Rated 5 out of 5 by from Great shade Thank you BzzAgent and L'Oréal for the free sample! This is the perfect shade to tone bleached hair with. Easy to use and turns out beautiful!

Rated 5 out of 5 by from Will definitely keep this on hand I put this on a client after we did a root retouch. Her hair had a lot of vibrancy and felt so amazing.

Rated 5 out of 5 by from I absolutely loved this product! This color line is used like any other color like even though L'Oréal was one of the first professional lines it's often thought of as a "box color" so it's passed by but I can attest this line stands up just fine next to other lines I loved the shine and condition of hair after using.

Rated 5 out of 5 by from Love this product ! I used this toner on a level 9 client and loved the tone! Gave such beautiful shine to the hair! I also really liked the consistency of the product. I will definitely re purchase.

Rated 5 out of 5 by from I would use this again The L'Oréal DIA light ammonia-free Demi-permanent gel cream haircolor mixed fabulously. There was no overwhelming scent. It applies easily with a brush and bowl application. The coverage was flawless. The client had zero complaints while processing. It rinsed easily, and the hair was manageable. The color was absolutely beautiful. It wasn't flat, and it almost had reflective properties. The client was thrilled with the end results. I will definitely be trying other colors in this line after seeing how amazing this worked.

Rated 4 out of 5 by from Shine! I used this product by itself. Using the clear tube and developer added that extra special touch to my hair. It looks so glossy and fresh.
Date published: 2024-02-26
Rated 4 out of 5 by from Not my favorite I have been struggling to find a good toner that doesn't take 20 minutes to process. I'm well educated in European lines as well as American and understand the level scale and measurements. However, this product was a pain to measure and use plus had minimal results after 15 minutes (I gave up because ill never use a 20 minute toner). Definitely has great shine and I'm supposed to be reviewing "clear" which is clear but I'm sure a review should be based off of other shade; which I purchased on my own. I used 2 parts 9/21 and 1 part clear on prelightened level 10. Softened the harshness and left the hair soft, closed the cuticle, and didnt bust the base, but I've had better and faster. I miss Pulp Riot liquid toners!

Rated 5 out of 5 by from Beautiful color! Wow, this is such a beautiful color. It is easy to apply, and leaves hair feeling nice. This is a great product to keep on hand in the salon. I highly recommend trying on your clients that want to be super blonde. This color is flawless!
Date published: 2024-02-23
Rated 5 out of 5 by from My personal color! I love this color because it is the one I use on my own roots. It is a gorgeous, toned, blonde, true blonde beautiful.
Date published: 2024-02-23
Rated 5 out of 5 by from Great Toner For a level 8 -10 it is amazing! For level 8-9 it helps tone the hair to be even, and helps with making an even tone. For a level 9-10 it will make it a beautiful opalescent or white formula! I will say depending on the starting base of the client will vary upon the result that you get. If you have a warmer base client, it will neutralize it. If they have cooler base it will come out a bit brighter and whiter.

Rated 5 out of 5 by from I am in love with this color product! I was a bit skeptical when I initially got this color cream. For one it used such a low developer that it just didn't seem like it would process the way it needed to. I haven't had much good luck with clear glosses. I just don't feel like they do much for the client. I went ahead and tried this one anyway. I swear my clients hair felt AMAZING. The demention and shine was unbelievable! It just looked so much healthier, there were no tangles or knots at all and she walked out feeling like a million bucks. This is going to be something I keep on my salon on a regular basis and recommend to all of my clients that don't want a full color but Want a pick me up on dull hair. This is the best gloss I have ever used, hands down!

Rated 5 out of 5 by from Love love love dialight Dialight is one of my go-to toners. Not only does it give the most gorgeous color, or in this case of clear, a gorgeous shine, but it leaves the hair feeling super soft and smooth. I prefer to use this over the super popular liquid toner line.
Date published: 2024-02-23
Rated 5 out of 5 by from Beautiful color Sampling product in exchange for a review. This is a beautiful color, rich and creamy. No harsh smells easy to apply.

Rated 5 out of 5 by from My fave toners I've used dialight for years and will continue. The most true to tone toners and they last way longer than other popular toners like shades.

Rated 5 out of 5 by from Now a staple in my color cabinet I was sent this product by L'Oréal Professional in exchange for my honest review. I tried this toner on a client who always comes back for her 8 week appointment super brassy no matter what I do. I typically have to do some major work on her ends every single time. I thought I would try just applying this toner without doing much on her ends to see if it would give me the results I needed, and this toner not only made her hair super shiny, but it also go rid of all of that unwanted brass she struggles with. Usually I have to do multiple steps to get the outcome she is wanting, but not this time. I was able to tone her with 1 toner which cut her appointment time down tremendously. This product is now a staple in my color cabinet. Thanks L'Oréal for the product!

Rated 5 out of 5 by from Works great! So iv been wanting to try these and I was so glad to receive this sample. The consistency of this color is amazing I loved it the tone was beautiful and I think I'm going to start using this line since I have been looking for other options
Date published: 2024-02-21
Rated 5 out of 5 by from Very nice I haven't really used this color line before, so I wasn't sure what to expect. As a gloss, this left the hair remarkable soft and shiny. Definitely a great add on service. I would be interested to explore more of this color line!
Date published: 2024-02-21
Rated 5 out of 5 by from Amazing results I really loved the results I got from using this product. I also love that it is ammonia free. This product toned my clients blonde hair perfectly and gave her a very pretty icy blonde. It also left the hair extremely shiny! Will be using this in the future.

Rated 4 out of 5 by from Healthy option for hair color I really like this product for blending and adding tone. It is mostly acidic based so very gentle on the hair. The tone is pretty and was great foe blending roots and brightening past highlights. Only con is it washes out so the longevity is much less then a permanent color. Overall a great option for semi/demi color

Rated 5 out of 5 by from Beautiful! This 10.21/BV is so beautiful! It's a perfect shade to tone & gloss a bright blonde. I love the consistency because it's easy to have an a precise application. My clients hair was SHINY after using this. Definitely recommend
