Rated 4 out of 5 by from Pleased enough to try again! The consistency is creamy and easy to mix. The coverage for grey is perfect. It smells very good and left the hair very shiny and manageable. I'm going to try other colors as I felt these colors (6N and 6GRv) were muted just a little bit. Overall, happy with the product for a demi 😁

Rated 4 out of 5 by from True to tone. I really like the formulation for these and I feel like the color description is true to tone. My only complaint is that they are a tiny bit hard to spread through to get every hair strand evenly during an all over color.. its a little thick I guess I would say compared to my normal color line.

Rated 5 out of 5 by from Beautiful Results with Easy-to-Use Demi-Permanent had the opportunity to try L’Oréal’s Professional Dia Color in Shades 6 and 6.35, and I was really impressed. The creamy, pliable consistency made it easy to mix and apply, and the light, pleasant scent was a bonus. Both shades delivered beautiful, true-to-color results with great grey coverage, leaving the hair soft, shiny, and manageable. As a demi-permanent color, it performed really well, and I’m definitely planning to try more shades in the future.

Rated 4 out of 5 by from Didn't love results - will try again I received this product in exchange for an honest review. I've been looking for a new cream demi-permanent line to use, and I was excited to try this. I used it as a toner after balayage, and I didn't love it. The tone was lacking, but it might've just needed more time to process. I'll give this line another shot, because I've been happy with L'Oreal color in the past.

Rated 1 out of 5 by from love this line over all but… The 6.60/6RR has stained multiple clients sheets, towels and shirts. Love the color but it doesn’t hold and has cost me money to refund clients hair color. Over all the line as a whole has great grey coverage, blending. N shades are true neutrals and fade beautiful

Rated 5 out of 5 by from I love Dia! Ive been using for ten years now from Dia Richesse (rip) to Dia Color. I do miss Richesse but still love Dia Color. L’oreal is the best.

Rated 4 out of 5 by from Nice coverage and color reflect I can’t attest to the longevity yet, but the coverage is very good. The reflect is nice, and it seems pretty gentle on my fragile hair. No bad smell at all which is a huge bonus for me.

Rated 5 out of 5 by from Nice Demi! I usually use Redken Shades, but after trying this line, I’m truly impressed with the shiny, true to tone results. The hair feels healthier, and the consistency made it easy to apply. I would definitely use it again!

Rated 5 out of 5 by from Would use again! This product was given to me for an honest review. The consistency of it was nice and creamy. Application was easy. The results seemed pretty true to shade and super shiny. All in all I’d use this again.

Rated 4 out of 5 by from Nice Demi-Permanent Color I had the opportunity to try L'Oreal's Professional Dia Color in Shade 6 and Shade 6.35.  It has a very light aroma and the consistency is very pliable, easy to mix.  The results were beautiful, the shades was true to color, very shiny, and soft.  I would use this again for a demi-permanent.

Rated 5 out of 5 by from Go to line for 95% of my color clients My absolute favorite semi. Perfect for clients that love seasonal change. I love the color selection and vibrancy, but also the way it lifts so easily. Grey coverage is great for anyone with soft or minimal grays. I received this product as a sample in return for a review, however this has been my go to color line for over a decade. This line is great for filling, low lights, reds/coppers, toning, and all over application.
Date published: 2025-05-20
Rated 4 out of 5 by from Nice for gray coverage I received as a promo to review; the overall color line is great for blending grey! Easy application process with a mixing ratio of 1:1 1/2. Smells good and leaves the hair soft and shiny.

Rated 4 out of 5 by from Beautiful Shades This color works beautifully to create a rich chocolate color. It doesn’t work as well on gray hair though works well for a simple color change.

Rated 5 out of 5 by from Just beautiful healthy hair I absolutely love this alkaline demi-permanent hair color in brunette! It delivers rich, multi-dimensional tones with incredible shine and a natural finish. The formula blends seamlessly with gray and enhances my brunette base without harsh lines or heavy commitment. My hair feels soft, healthy, and looks freshly refreshed for weeks. Perfect for anyone wanting long-lasting color with a gentle touch!

Rated 5 out of 5 by from Great Demi Coverage I’m such a fan of Demi colors and use them over permanent 90% of the time. I prefer a cream Demi to liquid bc I think it lasts longer and fades beautifully. This line has great coverage and makes the hair so shiny. The scent was pleasant and I I’m looking forward to trying other shades!

Rated 5 out of 5 by from Try it! The best Demi! I was given L’Oréal Professionnel Dia Demi- Permanent Color in 6 & 6.35 in exchange for my opinion. I've not used systems with shades and tones after the decimal before, but I'm excited to learn. I'm impressed with them so far! These demis give me more gray blending than Shades EQ. My clients have been happy with the coverage. I'm excited to try more shades.
