"Source of Black Hair Melanin": Adding the Lost Pigment "Melanin"

What Determines Hair Color: "Melanin Pigment"

As we get older, our hair turns gray. But have you ever wondered what gives hair its color in the first place?
In fact, it's "melanin pigment" that determines hair color.
The more melanin in the hair, the deeper the color.
But when factors such as aging prevent melanin from being produced, the melanin pigment in hair decreases, and the hair turns gray.

A "Source of Black Hair Melanin" Smaller Than Melanin Itself

So to color hair black, wouldn't it be enough to add the melanin pigment? That's what you'd naturally think. What made it possible to add the lost melanin in hair was something smaller than melanin itself—the "Source of Black Hair Melanin". Unlike melanin, whose large particles can't enter the hair as is, the "Source of Black Hair Melanin" is small enough to gather in the gaps between cuticle layers, where it firmly deposits in place.
And coloring with the "Source of Black Hair Melanin" brings many wonderful benefits.

An Ingredient Born of Melanin Research: Effective Gray Coverage, Natural Coloring.
Recolor with Ease!

The "Source of Black Hair Melanin" is small enough to gather between the cuticle layers and deposit in place.
Because it's an ingredient inspired by the melanin naturally found in hair, it can offer some uniquely appealing benefits.

Because It's Melanin, It Blends In: Natural Color and Shine, Just Like Your Own Hair

Its greatest feature is that, because it is an ingredient close to the melanin that determines hair color, the result is a natural finish—just like your natural hair before gray appears.
It's almost as if, rather than just covering gray hair, it gives hair a natural-looking dark color. Natural nuances emerge with how light catches the hair, and you'd never guess it had been colored.

Effective Gray Coverage in Five Minutes, with Minimal Damage

On the hair's surface, the "Source of Black Hair Melanin" deposits within the cuticle layers, and with each coloring, color builds up and gradually develops into a richer, deeper shade. Despite being gentle on hair, it deposits firmly to the cuticle, so compared to conventional dyes, the color resists fading during washing, and the beautiful finish lasts.
Plus, because it contains no diamine-based dyes, those who can't use regular hair color (diamine-based) can use it with peace of mind.

Greater Freedom in Recoloring, Too!

And there are delightful benefits even after you've colored your hair. A special feature of hair colored with the "Source of Black Hair Melanin" is the flexibility to enjoy your next color, too.
With conventional gray hair care, once you dyed your hair dark, it can be difficult to lighten it back up. By contrast, the "Source of Black Hair Melanin" can be broken down by regular hair coloring just like hair's own melanin, so when you want to recolor your hair a lighter shade, the new color goes on smoothly.
Because you can treat it just like natural hair, your coloring options expand dramatically.

Boost in Body and Resilience: A Sense of Volume, Too

What's more, the "Source of Black Hair Melanin" doesn't only give hair a naturally beautiful color—it slips inside the cuticle layers, working with every use to reinforce the hair itself. As it deposits in the cuticle layers, from the roots up, supple, springy body and shine return to your hair.
Hair is manageable from root to tip, and your fingers glide through it smoothly. On top of that, body and resilience grow stronger, soft natural volume rises from the roots, and the whole head of hair takes on a lighter, more airy movement.
So styling is easier than ever, with even more flexibility.
Beyond just coloring, hair itself regains its vitality with every use—that's another appeal of the "Source of Black Hair Melanin".

Everyday Moments Made Possible by the "Source of Black Hair Melanin"

The "Source of Black Hair Melanin" isn't just about coloring: it also gives us more flexibility in our hair care.
After the first few uses to reach your desired shade, it's just weekly maintenance from there. So those moments that used to be a worry—
"A sudden plan comes up, the gray at your roots is bothering you, but your salon appointment is two weeks out and you can't move it up… yet you don't want to mess up your color right before going."
Even in situations like these, you no longer have to put up with gray hair that bothers you.

And since natural hair color comes from adding an ingredient close to melanin, there's no effect on regular hair coloring, either. From now on, you don't have to give up brighter hair colors just because you color your gray.
What's more, with little damage to hair, body and resilience grow with every use. It guides your hair toward healthy strands that softly rise from the roots—and it really feels like you've gotten back the hair you had before gray was ever a concern!

This groundbreaking gray hair care is exactly what creates light, carefree days freed from the hassle of gray hair coloring.
