Ever looked in the mirror after three hours of smelling like sulfur and ammonia only to find your hair is the color of a neon Cheeto? It happens. More often than you’d think, honestly. You were aiming for that icy, Pinterest-perfect Nordic blonde, but instead, you’ve got something that looks like it belongs on a construction cone. This usually happens because there is a massive disconnect between what people think bleach does and what the bleached hair levels chart actually tells us about biology.
Hair doesn't just "turn" blonde. It’s a literal demolition project. You are stripping away layers of pigment, one by one, until there is nothing left but the structural skeleton of the hair shaft. If you stop too early, you get orange. If you go too far, your hair ends up in the shower drain. Understanding the scale from 1 to 10 isn't just for professionals; it's how you save yourself from a $400 corrective color appointment at the salon.
The Science of the Bleached Hair Levels Chart
Think of your hair like a dark mahogany wood table. If you want to paint it white, you can’t just slap a translucent white stain on it and expect it to look like clouds. You have to sand it down. In the world of hair, we use the International Level System. It’s a scale that runs from 1 (jet black) to 10 (lightest blonde). Some brands, like Redken or Wella, might occasionally reference an 11 or 12 for "high lift" tones, but for the sake of reality, 1 to 10 is your universe.
When you apply lightener, the chemicals enter the cortex and oxidize the melanin. Here’s the kicker: your hair doesn't just get "lighter versions" of your natural color. It reveals "underlying pigments." This is the part that ruins everyone’s day. If you’re a Level 2 (dark brown), your underlying pigment is red. When you hit Level 5, it’s a stubborn, rusty orange. By Level 8, you’re looking at yellow-gold. You cannot skip these steps. It’s a biological roadmap.
Breaking Down the Levels (The Ugly Truth)
Levels 1 through 4: The Dark Zone.
At this stage, you’re dealing with massive amounts of red and brown pigment. If you bleach Level 1 hair, it’s going to turn a deep, muddy red-brown first. Most people get scared here and wash it off. Don't. You're just in the middle of the process.
Levels 5 through 7: The Orange Purgatory.
This is where DIY projects go to die. Level 5 is a loud orange. Level 6 is more of a burnt sienna. Level 7 is what we call "orange-yellow." If you want to be a cool-toned brunette or a dark "mushroom" blonde, you actually have to get past this stage or use a blue-based toner to cancel out the heat. If you try to put a "pale ash blonde" box dye over Level 6 orange hair, literally nothing will happen. You'll just have shiny orange hair.

Levels 8 through 10: The Blonde Goalpost.
Level 8 is the color of a banana peel on the outside. Level 9 is the inside of the banana peel. Level 10 is almost white, like a pale primrose. If you want silver, platinum, or pastel pink, you must reach Level 10. There is no shortcut. Putting lavender dye on Level 8 hair will just turn it a muddy grey-brown because the yellow in the hair cancels out the purple.
Why Your Hair Type Changes the Math
Not all hair reacts to the bleached hair levels chart the same way. Texture is the silent killer. Fine hair lifts like a dream because the chemicals don't have much "ground" to cover. You can sometimes jump four levels in one sitting. But if you have coarse, "resistant" hair, the cuticle scales are packed so tightly that the bleach struggles to even get inside.
Porosity matters too. If you’ve spent the last three years dyeing your hair "Natural Black" from a box at the drugstore, your hair is essentially "stained." Those metallic salts and heavy pigments don't just lift; they cling. This is why a professional will often tell you that reaching a Level 10 from previous black dye might take three sessions over six months. They aren't trying to overcharge you. They are trying to keep the hair attached to your scalp.
The Role of Developer
You can't talk about levels without talking about volume.
- 10 Volume: Depositing color or very slight lifting.
- 20 Volume: The standard. Lifts 1-2 levels.
- 30 Volume: Lifts 2-3 levels. Dangerous if left too long.
- 40 Volume: Basically liquid fire. It lifts fast, but it compromises the hair's integrity almost instantly.
Most pros stay away from 40 volume on the scalp. It’s just too risky. It’s better to do two rounds of 20 volume than one round of 40. Slow and steady wins the "not-being-bald" race.

Tone is Not the Same as Level
This is the biggest misconception I see. Someone will look at a bleached hair levels chart and say, "I'm a Level 9," and then wonder why their hair looks like a highlighter. Level is how light it is. Tone is the flavor of that light.
Once you reach your desired level, you have to "neutralize" the raw pigment. This is where color theory (the color wheel) comes in.
- To kill Level 8 Yellow: Use Violet.
- To kill Level 7 Orange-Yellow: Use Blue-Violet.
- To kill Level 6 Orange: Use Blue.
If you are a Level 7 and you use a violet toner, you’ll still have orange hair. Why? Because violet only neutralizes yellow. It doesn't have enough "muscle" to cancel out the orange. You have to match the toner's intensity to the level of the hair. This is why "purple shampoo" doesn't fix orange hair. It’s not formulated for that level of the chart.
Real World Dangers: When the Chart Lies
Sometimes the hair looks like a Level 10 but feels like wet spaghetti. This is "over-processing." When you strip the pigment, you also strip the disulfide bonds that give hair its strength. If your hair is stretchy when wet or feels "mushy," you've hit the end of the road. No more bleach. At this point, you aren't moving up the chart anymore; you're just disintegrating the protein.
Experts like Guy Tang or Brad Mondo often highlight that "lift" isn't infinite. Every head of hair has a ceiling. For some people with very dark, thick hair, a Level 9 might be the absolute limit before the hair gives up.

Practical Steps for Your Next Move
If you're planning on using the bleached hair levels chart to guide your next DIY or salon visit, stop and do these three things first. They will save you a lot of grief.
Perform a Strand Test. I know, it's boring. Do it anyway. Snip a tiny bit of hair from the nape of your neck and apply your lightener. See how long it takes to reach the next level. If it turns bright orange and stops lifting after 40 minutes, you know you can't reach platinum in one day.
Identify Your Starting Point Honestly. Look at your roots in natural sunlight. Don't guess. If you think you're a Level 5 but you're actually a Level 3, your timing will be off, and you'll end up with a mess. Most people underestimate how dark their hair actually is.
Buy a pH-Bond Builder. Products like Olaplex, K18, or Wellaplex aren't just marketing hype. They actually help reconnect those broken bonds during the bleaching process. If you’re trying to move more than 3 levels up the chart, these are non-negotiable.
Stock Up on Protein and Moisture.
Bleached hair is "hungry" hair. It has holes in the cuticle. You need a balance of protein (to fill the holes) and moisture (to keep it from snapping). Use a deep conditioner once a week, but don't overdo the protein, or the hair will become brittle and "glassy."
Understand that "Level 10" is a destination, not a starting point. It takes patience, a lot of purple-tinted goo, and a realistic expectation of what your biology allows. If you treat the chart like a map rather than a suggestion, you'll actually end up with the color you want.
