Splat Hair Dye Review: Why It Won't Fully Wash Out

Splat hair dye is a cheap, very heavily pigmented semi-permanent color, around $12.99 for a complete kit, and on light or bleached hair it delivers some of the brightest blues, pinks and purples you can buy at a drugstore. It is good at that one job. The catch is the part the box calls semi-permanent: Splat stains almost everything it touches, and on bleached hair it rarely washes all the way out.
So the real decision is not "is Splat good". It is "am I happy to live with this color, or a faded ghost of it, for the next few months". Answer that honestly, pick the Splat line that matches the hair you are starting with, and it is a fine product. Skip that question and it becomes the dye people on Reddit warn each other about.
Is Splat hair dye good?
Yes, for bold color on hair that is already light, and no, if you want something you can wash out cleanly in a few weeks. Splat's own formulas are vegan, cruelty-free and free of PPDs, parabens and sulfates, and the dye itself is a conditioning deposit-only color that does not lift your hair.
The damage people blame on Splat usually comes from the bleach packet inside the Original Complete Kit, not from the color. The complaints that are actually about the dye are staining and staying power, and both come from the same thing: there is a lot of pigment in that bottle.
On pre-lightened hair, a fresh Splat pink looks like the picture: saturated, even, and very loud. That result is exactly what the kit promises, and it is why the brand has fans. It is also the version that is hardest to get rid of later, because bleached hair is porous and holds pigment for longer than you want it to.
Which Splat kit is which
Splat sells several lines that look alike on the shelf and do very different jobs. Buying the wrong one for your hair is the most common way to end up disappointed. Prices below are as listed on the Splat store in September 2026.
| Splat line | What is in it | Best for | Price |
|---|---|---|---|
| Original Complete Kit | Bleach packet plus semi-permanent color | Brown hair you are willing to lighten first | $12.99 |
| Midnight | Semi-permanent color, no bleach | Medium brown to pale blonde hair | $12.99 |
| Double Lift | Permanent color that lifts up to four levels | Virgin medium to dark brown hair | $11.99 to $12.99 |
| 10 Wash | Softer semi-permanent, "soft and easy fade out" | Testing a shade you are not sure about | $9.49 |
| 1 Wash | Temporary color | One night, one event | $8.99 |
| Singles | A bottle of color only | Touch-ups and color mixing | $5.00 |
| Color Masques | Color-depositing conditioner | Keeping an existing shade bright | $7.99 |
If you remember one row, make it the 10 Wash. It is the only Splat line designed to leave, and it is the right first purchase for anyone who is not sure.
Splat hair dye by your starting hair color
Your natural color decides what Splat can do far more than the shade on the box. The dye adds color on top of what is there. It cannot make dark hair lighter, except in the permanent Double Lift line.
| Your hair now | What Splat gives you | Which line |
|---|---|---|
| Black or very dark brown | A tint that shows mostly in sunlight | Double Lift, or Midnight for a subtle sheen |
| Medium brown | A rich jewel tone, darker than the box | Midnight, or Original Kit for brighter |
| Light brown or dark blonde | A clear, strong color | Midnight or Original Kit |
| Blonde or already bleached | The brightest result, closest to the box | Original color, Singles, 10 Wash |
| Box-dyed dark color | Very little shows | Remove the old color first |
Black and dark brown hair
On dark hair without bleach, even the Midnight shades land as a tint rather than a color. Indoors you read as brunette. Outside, the light catches a violet or blue sheen through the top layers, which is exactly what the woman below has.
If that is the look you want, it is a good one and it is low risk, because unbleached hair lets go of the pigment more readily. If you want the color you saw on the box, you need lift, which means either the bleach in the Original Kit or the permanent Double Lift line. Splat describes Double Lift as best for virgin medium to dark brown hair. How far your hair can go before it gives out depends on where it starts, which is laid out level by level in our guide to bleached hair.
Medium and light brown hair
This is where Splat's Midnight line was designed to sit. Splat lists it for medium brown to pale blonde hair and says it lasts four to six weeks depending on your hair type and porosity. Expect the result to come out a step deeper than the swatch, and warmer if your brown has red in it. Reds are the most forgiving shade here, because warm undertones in brown hair work with them instead of against them.
If you already know red suits you, this is the safest Splat you can buy. The same logic behind choosing the right blonde for brown hair applies here: work with the warmth you have rather than fighting it.
Blonde and pre-lightened hair
Pale hair is where Splat looks most like the box and where it is most permanent in practice. Bleached hair has a raised, porous cuticle, and Splat's pigment settles in deep. A common story on hair dye forums is someone bleaching over Splat to remove it and finding the color stays put.
If you are blonde and you want a trial run, use the 10 Wash or just color the underneath layer. A hidden section is how peekaboo hair started, and it is the cheapest insurance you can buy.
Why do people say not to use Splat hair dye?
People warn against Splat for three reasons: it stains skin, towels and bathrooms badly, it rarely washes fully out of bleached hair, and the bleach in the complete kit is harsh on hair that is already processed. None of that makes it unsafe to use. It makes it a commitment.
It stains everything. Splat's instructions tell you to put petroleum jelly around your hairline, ears and neck, and to rinse with cold water "to lock in color and prevent staining". Take that seriously. Grout, white towels, pillowcases and the shower curtain all pick it up.
It does not fully leave. On porous hair the color fades in brightness, but a tint hangs on. The common complaint from colorists is not that Splat damaged someone's hair, it is that they could not get the Splat out before putting a new color on.
The bleach is the rough part. The kit's bleach is a pre-measured packet that "lifts in just 30 minutes". On virgin hair that is fine. Over hair that is already bleached or box-dyed, you are stacking damage on damage, and nothing in the kit adjusts for that.
