Rated 4 out of 5 by from Great coverage & lots of shine! I liked the new product. It mixed well & I like that the ratio gives more product than before. It works beautifully for lowlights and root smudges. It gave the hair so much shine!! I am shocked at how well it covered greys!! I am bummed that it shifts the natural base and doesn’t just deposit. I am also bummed that it doesn’t have all the same shades as cover plus. But I love having something new to use behind the chair!

Rated 4 out of 5 by from Color is nice. Does feel a little dry after coloring. I will say, it did last longer in the hair before fading than some other colors that I have tried.

Rated 5 out of 5 by from Loved these!! Shades ALK 5N and 6N Alkaline Demi Hair Color provided a very natural-looking neutral brunette with beautiful shine. It was smooth and went on evenly, making it a great quick color refresh. The final look was glossy and a little dimensional. Loved these!!

Rated 5 out of 5 by from Good upgrade when needed for blending grey Nice upgrade for Shades Demi line. Gives you the grey coverage we all desire in a little thicker formula which is also a bonus. Little more opaque as well. Def worth a try.

Rated 5 out of 5 by from Perfect brunette refresh Loved working with Shades ALK 5N and 6N Alkaline Demi Hair Color. Both shades produced a very natural-looking neutral brunette with beautiful shine. The formula applied smoothly and saturated the hair evenly, making it easy to work through mids and ends for a quick color refresh. The final result looked dimensional and glossy, and the hair felt soft after rinsing. These shades are great for toning, refreshing faded brunette color, or blending early grays without going too dark. Overall, it’s a reliable demi formula that gives consistent, natural results behind the chair.

Rated 4 out of 5 by from Great Professional Demi Color As a stylist, I’ve had a really positive experience using Shades ALK Alkaline Demi in the salon. The formula is easy to work with, has a smooth consistency, and applies evenly through the hair. It processes predictably and leaves the hair looking shiny, soft, and healthy, which clients always notice. I also appreciate that it provides reliable gray blending while still maintaining the gentle feel you want from a demi-permanent color. The color results are vibrant and true to tone, and it’s a great option for refreshing faded color, toning, or enhancing natural shades without committing to permanent color. It’s been a nice addition to my color line for clients who want dimension and shine with minimal damage. The only reason I’m giving it four stars instead of five is that I would love to see more shade selections and undertone options added to the line. A wider range would make it even easier to customize formulas and create more tailored results behind the chair. Overall, it’s a dependable demi-permanent color that performs well in a professional setting, and I look forward to seeing the shade range continue to expand.

Rated 5 out of 5 by from I love Shades ALK! I love love love using the new redken shades ALK line. I was given samples of 5N and 6N and loved the shine it gave my clients hair while also giving nice coverage on their natural grey hairs. I was surprised that were was no scent and it’s made with the cleanest ingredients. This product is perfect for clients with a ppd allergy and I will be grabbing these for future color appointments!

Rated 4 out of 5 by from Shiny glossy I received this 5N and 6N to review through bzzagent. I only had a chance to use 5N and hair was glossy with decent coverage for a Demi…I can’t speak on fading since not enough time has gone by but I’ll report back.

Rated 5 out of 5 by from Nice! Really nice Demi color. Good coverage, very mild scent, and mixes and spreads easily. True to tone.

Rated 5 out of 5 by from great coverage for a demi While Redken is not my main color line, I am a huge fan of shades so I am very happy to have received samples to try. I tested the 5N and 6N which are my two most common used levels. Some pros: very shiny, glossy finish, hair feels softer and healthier after, good gray blending/coverage without permanent committment, demi fades gradually without harsh regrowth. I did have one client say it faded quicker than usual, but that could be user error based on how she washes her hair.

Rated 5 out of 5 by from PERFECT This is the ultimate secret weapon for achieving that expensive, high-gloss brunette. I’ve been using the 5N and 6N for root smudges and gray blending, and the results are consistently flawless.

Rated 5 out of 5 by from Great gray coverage! Beautiful color payoff! I have a ton if grays as well as my clients and the gray coverage is phenomenal! Consistency is creamy and easy to work with and didn't have a strong smell which is great!

Rated 5 out of 5 by from A must have! If you’re looking for a demi that truly performs, the new Redken Alkaline Demi Permanent Haircolor is a game changer! The alkaline technology makes a noticeable difference in gray blending and coverage. Unlike traditional acidic demis that simply deposit, this formula allows for better cuticle opening and deeper dye penetration giving you surprisingly strong gray coverage for a demi. On resistant or coarse gray hair, it grabs evenly and leaves a soft, natural-looking result without that overly flat, opaque coverage. The formula is super easy to work with, offers great results and has definitely become a staple at my back bar!

Date published: 2026-03-05
Rated 5 out of 5 by from Super impressed. I received a sample of this product in a 6N and a 5N. I first used the 6N on a natural level 6 that had been highlighted but had grown out for 5 months. I couldn’t believe how rich and shiny it looked when done. After these results I couldn’t wait to try the level 5. This one I used to deepen a natural level 5/6 that had been highlighted. She wanted to darken the underneath and add a few lowlights. This product took so evenly. Again, so impressed with the richness and shine. Definitely will be getting more of these in my collection.

FAQs

A: More than ever, hair color clients are looking for the secret to healthier looking hair . They don’t only want to conceal their first grays, they also expect shine, hair that feels hydrated and has vitality with restored movement and bounce. Shades ALK provides all of these benefits plus a lower commitment than permanent hair color by offering an easy transition with grow-out compared to a full coverage permanent color.

A:  Shades ALK has 1-level lift vs. 2-level lift from a traditional permanent color, and it features colored coverage vs. full coverage.

A: To cover gray means to minimize the contrast between natural hair and gray hair. To what degree that contrast is minimized is the difference between coverage that is translucent to coverage that is opaque and everything in-between. Shades ALK provides colored coverage, with superior performance with N, NA, NCh, NB, GI shades.

  • a. Use N, NA, NCh, NB, GI shades for up to 75% gray coverage
  • b.    Use VG, AG, G, and CB shades for up to 50% gray coverage
  • c.     Reflective shades C, R, and RV will provide colored coverage depending on their level of deposit
  • d.    Cool shades T, AB, P and V will provide coverage depending on their level of deposit, for example lighter levels 9-10 will not provide coverage, but deeper levels can. Lighter levels may appear more blended.

A: Shades ALK N, NA, NCh, NB and GI shades have been formulated to provide up to 75% gray coverage when mixed with 10 volume. They have not been validated for use with higher levels of developer. If you are looking for more coverage or prefer to use 20 volume, we recommend using a permanent haircolor such as Color Gels Oils.

A: The 1:1.5 mix ratio ensures a product consistency that is creamy and thick, yet easy to apply with bowl & brush and bottle and to pull through the ends. Additionally, it provides the optimal rate of dye oxidation and up to 75% coverage within the 20 minute development time for robust, saturated results.

A: We are super excited to offer 50 unique Shades ALK shades at launch, but we understand that it may be overwhelming to take in all at once. We recommend taking a handful of shades from each of our tonal families to ensure you have everything you need to get started with your clients:

  • a.     NATURAL: 4N, 5N, 6N, 7N, 8N, 9N, 5NCh, 7NCh, 1NA, 4NA, 6NA, 8NA
  • b.    WARM: 7GI, 9GI, 4G, 6G, 8G
  • c.     COOL: 8P, 10P, 6V, 9V, 6AB, 8AB
  • d.    RED: 10C, 7C, 6R, 4R, 6RV, 4RV
  • e.     CLEAR
