Keep gray-looking hair looking naturally darker
Turn a routine wash into a simple color-maintenance ritual for gray or fading hair. This compact solid bar cleanses while helping hair look softer, shinier, and more nourished.
One Wash, Three Care Benefits

Support a darker look
The bar supports gray or fading hair that looks darker and more natural-looking. It is a color-maintenance step, not a guaranteed replacement for permanent dye.

Cleanse with botanical care
Korea Polygonum branding gives this wash a botanical focus. Its nourishing and repairing claims suit hair that feels dry, damaged, dull, or affected by signs of aging.

Skip the bulky bottle
The dense black shampoo bar is a compact alternative to liquid shampoo. It takes up little room in the shower and keeps the wash routine simple.
Use It Like Your Normal Shampoo
- 1Wet hair and the bar
Soak your hair, then wet the solid bar until it is ready to lather.
- 2Build a gentle lather
Rub the bar between wet hands or glide it lightly through the hair. Work the lather over the scalp and lengths.
- 3Massage and rinse
Massage lightly, then rinse well until the hair and scalp feel clean. Follow with your usual conditioner if needed.
- 4Store it dry
Rinse the bar clean and place it on a draining dish away from standing water.

A Softer Way to Maintain Color
- 1The Mirror Check
Gray roots, faded lengths, dryness, or flakes can suddenly dominate your reflection. Hair may feel harder to manage even when the rest of your routine has not changed.
- 2A Different Wash
Permanent dye takes time, root sprays look temporary, and ordinary shampoo leaves the color-maintenance problem untouched. Korea Polygonum Darkening Shampoo brings a more focused purpose to a familiar shower step.
- 3Set Realistic Expectations
The dense solid bar cleanses at the scalp and supports a darker-looking appearance. It is a rinse-off cosmetic, not permanent dye, so coverage and visible color change vary by person.
- 4The Easier Routine
With regular washing, hair feels freshly cleansed and softer, while its color looks more polished and naturally darker. It is a straightforward way to care for hair between color appointments.

Questions and answers
No. It is a rinse-off darkening shampoo bar that supports a darker-looking appearance. Results vary, and it is not a replacement for permanent dye or guaranteed gray coverage.
It is intended for regular cleansing and nourishing care, including hair that feels dry or affected by dye and heat styling. Patch test first, rinse thoroughly, and follow with conditioner if your lengths need extra care.
The bar is matte black, so rinse your hands, shower surfaces, and towels well after use. Store it dry and do not place it against light fabric while wet.
Use caution if your scalp is sensitive. Patch test first, massage lightly, avoid broken skin, and stop if redness, burning, or itching becomes worse. Persistent scalp symptoms need professional guidance.
Use it as part of your normal washing routine and adjust to how your hair and scalp feel. Start gently rather than rubbing the bar aggressively or leaving it on the scalp.
You receive one black Korea Polygonum solid shampoo bar and one product box. The bar weighs 40g.
