This product did nothing at all. It did not tint my hair even the slightest bit. I wasted $20 for nothing! If I could give it zero stars I would.
From oVertone Color team
We’re sorry the color wasn’t visible on your hair. oVertone is a semi-permanent color-depositing product, so results can vary significantly based on your starting hair color, porosity, and existing color. Darker or less porous hair may show little to no visible change, while lighter or more porous hair typically shows more noticeable results.

Not recommended, turn my hair blue
This product is a really good conditioner, leaves your hair very soft. For the color didn’t do anything to my grays; I have dark brown, black hair with lots of grays and some decoration that were orange so decided to give it a try since I been not dying my hair for a few months. It took away some of the orange but gave me blue reflections with the light and make my white hair whiter. Definitely not recommended
From oVertone Color team
Thanks for sharing your experience! 💜 We’re glad to hear your hair felt soft and conditioned, but we’re sorry the color result wasn’t what you expected. oVertone can behave differently across varying starting shades, especially with gray, white, and previously lightened hair, which can accept pigment differently. We appreciate your detailed feedback on the orange and blue tones you experienced and will pass it along to our team.

Great!
I use this to touch up my hair (i dyed my hair black from brown) it costs like 120 dollars to touch up at my hair salon. This is easy, didn’t stain my bath tub, and I like the results. I usually reapply every 3 weeks.

Didn’t cover any of my grays! I got black velvet and made my grays bluish!
From oVertone Color team
We’re sorry to hear Black Velvet didn’t give you the result you were hoping for. On gray or white hair, cooler black shades can sometimes pull blue-toned since there’s no underlying warmth in the hair to balance the pigment. Our semi-permanent colors also work more as a stain/tint on grays rather than permanent gray coverage. We appreciate the feedback and will share it with our team.

Will not purchase again.
Never write reviews but this product didn’t even hold 24hours through the wash out. Followed all directions. Just stuck to my scalp not my hair. Will not purchase again.

We’re so sorry to hear the color didn’t take as expected on your hair. Results can vary based on starting shade and hair condition, but we appreciate you sharing your experience and will pass this along to our product team for further review.

Covers my grey hair wonderfully!
This deep purple covers my grey hair very well! It comes out as a lighter purple, which I love. I will continue to use this color.

Great color deposit without damage.
I had really bad bleached hair, I finally colored it a medium brown and it was terrible, it was turning greenish. I used this today and it really gave me a beautiful dark rich brown/black it filled it in nicely. I have tough grays it helped a bit and definitely covered some but I'm going to treat the roots only more frequently. It left it so soft and more natural looking. I was able to straighten it with no problems. It gave me a much healthier looking color. I really think this is going to be my product.

Saves me a trip to the salon
I love stormy sterling color depositing treatment mask. I was spending money monthly going for a mask at the salon and this color matches perfectly for a fraction of the price! My hair is soft and the color is perfect.

Formula changes
The formula has changed. I like that it is thinner, but the color isn't a vibrant as it was before and didn't cover my silver as well as before.

Amazing for Refreshing Professional Color
I started using Overtone at the reccomendation of my hair stylist to keep my color refreshed in between appointments. Ive been using the color depositing mask for each color I've gotten and I've been very impressed with how well it maintains my professional color!

Beautiful Blue!
Bought at Sally beauty Supply, I previously had a dark red that was fading and wanted something different I bleached out the remaining red and put this over it and wow! My hair feels healthy and is so shiny after using this, just make sure you wipe it off your neck and ears quickly to avoid staining

The best pink in the business!
This color mixes really well with others-- I've gotten a vibrant magenta with it alone, a light pink, and mixed it with blue to make a lovely medium purple!

On gray it turns purple
A nice purple! And it's not like Overtone claims it works on grays. But close up, it's very purple.

No More Brassy Yellow
I received this in the sampler pack for gray/ silver hair. I didn't want purple hair but didn't want to waste this shade either so I mixed it with 2 parts Stormy Sterling with 1 part pastel purple and it gave me the natural shade I was hoping for and covered the brassy yellow that I had. The added plus it that it's a conditioner so you get the benefit of color without the dryness caused by harsh chemicals in permanent hair color. My hair is super dry naturally so anything that makes it look shiny and healthier is much appreciated. I attached before and y pictures..it obvious which is which..lol

Used to love this
I've been a tried and true overtone customer for years, and I would always get their emerald green color depositing conditioner. it gave me the perfect color, kept my hair healthy, made me happy, etc. when they replaced it with this, I went ahead and bought it, thinking it would be a similar experience. that was unfortunately not the case. a big reason why I bought the green conditioner from overtone was because it had a yellow base for the color, not a blue base. I absolutely hate blue in my hair; it doesn't look good. so it was disheartening to use this in my hair today to find that the base is now blue. It's a big enough deal to me to make me wanna switch to a different dye somewhere else; but overtone still has amazing products, my personal experience just wasn't what it used to be.

Not too orange
Loved how this came out! Used the Overtone bleach on it first and I do a section in the front right part. I usually do the red so I was very nervous. However, I am pale in the cooler months and tan in the summer so I love how the red in better for the summer and this one is better for my skin tone in the cooler months.

Love this color for my natural grey hair
It is so nourishing for my scalp and I love the color. I have natural grey hair and I use this to tone my hair. I am also allergic to hair dye, but this brand is the only brand that doesn't give me an allergic reaction. Best color for grey hair and also if you are growing out your greys and need a little help with the transition.