How long does Splat hair dye last?
Splat says its Midnight shades last four to six weeks depending on hair type and porosity. In practice that is how long the color stays bright. On bleached hair a paler version of it can stay for months, until the dyed length is cut off.
That is roughly where a hot pink on pre-lightened hair ends up after a few weeks of washing: a soft pastel pink, and by then your natural roots are coming through at the part too. Some people like this stage more than the fresh color. Plan for it either way, because this is the version you will wear longest.
What speeds fading: hot water, sulfate shampoos, sun, chlorine and heat styling. What slows it: washing less, cold rinses, and a color-depositing conditioner in the same shade once a week.
How to use Splat hair dye
Splat's instructions for the Original Complete Kit are clear, and most bad results come from skipping steps rather than from the product. This is the order the kit asks for, with the timings Splat prints.
How to use Splat hair dye
- Do a strand test and a patch test
Dye a small hidden section first to see the real color on your hair, and test the product on your skin before applying it to your whole head, as the FDA recommends for any hair dye.
- Protect your skin and bathroom
Put on the gloves from the kit, apply petroleum jelly along your hairline, ears and neck, and wear an old towel or shirt you do not mind ruining.
- Bleach, if you are using the kit's bleach
Mix and apply the bleach, checking every 10 minutes by wiping a strand. Process for up to 30 minutes in total, then rinse thoroughly with lukewarm water and shampoo out all the bleach.
- Dry your hair
Apply the color to dry hair after the bleach is fully washed out.
- Apply the color generously
Saturate every section completely. Patchy results nearly always mean too little product, which is why Splat recommends two kits for long or thick hair.
- Process for 45 to 60 minutes
Add 15 minutes if your hair is thick.
- Rinse with cold water
Rinse until the water runs clear or only slightly tinted, then shampoo with a sulfate-free shampoo and use the deep conditioner from the kit.
Mistakes that cost you months
- Putting Splat over box dye. Dark box color blocks the new shade, so you pay twice and see almost nothing.
- Using the kit bleach on already bleached hair. It is the fastest route to breakage and the kit gives you no way to tone it down.
- Rinsing with warm water. Warm water opens the cuticle and lets pigment run, onto your face and down the drain.
- Choosing a color you have never seen on yourself. Because Splat lingers, a shade that washes out your skin tone is a shade you live with for a long time.
- Going straight to bleach to remove it. Bleach on top of Splat can push blue and green into a murky cast. A colorist will usually want a color remover first.
If you do end up in a salon to take it out, say this before anything else:
Say this to your barber
I have Splat semi-permanent dye in my hair and I want to try a color remover before any bleach goes on.
Can you use Splat without bleach?
Yes. The Midnight line is made for it, and the color in the Original Kit can be used on its own. Splat's own tutorial shows Purple Desire turning unbleached hair a deep plum. On dark hair you get a tint, on light brown and lighter you get real color, and on unbleached hair it also washes out more readily than it does on bleached hair.
This is the lowest-risk way to use Splat, and on medium brown hair the Midnight shades are the sweet spot.

The free way to test Splat is a strand test, and you should always do one. It tells you how the color takes on your hair. What it cannot tell you is whether the color works next to your face, your skin tone and your eyebrows, and with a dye that hangs around for months, that is the question that matters.
That is the gap a virtual try-on closes, and most of the best AI hairstyle apps include a color changer. Upload one selfie to our hair color try-on and you can see teal, magenta or cherry red on your own head before you open a bottle. Your first look is free.
Yours could be here.
Start with one selfie.
One photo, twenty seconds, and you'll know. Free account, no card for your first render.
If you are torn between a vivid shade and something softer, put them side by side on the same photo. Plenty of people discover that a warm red or a copper-based color like calico suits them better than the blue they came in for.
Splat is a good, cheap, very bright dye with one honest warning: treat semi-permanent as a best case. Match the line to your starting color, use the 10 Wash if you are unsure, protect everything in your bathroom, and rinse cold.
Most of all, pick a color you would still be happy wearing in a faded version two months from now. If you want a lower-commitment way to play with color first, hair tinsel comes out in minutes, and if you are heading the other way, our guide to going grey covers growing color out gracefully.
Frequently asked questions
Mostly because it stains and it is hard to get out. Splat is heavily pigmented, so it marks skin, towels and grout, and on bleached hair a tint often lasts long after the bright color has faded. The bleach in the complete kit is also harsh on hair that is already processed.
The color itself is a deposit-only semi-permanent dye, free of PPDs, parabens and sulfates, with conditioning oils, so it is not what damages hair. The bleach in the Original Complete Kit is where damage comes from, especially on hair that has been bleached or dyed before.
Splat says its Midnight colors last four to six weeks depending on hair type and porosity. On bleached hair the color fades in brightness over that time but a lighter tint can stay for months.
Splat's instructions for the complete kit say to process the color for 45 to 60 minutes, and to add 15 minutes for thick hair. The kit bleach is processed for up to 30 minutes in total, checked every 10 minutes.
Rinse with cold water until it runs clear or only slightly tinted, then use a sulfate-free shampoo and the deep conditioner from the kit, as Splat's instructions say. After that, wash as little as you can and always with cool water.
Because there is a lot of loose pigment that did not bind to the hair. Cold rinses, sulfate-free shampoo and dark pillowcases for the first week all help, and the bleeding slows after the first few washes.
Yes. The Midnight line is made to be used without bleach on medium brown to pale blonde hair, and the color from the Original Kit can be used on its own. On dark hair expect a tint that shows in sunlight rather than the color on the box.
Usually shorter than on bleached hair, because unbleached hair is less porous and lets go of the pigment more easily. That is why using it without bleach is the lower-risk option if you are unsure about the color.
