Syoss, No. 1 in Sales for 4 Consecutive Years, Develops Color Shampoo! Easy Gray Hair Care with Your Daily Shampoo

Syoss, known for its "Syoss Color Treatment" boasting No. 1 in sales for four consecutive years*1, has newly launched a "Color Shampoo." Despite already having a top-performing product, why did the brand pursue even greater convenience? We spoke with a representative from Henkel Consumer Brands, the company behind Syoss, about the development background of the color shampoo, the formulation supporting its vibrant color payoff, and how to use it alongside their color treatment.

The Color Shampoo Market for Gray Hair Has Expanded Nearly 4-Fold

It feels like at-home gray hair care products have been increasing recently. What is the current market situation?

The market for gray hair color shampoos has grown about fourfold over the past five years (INTAGE SRI+ 2020–2025 Jan–Dec 白髪用シャンプー市場年間推移). Behind this growth are an increasing number of people caring for their hair at home due to rising prices, as well as a growing awareness of time performance ("taipa"). We feel that the desire to manage gray hair more effortlessly is growing stronger every year.

Furthermore, our survey revealed that about 58% of color treatment users have also used color shampoo, showing growing interest in using both products together in a full routine.

Why a "Shampoo"? The Next Challenge for the No. 1 Best-Selling Treatment

"Syoss Color Treatment" has been performing exceptionally well as the No. 1 seller for four consecutive years. Given that success, what was the background behind developing a new color shampoo now?

Thanks to our customers, "Syoss Color Treatment" has enjoyed widespread support. On the other hand, we have heard an increasing number of requests from people who cannot spend much time on daily care and want to manage gray hair as effortlessly as possible.

Color treatments require leaving the product on the hair for a set amount of time after application so the dye can set. In a busy daily routine, this extra step can sometimes be a hurdle. Lowering that hurdle by offering care through a daily shampoo was the starting point for developing this new product.

By simply swapping your usual shampoo with "Syoss Color Shampoo," you can lower the barrier to gray hair care by one notch, making it even easier for more people to incorporate into their routines.

"Rich Color Formulation" Blends Gray Hair Gradually with Every Use

Color shampoos and treatments are available from many brands nowadays. Why do you think Syoss is particularly favored among them?

We believe the primary strength of our flagship product, "Syoss Color Treatment," is its excellent color payoff. We are deeply committed to formulations that deliver the most crucial result for a gray hair care product: tangible, effective coloring. That is why this new color shampoo also uses a "rich color formulation" focused on achieving beautiful results. With careful attention to dye balance, color builds up gradually with every wash, naturally blending in gray hair.

Does it color hair well after just one use?

You should be able to notice a difference after a single use. However, unlike color treatments that deposit rich color in one go, color shampoo deepens in tone with continued use. While you can certainly use it just like a regular shampoo, if you want to make gray hair even less noticeable, we recommend leaving it on for about five minutes before rinsing.

Instead of choosing just one, can you use color shampoo and color treatment together?

Yes! In fact, we highly recommend combining them. By thoroughly coloring gray hair with the color treatment and swapping your daily shampoo for the color shampoo, it becomes much easier to maintain your color.

Replenishing color little by little with daily shampooing while using the color treatment whenever needed allows you to take advantage of both products' strengths for effortless gray hair care.

What sets this product apart as a shampoo?

It features double keratin*2 for damage repair and seaweed extract*3 to hydrate hair. As these ingredients penetrate inside the hair, they care for daily damage while delivering a shiny finish just like you've stepped out of a salon. We've also carefully considered the price to make it easy to use every day.

How Color Shampoo Dyes Hair Without Oxidation Hair Dyes

I've heard that using over-the-counter gray hair dye can affect future salon coloring.

That's a common concern. Oxidation hair dyes used in typical gray hair products develop color by penetrating deep inside the hair shaft. Because of this, once hair is dyed dark, it can be difficult to re-dye it a lighter shade later. On the other hand, Syoss Color Shampoo and Color Treatment primarily coat the hair's surface, so they have far less impact on salon treatments than standard gray hair dyes.

It seems like a convenient solution between salon visits.

Exactly. It's a handy item when you can't find time for a salon visit, or for touching up root gray hair that starts to show before your next appointment. With salon prices rising due to inflation, we hope people will reach for it whenever they want to care for their hair at home.

Blend gray hair gradually with daily shampooing, and thoroughly restore color with a color treatment whenever needed. Furthermore, by offering a formula that seamlessly fits between salon visits, "Syoss Color Shampoo" expands gray hair care options. Turning daily hair washing into gray hair care time serves as a powerful ally for busy modern people seeking efficiency.
