If You Have Color-Treated Hair, Stylists Are Begging You Not to Ignore This Product

Believe it or not, I'm someone who has only ever altered the color of their hair using natural, plant-based, and nonpermanent dyes with the guidance of my hairstylist. However, I've always been curious about the steps people take to maintain their color-treated strands after they've invested in an at-home or in-salon treatment. Are there products non-colorists can access to help with upkeep? Can the same gloss- and vibrancy-boosting products be used for all hair types and textures?

Apparently, these same questions are shared by enough people to prompt "What is hair gloss?" and "What is hair toner?" to appear as the third and sixth results when "what is hair…" is typed in the search box. It turns out that even individuals who've had their hair dyed aren't sure what toner is or why skipping out on it can be a huge mistake. If you have color-treated hair and have yet to use the product or just want to know if it can help non–color treated strands, you'll want to keep reading.

Below, find out what toner is and how to get the most out of using it and shop expert-approved product recommendations to keep your color-treated hair looking its best.

What is hair toner, and how is it used?

I tapped two colorists and stylists for their takes on the widely misunderstood product. "Hair toners are a great tool for enhancing color-treated hair—they can be used in between salon appointments to maintain the color vibrancy of your strands," explains Rita Hazan, celebrity colorist and founder of Rita Hazan Salon. They are also helpful for enhancing the overall health of your hair, specifically when it comes to repairing hair cuticles, reducing breakage, and adding eye-catching shine to the strands.

"The biggest benefit to note about toners is that they are what ties your entire color service together. When you get highlights, your stylist is using a lightener that is lifting and removing pigment from the hair. It leaves the hair in an alkaline state, therefore making it susceptible to damage if not toned," adds Adrienne Dara, a Redken global brand ambassador, hair educator, and design specialist. Put simply, adding a high-performing toner to your colorcare routine will restore hair to a healthy PH, protecting, hydrating, and smoothing your luscious locks.

Color is a false pigment that will inevitable fade, which is why it's so important to invest in regular toner services to upkeep color between your full-treatment appointments, especially for individuals sporting brown, red, and copper shades. "The pigment is stronger, and with fading comes the loss of richness. It is crucial to talk to your stylist about your one-year hair plan and how often you should be coming into the salon," Dara continues. Take this as your official sign to schedule a toning appointment before you've even left the salon after getting color.

Choosing the Best Formula

Hazan wants anyone in the market for a toner to be aware of the ingredients found in a formula. "Make sure your toner has good ingredients to prevent any damage, look for moisturizing agents such as vitamin B5 or açaí extract, and always make sure it's free of ammonia," she says. According to Hazan, it's also important to know that your hair color will fade a little with each wash. When your strands are dyed correctly, fading is subtle and completely normal. She advises staying on top of your toner schedule and discovering which products will best treat your color.

Of all the toners Dara has used, she swears by the Redken Shades EQ product line due to its acidic formulas. "The beauty of the line is that it not only deposits strong elements of hydration and moisture to the hair but one-of-a-kind color as well. With Shades EQ, stylists have the freedom to create customized colors with over 100+ series to choose from," she shares. Dara recommends only undergoing a hair toning treatment at a salon from a licensed cosmetologist but also believes that there are a few standout products to help with color upkeep at home, such as the Redken Acidic Color Gloss Treatment.

If you have color-treated hair, you're in luck! Below, I'm sharing more toner product picks from Hazan and Dara as well as a few of my favorites.
