Milbon Oldive Dye nb
MILBON's Oldive Botte is a salon-grade permanent hair dye from Japan, sold in a squeeze bottle designed for root touch-ups and full-head color at home. This collection covers the NB (Natural Beige) tone family, which runs from deep b2 for the darkest, coolest coverage up through lighter shades like b8 and b9 for a softer beige finish. NB sits between ash and warm brown, so it neutralizes red and orange undertones in Asian hair while keeping the result natural rather than flat or gray-toned. Several listings include the oxidizer separately, which is standard for oxidative color: you mix dye and developer just before application rather than buying a pre-mixed product. Pick your shade by how much gray you're covering and how light you want to go, not just by the number on the label.

How to choose and use MILBON Oldive NB hair dye
MILBON Oldive Botte is a Japanese permanent hair color built for salon-quality results at home. The NB tone family (Natural Beige) is one of the most forgiving lines for covering gray without the color turning brassy or overly ashy. This guide walks through what the shade numbers mean, how to pick a level, how the oxidizer works, and how to apply it safely.
What the NB tone family is for
NB blends beige and natural pigments to cancel out red and orange undertones common in dark Asian hair, without pushing the result cool and ashy. It reads as a soft, warm-neutral brown that looks close to natural hair, which is why it is a common choice for gray coverage rather than for a dramatic color change.
Reading the level number (b2 to b9)
The number before NB is the depth level. Lower numbers sit closer to black-brown and deliver denser, more opaque coverage; higher numbers lift the hair lighter and let more of the beige tone show through. As a rough guide:
- b2-b3: darkest, densest coverage, closest to natural black hair.
- b4-b6: mid-brown range, the most common pick for full gray coverage with a natural finish.
- b7-b9: lighter beige-brown, for hair that is already color-treated or lightened, or for a softer overall look.
If you are unsure, choose the level closest to your natural pre-gray color rather than the color you want to end up with.
Oxidizer: why it's sold separately
Oldive is an oxidative permanent color, so it needs a developer (oxidizer) to open the hair cuticle and let the pigment deposit. Some listings bundle a matching oxidizer, others list the dye and oxidizer as separate purchases so you can reuse one bottle of oxidizer across several color applications. Always mix dye and oxidizer only right before you apply, in the ratio printed on the package, and use the mixture within the working time stated on the label.
Using the Botte bottle applicator
"Botte" refers to the squeeze-bottle format, which is designed for direct root application. After mixing dye and oxidizer inside the bottle, shake to combine, then apply the tip directly along the parting to target regrowth first. This format is easier to control than a bowl-and-brush setup for touch-ups, but for a full head of virgin color, a bowl and brush still gives you more even coverage.
Patch test and processing time
Run a patch test on skin at least 48 hours before your first use of any new box, even if you have used the brand before, since sensitivity can develop over time. Once applied, leave the color on for the processing time printed on the package, usually in the 20-30 minute range for gray coverage, then rinse until the water runs clear and follow with a color-safe conditioner.
Aftercare to hold the tone
Beige tones fade toward warm or brassy faster than ash tones, especially with hot water and sun exposure. Wash with lukewarm water, space out shampoo days where you can, and use a sulfate-free or color-care shampoo to slow fade. A once-a-week toning or color-depositing conditioner in a cool or beige tone helps keep NB looking fresh between full applications.
Who this line suits
Oldive NB works best for anyone doing regular root touch-ups on dark hair who wants a natural, non-ashy result without visiting a salon every few weeks. If your hair is already heavily lightened or bleached, check the level guidance on the box first, since NB is formulated with natural-to-dark hair in mind.
FAQ
Frequently asked questions
FAQ
Frequently asked questions
What does the NB in MILBON Oldive NB mean?
NB stands for Natural Beige, a tone family that cancels red and orange undertones in dark hair while staying warm-neutral instead of ashy. It's a common choice for gray coverage that still looks like your natural color.
How do I choose between b2, b5 and b8?
The number is the depth level: lower (b2-b3) is darkest and gives the densest coverage, mid-range (b4-b6) is the most common pick for full gray coverage, and higher (b7-b9) lifts lighter for hair that's already color-treated. Match it to your natural pre-gray color if you're unsure.
Do I need to buy the oxidizer separately?
Some listings bundle a matching oxidizer, others sell dye and oxidizer separately so you can reuse one oxidizer bottle across several applications. Check the specific listing before you order, and mix them only right before applying.
What is the "Botte" bottle format for?
Botte is the squeeze-bottle applicator built for direct root touch-ups. You mix the dye and oxidizer inside the bottle, shake, then apply the tip along your part to target regrowth without needing a bowl and brush.
What's the processing time for Oldive NB?
For gray coverage, Oldive NB typically develops in the 20-30 minute range, but always follow the exact time printed on your specific box. Rinse until the water runs clear, then use a color-safe conditioner.
Do I need a patch test before using it?
Yes. Run a patch test on skin at least 48 hours before your first use of any new box, even if you've used the brand before, since sensitivity can develop over time.
Will NB look natural on already-colored hair?
NB is formulated with natural-to-dark hair in mind. If your hair is already heavily lightened or bleached, check the level guidance on the box first, since the result can lift differently on pre-colored hair.
How do I stop the beige tone from turning brassy?
Beige tones fade toward warm faster than ash tones. Wash with lukewarm water, space out shampoo days, use a sulfate-free or color-care shampoo, and add a weekly cool or beige toning conditioner to keep the color fresh between full applications.
