A couple months ago I decided to ombre my hair myself. It was a spur of the moment, impulse decision, and I am so glad that I did it! By now, it has faded a bit, but that's how I like it; I wanted it to be a more natural look! Definitely more affordable than going to a salon, and you really can't tell the difference.
I used this Revlon Highlighting Kit for about $10 from my local drugstore. I would recommend something like this over creating your own bleach solution at home because it will definitely cause less damage to your hair! Looking back on it now, I really regret not taking any pictures, but I'll try to describe it as best as I can! Read the step by step instructions below:
[What You'll Need]
Robe or old towel
Prep your hair according to the directions in your highlighting kit and drape the towel/robe over your shoulders to keep the dye off your clothes.
Use the supplies in your kit to paint the very ends (I did about 1.5 inches). Make sure you get really good coverage of your hair and then leave in as long as the directions tell you to. I also put my hair in foil just to keep the dye/paste from getting everywhere.
Repeat step two but with a larger section of hair. I did this about three times, each time covering more hair just to make sure that it looked gradual. I only took my ombre to just below my chin, but I have really long hair. It's all up to you!
Even a highlighting kit over a homemade bleaching solution will still damage your hair, so make sure that you have a really good conditioner you can wash your hair with. My hair is no longer that damaged anymore, but it was pretty bad for the first week or two.
Also, you might want to get some shampoo and conditioner for color-treated hair because my color did fade after a while. That's all there is to it! I looked at a bunch of different DIY's and many of them seemed extremely complicated, so I thought I'd just wing it and make up my own, more direct way, and it worked extremely well!
If you have any questions or if any of the directions are unclear just let me know and I'll be sure to help you out! Here's a good look at how my ombre looks after a few months.
