Hair Advice Needed

Hey guys!

So I need some advice on what to do with my hair. Lately I have not been that happy with my hair.  I LOVE it when I first get it done, but the brown fades SO fast and starts to turn brassy and almost red.

Just some background for you guys : My natural color is a light brown.  I started getting highlights when I was in high school. I started with subtle blonde highlights (that were hardly even noticeable!) and gradually went lighter and lighter until I was eventually platinum blonde.  I had platinum blonde hair all through college and for about 10 years after I graduated from college.

About 2 years ago, I felt I was in need of a change and decided to get it colored dark brown.  Everyone told me it would be so much easier to keep up with than the blonde, but that hasn’t been the case at all. I don’t know if it is just because my hair was blonde for so long that it just doesn’t want to hold the darker color? Over the last 2 years, I have been able to hold the brown a little better over time, but within 2 weeks or so, the brown turns very brassy (while the blonde holds perfectly and still looks like it was just colored even after 5 weeks!). My hairstylist said my hair obviously just has a mind of its own and wants to be super blonde. 🙂

I have liked having my hair colored dark brown with thick blonde highlights because I feel like I get the best of both worlds and don’t have to make a decision to be one color or the other, but being that the brown does not hold very well, I am torn if I want to stay with this style or make a change.

So this is where you guys come in .. Do you have any (much needed) advice for me?

Here are a few pictures of me as a blonde :





Here are some recent pictures of me with brown hair and blonde highlights :





One idea I had is to stay with the brown as a base, but add a lot more blonde highlights (and maybe it will not look as brassy?). I found this picture as an example:



Help me!!!  What color do you think suits me better?


Thank you in advance for any advice you may have! 🙂
