Home-made "ombre"?!

Hi guys!!!

About a year ago I read the word "ombre" in fashion magazines for the first time. They used it for pants, tops, nails and even hair!  That's when I started my research to discover it's meaning was just combining two colors and making them look like they are both melting together in the middle.  The first ombre thing I had was a pair of tights (see below), melting together blue with gray.  

 My new curiosity is trying the ombre trend on my hair.  I think this is a very scary/risky/daring adventure, but I'm suddenly tired and bored of my hairstyle.   As many of you know, I've been using a dark-reddish brown color in my hair for months and I need a change.  L'oreal launched the new: Les Ombrés by Préférence (see below).  I've been thinking about buying the Ombré N.1, which is the darkest one.

My hair is short/medium right now, 
so the final look I'm expecting is something like this one:

I have mixed feelings, since I'm so excited and terrified at the same time.  My plans are to wear this look for summer, so I'll put this plan in action by the end of May and, of course, will make a post about my experience.

Would you try this home-made ombre 
or would you prefer the help of an expert?

Have an awesome weekend!
