Love it

I love this product, it doesn't make my hair dry or uneven color, on the contrary it makes it really soft and the color is so vibrant for way longer time, so it saves me a lot of money on retouching and time too, since it just needs half an hour.

Love! Love! Love!

Okay, at first I was chicken. I let my ‘brown hair’ grow out and had natural hair with grey. Talk about boring! So, I tried Overtone. But I was (admittedly) a bit tentative and tried the pastel. After working with the fantastic customer care department I went to Extreme. Have I said LOVE? I can’t even tell you how many people have stopped me to tell me that they love the color. In Iceland I was stopped by a waitress, a hotel receptionist and even a fellow hiker on the glacier! At home my plumber (yup, I said plumber) commented and a sales woman in a sporting goods store asked what I use as well as a woman who stopped me in the mall today. Don’t be scared! Go for it!

The conditioner has made my hair soft and healthy.

Color Game Changer

Overtone Extreme Blue has been a Life-saver for my blue balayage highlighted hair! It's been over 7 months since my last professional dye and I still have vibrant color thanks to this deep treatment and the conditioner. I have very dry ends so this deep conditioner nourishes while it colors. It also smells great!

As stated in the directions, you'll get the best and brightest results when used on dry hair and left on for 15 minutes. When I've been in a rush I've conditioned in the shower for about 10 minutes and I still get a good glow, just not nearly as bright so you might as well stick to the conditioner in the shower and the deep treatment 1-2 times a week, if you can spare. It leaves my hair refreshed and I'm going to keep putting off that next dye for as long as possible!

PERFECT OVER NATURAL GRAY

My hair is thin and fragile so I cannot bleach it. I have been using henna for 5 years so the henna is absorbed is most of my hair except for the gray coming in at the roots. In this pic I used extreme blue (it came out purple) and it only covers the gray. I love it. I recommend overtone for people with gray and white hair. I am now experimenting with combinations of color and posting other reviews for other colors.
