Ombre Hairstyle

The ombre technique is used on pretty much anything you can think of including clothing, make-up, nails and hair. I've wanted to do a conservative ombre hairstyle (similar to the photos above though now that my hair is a lot shorter I might have to wait a while) for the past few months. I checked with one place to see how much it would be and plan to call a few others but if the price is anything like the first salon, it won't be happening anytime soon. A co-worker of mine told me they have hair-kits now where you supposedly can achieve the ombre look yourself. I found Feria Wild Ombre by L'Oreal Paris and though creative, it doesn't look promising. I watched this demonstration and didn't feel confident enough in the product. I feel like even if you had someone to help you it could end up badly (what if it didn't look properly blended?). What do you ladies think? Would you try something like this yourself? How much have you heard an ombre hairstyle costs? Is there a hairstyle you've been wanting lately?
