Love Overtone!

I use the deep conditioning treatment every few months or so to really refresh the color. It’s like I’ve just dyed it. I have a lot of hair, so it takes the whole jar to cover all of it, but it’s so worth it. That’s also why I only use it every once in a while. But I just saturate my whole head and leave it on all day and rinse it out at night. And my hair is gorgeous and soft and the color is perfect.

Easy to use, but does stain a bit

Beautiful deep blue with violet tones. It shows up really well on my hair without bleaching. It does stain a little, so wear gloves. It's a great alternative to frequent salon visits for maintaining color, and this is one of the better blues that I've seen. The deep treatment lasts quite a while, too.

It works on grey hair!!

My roots are almost totally grey. I've experienced some difficulties with hair color covering my grays. The Overtone deep conditioner vibrant blue covered all my gray. And it was bright! Wild! It lasted a long time - one month on the side and I still have color on the top and it's been over 2 months. I left the product on my hair longer than recommended. I put a plastic bag over my hair and left it in for an hour. When it began to wear off it resembled highlights on the sides of my head. I have had one application and no daily spray.. I believe the difference with how long the color lasts, is because the sides are manipulated more in styling and when I sleep The only downside, the deep conditioner really didn't soften and moisturized my hair. Also, it took a long time to receive it after I ordered. Shipping is slow

Blue Smurf life

Purple faded to pink then faded out but still had some pink areas . Added the deep blue and oh man came out so pretty with a hint of purple in the spots where the pink was ... now every time I wash it more purple comes out from under the blue . I’m super happy with it
