and can probably pull off whatever hair color or look you want.
I agree with the other posters on the first image, it does not flatter your hair. However, the concept and pose, your expression and details (such as the shape of the nipples through the fabric) are very appealing. Maybe you could try to redo it and ask the photographer to raise the back light so as to not shine the light through your neck, but rather having a sort of aura around the upper part of your head.
I liked the blue hair look pre-augmentation. I honestly was scared looking at the new ones but great job by the doc keeping it natural looking still. You have a nice range and the blonde works and the classy look you want is easily pulled off. I agree about the first pic as others have mentioned. For me it is the make up. Kind of look "sickly" with the way the eyes are made up. You are truly a beautiful woman and working with some good people overall. Great job.
