What Is the Bleach to Developer Ratio?
Although you should always follow the directions on your specific products, most professionals recommend using bleach and developer in a 1:2 ratio. Adding one part bleach to two parts developer gives you a creamy but easy-to-apply consistency.
The thick, runny texture spreads on quickly and evenly, so your color won’t come out patchy. You should use the same 1:2 ratio, regardless of your developer volume.
What Happens if You Put Too Much Developer in Bleach?
Putting too much developer in your bleach mixture will leave the mixture runny, so applying it will be challenging. It will also make keeping the bleach off your face and skin more difficult, which can lead to burns and irritation. But that’s not all.
Bleach with too much developer may not adhere to your strands well enough to lighten them effectively.
Lastly, your color may turn out pale and dull rather than fresh and vibrant. If you do accidentally add too much developer to your bleach mixture, discard it and whip up a new batch.
How to Mix Bleach Powder and Developer
Now that you know the correct bleach-to-developer ratio, we’d like to walk you through the rest of the process. Proper mixing is crucial if you want to achieve good results, so here are step-by-step instructions for how to mix your bleach powder with a developer.
Get Your Supplies Ready
The first step to mixing bleach and developer is getting all your supplies ready. Bleach doesn’t last long once it’s mixed, so you want to ensure everything is ready to go.
Make sure you grab the following before you start.
- Bleaching powder
- Gloves
- Processing cap
- Applicator brush
- Nonmetal mixing bowl
- Hair clips
- Plastic spoon
- Developer
- Developers come in a range of strengths. Here’s how to decide which strength to use. Keep in mind that you should always use the lowest effective developer volume.
- 10 Volume Developer - 10 Vol is the weakest developer. It’s too weak to lighten your hair in one session and is typically used for same-level coloring or when coloring your hair darker.
- 20 Volume Developer - This strength lightens your hair by one to two levels without a significant damage risk. 20 Vol is also ideal for toning blonde hair or covering grays.
- 30 Volume Developer - 30 Vol developer can lighten your hair by two to three levels.
- 40 Volume and 50 Volume Developer - These developer strengths can lift your hair by three or more levels. However, 40 and 50 Vol developers are incredibly damaging and shouldn’t be used unless you have significant experience.
Prepare Your Area
Bleach can lighten your clothes and irritate your skin, so make sure you protect your area before you start. Put on gloves and wear clothes you don’t mind getting stained.
Drape an old towel around your neck and tuck it into your shirt. You might also want to lay down old towels or newspapers to protect your surfaces from bleach splatter.
Part Your Hair
Once your bleach mixture is ready, you’ll have a limited amount of time to use it before it expires. Make sure you'll have enough time to apply the bleach by preparing your hair ahead of time. Part your hair into four or more sections and secure each section with a hair tie or clip.
Mix Your Bleach and Developer
Pour your bleach powder into a nonmetal, preferably plastic, bowl. Then, add two parts developer and one part bleach. Mix well until you’re left with a uniform consistency and no lumps.
Once you’ve mixed your bleach and developer, you’ll have to use it within the next twenty minutes. Using spoiled bleach increases your chances of severe damage and can throw off your color results.
Apply Your Hair Bleach Mixture
Once you’ve finished mixing your bleach and developer, it is ready to apply. Take down one of the back sections and separate a thin sliver of hair. Apply the bleach to your strands with an applicator brush.
Your roots process more quickly than the ends and mid-lengths of your hair. Start by applying the bleach about an inch from your scalp and work downwards.
Then, once you’ve finished with the rest of your mid-lengths and ends, go back and touch up your roots. Make sure your hair is fully saturated with bleach and cover it with a processing cap.
Set a timer and wait for the specified time.
This will usually be between 10 to 30 minutes, depending on your hair color and desired shade. The longer bleach sits on your hair, the more likely it is to cause damage, so keep an eye on how your color is lifting while you wait.
Rinse and Tone
As soon as you’ve reached your desired shade or your time is up, rinse your hair thoroughly with lukewarm water. Check your hair color for signs of yellow streaks or brassiness. If you want to neutralize them, wash your hair with a blue or purple shampoo.
Doing so will help your blonde come out cool and ashy or create the perfect base for your hair color. Follow up with a hydrating deep conditioner to help repair your strands and restore moisture. Then, dry your hair and evaluate your new color.
