I might say, "Hey, how do you think I'd look as a blonde/brunette/redhead?" (BTW, I've tried them all.) But I usually make major changes on a whim. When DS7 was a baby, I went to the salon with long, brown hair and came back with it short and blonde.
I'm currently single, but thinking back to all the guys I've dated - I would probably ask their opinions and end up being talked out of it. Maybe it's just the ones I've dated, but I feel like most men don't deal with physical change too well. If you want to make the change then make yourself happy and just do it, and they'll just learn to adjust. I made a fairly drastic change in my hair this year and it went very well. I hope you decide to make whatever change you're looking to make. Remember: hair grows back and can always be redyed.
Thanks. I'm generally not very adventurous with my hair, though I was more so when I younger. I also know that some guys don't like short hair.

I have been blonde for a long time. Then, earlier today, I went to the salon and I'm now a dark chestnut. I love it! DH is not real thrilled b/c he thinks it is red and he doesn't like red hair. I told him that I was changing it, asked his opinion ("Whatever, just not red.") and went to the salon. I also know that he doesn't like it short. However, I have had it short and I liked it. I try to keep him happy, but I do it how I want it too.
Yup. I need to get my hair cut shorter by the time the baby comes. DH doesn't like short hair, so I will probably do a little past the shoulders. It is currently at my waist.
Congratulations! When are you due?
We are super excited.
