Bleach activators are compounds that enable a lower wash temperature than would otherwise be required to achieve full bleach activity in the wash liquor. Bleaching agents, mostly peroxides, are usually only sufficiently active above 60 °C.
Effortlessly create a natural shine with Nature’s Essence Lacto Bleach. This natural milk bleach works without an activator and gently removes impurities and dead cells from the skin’s surface.
The bleach activator supports the action of the bleach, typically perborate or percarbonate, which upon dissolution releases hydrogen peroxide by reducing the temperature required to carry out the bleaching reaction.
Developer, also known as activator or peroxide for short, is mixed with bleach or dye to lighten or color hair. It is a creamy product that contains hydrogen peroxide and the amount of hydrogen peroxide determines the developer volume.
Use 40 Volume Developer
It contains 12% peroxide which can burn sensitive scalps. When bleaching your hair at home, it’s much better and safer to do multiple bleaching rounds with 30 or even 20 volume developer and use lots of conditioning treatments and protein builders in between.
Create a subtle lightening effect
Your colorist can use this technique if you want to subtly lighten your hair. The water dilutes the bleach, resulting in a slight color change. The water will also distribute the bleach evenly. This avoids harsh transitions between colors and creates a smoother lightening effect.
Open the tube of bleaching cream and squeeze it onto the activator powder. Use a plastic spatula to even out the cream and keep pressing until your mixture reaches the correct mark (that’s around 15ml for most kits). While most bleaching cream kits require a 2:1 ratio, some may require a 1:1 ratio.
Without bleach, just a 20 volume developer can lighten your hair by about one level. So if you currently have a level 5 light brown, using developer alone with 20 volume can lift it to a level 6 dark blonde.
No, developer is not the same as bleach. When you buy a whitening kit, you will notice a few different items in the box. Two of the most important are bleach powder and developer. These two must be used together to lighten your hair, but developer and bleach are not the same thing.
Mix in your 3% hydrogen peroxide and stir into the mixture. This will give the slime a soupy, liquid state, but be careful as you don’t want it to become too runny. Finally, pour in your second slime activator, your saline solution.
If you skip the developer and use a conditioner instead, your color may not hold or may come out incredibly patchy and uneven. This is because conditioner and developer have two very different effects on hair.
While you can use hydrogen peroxide as a developer, using it without additives will not give the desired results. Even if you apply moderate-strength hydrogen peroxide, it will only cause a slight flash with no noticeable results.
The recommended ratio of bleach to developer is 1 part bleach to 2 parts developer. This gives you a fairly liquid mixture that is easy and quick to apply. Our recommended “fairly runny” blend makes it easy to evenly coat all hair, avoiding blotchy results.
The best developer for darker hair is Volume 20. Volume 30 and 40 lifts your hair color significantly so the color isn’t as dark. If you already have dark hair, you can also use Volume 20 Developer to minimize damage.
Step 2: Add at least part shampoo. With this in mind, the ratio becomes 1:2:1 bleach powder to developer to shampoo. The amount of bleach powder you add should match the same amount of shampoo.
