Should I apply Root Vanish (RV) Coloring Brush to wet or dry hair?

You can apply our Root Vanish products to both wet or dry hair. Simply follow the instructions or watch our How To Videos here for the Coloring Brush and here for the Color Treatment. You should apply to clean dry hair and blow dry after for best results.


How many clicks do I need to start the RV Coloring Brush? How much should I pump out?

For your first time using our Root Vanish Coloring Brush, we recommend 12-20 clicks until you see the product moisten the pen brush, and then begin to apply the product to your roots. For first time pumping the Root Vanish Brush, you may also use a tissue to spread the color across the brush. Only 2 clicks are necessary to cover the part line and face line. You may also re-apply the next day for deeper coverage as well if you’d like.


How many clicks are necessary to cover my emerging roots?

The light weight, gel-based formula and the perfectly designed applicator brush allows RV Coloring Brush to spread and blend easily, exactly where you want to target coverage. Two pumps should cover the part and hairline where you see the regrowth. You may also use more clicks if you wish to layer and add depth and contours to the overall look, thanks to the layerable formula.


How long will Root Vanish last?

Each RV Coloring Brush applicator contains enough product for 100 clicks, or 50 uses. Depending on the quantity and frequency of use, your Root Vanish should last anywhere from 2-6 months.


Can I use RV Coloring Brush on my beard and mustache?

Yes! Our Coloring Brush is a perfect touch-up for men, including beards, side burns and mustache as it does not stain your skin. As your facial hair is generally thicker and courser than hair on your scalp, our brush applicator is very helpful to ensure proper coverage. We do not recommend using the product on eyebrows or anywhere near your eyes.


Can I use RV Coloring Brush or Color Treatment on chemically relaxed or permed hair?

Yes. The color is like a manicure for your hair and can be applied if you have chemically relaxed or permed hair. There are no harsh chemicals, like ammonia or peroxide, to damage the hair.


Why is Root Vanish better than a spray or a powder cover up?

Our state of the art formulations and pump-brush were created to provide the most natural and nourishing results to camouflage your roots. We believe the ability for you to easily control coverage, the color range offered and our natural botanical ingredients clearly make Root Vanish by Kazumi the best solution on the market. Our product does not flake away, will not dry out your hair, is not sticky or tacky to touch, it will not rub off onto your hands or get under your nails, it does not stain and does not create “spots” of color like some sprays do. Spray type colorants are water + oil based with a blend of color particles, which means they transfer, rub-off, easily when any water touches them, including rain or sweat.

Our mission is to create the safest, most gentle, and most caring grey coverup product possible but with gorgeous, natural looking and youthfully vibrant finish. Overtime with use, Root Vanish will make hair follicles and scalp healthier and your hair looking more radiant, stronger, and youthful.




Do I need to wash out RV Coloring Brush before I go to my coloring appointment?

No you do not need to wash out the product before going to the colorist; you will want to let them know you are using our product. Some clients take the Root Vanish Coloring Brush when they receive a blow-out for their stylists to touch-up their roots as well.


Is the RV Color Treatment a permanent color?

No, it is not permanent color and does not damage the hair cuticle to inject the color. Root Vanish products are like a manicure coat for your hair, the 22 botanicals also moisturize and treat your hair as the color gently and effectively coats each shaft.


What washing technique do you recommend if I accidentally get the product on my clothes while applying?

While Root Vanish sets quickly without any need for further drying or waiting and does not transfer, dropping a pumped brush on your clothes is a different story! For accidents, simply wash with soap and warm water. The natural botanical essences and oils allow for easy and clothing-safe removal.


Can I sleep with the RV Coloring Brush? How long will it stay on?

Root Vanish is non-transferable and safe for sleep, it doesn’t smudge or flake away. That said, if you do wet your hair and still have Root Vanish on, wait until it dries before lying down. If left unwashed, Roots Vanish can last until hair is washed in warm water with shampoo. To note, because it does not contain chemical stabilizers, applied areas will get lighter with air and light exposure, so spot re-application may be necessary. Keep an eye on your individual color richness.


Can I use other hair styling products with RV Coloring Brush? Should I apply before or after?

The beauty and innovation of Root Vanish is also in its ability to not affect your regular hair routine. You can use any product before or after, including leave-in hair conditioners, hair nourishing oils, dry shampoos, gel, mousse, you name it! Please note that you can get the best coverage using the least amount of product when Root Vanish is applied to dry hair.




My hair is in between two of the Root Vanish shades. Should I get the darker one or the lighter one? Do you recommend mixing?

You can go either way because of Root Vanish’s unique layerable formula! If you want more comprehensive and larger area coverage, go with a darker shade as you will only need a minimal amount to achieve the results. If you want to be able to choose levels of depth and layering, use a lighter shade that you can layer deeper in some areas while not in others. You are of course welcome to mix 2 shades together if it seems the best solution for you. The formula and shades blends seamlessly with each other to create a natural looking result.


Can I take the RV Coloring Brush on board when I travel?  Will it spill?

Yes! Many clients have told us its perfect for someone on-the-go or between color appointments, especially if you’re traveling—our Coloring Brush meets TSA regulations. It’s also the perfect touch-up for special events when traveling, or just looking and feeling your best. Great for men too, and works for facial hair touch-ups without staining the skin.




Was Root Vanish tested on Animals?

No, Kiwabi Root Vanish products are not tested on animals, and the products do not use any animal-based ingredients.


Is Root Vanish Ammonia Free?

All Kiwabi Root Vanish products are Ammonia and Peroxide Free.


Does Root Vanish contain any PPD or PTD: “phenylenediamines” or “phenylenediamines (toluenediamines)”?

None of our ingredients are PPD or PTD because our whole line philosophy is grounded in not damaging the integrity of each hair and to treat the hair instead of further damaging it. PPD and PTDingredients are typically only present in permanent (oxidative) hair colorants, that are harmful to the integrity and health of each hair strand. These oxidative colorants work inside the hair when mixed with peroxide, rather than on the outside of the hair like Root Vanish which does not pry open or damage the cuticles but rather coats it like a treatment manicure coat -- and therefore, is not permanent but can cover greys flawlessly.



I want to stock pile my favorite shade! How long will Roots Vanish last if unopened?

If you do not open the cap, standard time of use is within three years after purchase as long as you store it in a cool place out of direct sunlight.


Is KIWABI going to introduce other colors such as super light blonde and reds in the future?

Currently our Blonde works if your hair is a medium to darker blonde. Do not use if your hair color is a platinum blonde. Also note that this product does not have any bleaching agents so it will NOT lighten darker hair colors. Our Copper provides coverage for a range of redheads.


We are always looking to innovate with our range of products, and yes—if there is demand, there is possibility. Drop us a line and tell us more about what you’d like to see from us.


If the shade I got is too light or too dark, can I send it back?

Yes, as long as you purchased the product through Kiwabi's e-shop and this is your first time purchase with us, then you may exchange it for another shade within 14 days after receipt of the product. Please email us at with the color that you purchased and the color that you would like to replace with along with the automatic confirmation you received upon order.  You will only be charged for the shipping of the new product.
