What Is Developer & What Exactly Does it Do?
Developer or Activator is a essentially hydrogen peroxide in a cream base.
It is an essential element in any coloration involving permanent hair color and bleaching process.
The hydrogen peroxide opens the hair cuticle.
It also combines with the permanent hair color, toner or bleach and helps activate it.
Thanks to the developer and color combination, the following things happen:
- The hair cuticle gets opened so that the color pigments can penetrate it.
- The natural color molecules (the hair melanin, in other words) and also molecules from previous color applications get lifted out
- New color pigments get delivered and get inserted into the cortex of the hair.
- Once installed, the color molecules swell, develop and expand and ultimately become a permanent part of the hair shaft.
- Once installed correctly thanks to developer, the color is essentially permanent.
- You will only need to worry about regrowth
In addition to the above, the developer + color combination also does the following:
- Softens coarse hair and adds body to fine hair.
- Alters the internal body of the hair fiber permanently.
Which is why hair oftentimes feels softer stronger and thicker after a coloring.
Provided, of course, that it has been done right.
How Should I Choose the Right Strength of Developer?
First off, what exactly are you trying to do?
Are you trying to lift the hair level, go darker, or stay level-on-level?
Are you trying to use color, high lift color toner or bleach?
Because the answer is going to depend on these questions.
We will go through all these cases one by one in this blog now.
Developer Choice Going Lighter With Regular Color
Here are the rules for developer choice when going lighter using regular professional color:
- Use 20 Vol if you are aiming for a 1-2 level lift.
- Use 30 Vol is you are aiming for a 2-3 level lift.
- Use 40 Vol if you are aiming for a 3 level lift and if the hair is particularly difficult to color.
- Note that the mix should always be respected.
- 1+1 is the right mix for Ugly Duckling colors and you should stick to that.
- And not try to tweak the mix in order to get more lift!
What if you are aiming to lift by more than 3 levels?
In that case you can't do it using regular permanent color.
You will need to use a high-lift color or alternatively use bleach first, then color.

Developer Choice Going lighter Using High-lift color
High lift colors have extra lift built in them and can lift up to 4-5 levels.
This is convenient if you are looking to avoid using bleach.
The rules for using high lift color are as follows:
- Use 30 Vol developer.
- Make your mix 1 part color to 2 parts developer.

Developer Choice Going Lighter With Bleach
Using bleach is not difficult.
But you do need to follow the rules very carefully.
For bleach, follow the rules below:
- For up to 3 levels lift, use bleach with 20 Vol developer.
- For greater than 3 levels lift, use bleach with 30 Vol developer.
- For second time bleach applications, use only 20 Vol developer. Otherwise you will damage the hair excessively.
- For the root area, use 20 Vol unless the hair is really really dark.
- Once the hair has been lightened correctly, you should only need to use 20 Vol developer with your color.
- Basically, 30 Vol should only be used once, and preferably on the lengths and not on the root area.
- Be aware that not all bleaches are the same in terms of lifting properties.
- Ugly Duckling bleaches will work very well with 20 and 30 Vol developer and will never need anything stronger.
- Once again, you need to respect the mix.
- 1 part bleach to 2 parts developer is what we recommend.

Developer Choice For Grey Hair Coverage
- For any grey hair application, use 20 Volume developer (6% peroxide).
- Grey hair needs extra softening to open up.
- Also, in the case of salt and pepper hair when going blonde, the "pepper" part needs to be lifted up. Otherwise it will always stick out.
- Hence, 20 Volume developer is what you should use for grey hair coverage, not 10 Volume (as is sometimes taught in cosmetology classes).
- The mix is, as always, 1+1.
- And try to develop the color for at least 20-30 minutes.
- You will get better grey hair coverage that way.
Developer Choice for Level-on-Level Coloring or Coloring Darker
- When coloring level-on-level or darker, you can use 10 or 20 Vol developer.
- Once again, the mix should always be respected: 1 part color to 1 part developer.
Developer Choice When Toning Blonde Hair
- For toning with Ugly Duckling cream based toners, we recommend that you use either 10 or 20 Volume developer.
- For toning with Blondify Liquid Toners, the mix is also 10 or 20 Vol.
- Be aware that cream toners have a mix of 1 part toner to 1 part developer.
- Whereas liquid toners are best used 1 part toner to 1 part developer.

Developer Choice When the Hair has been Previously Colored.
- Hair that has had color deposited into it will be harder to lift than virgin hair.
- In particular, hair that has been colored black or dark with box dye is notoriously difficult to remove.
- Henna hair, metallic dyed hair are also difficult to remove.
- So are (paradoxically) some semi-permanent colors.
- Which are oftentimes not semi-permanent at all.
- These colors work by staining the surface of the hair and can be very stubborn.
- In such cases you would need to bump up the developer choice by one level.
How about Porous hair? Which strength of developer should I use?
- Porous hair is easily lifted and it absorbs the color very well. But the color will fade quickly.
- Very often it is the ends which are porous, whereas the roots and mid-lengths are in much better condition.
- Very often these porous ends are blonde anyway.
- So if you are trying to go lighter and the ends are blonde and porous you should use a lower volume developer or shorten the processing time at the ends by only applying in the last 5-10 minutes or so.
- When darkening porous ends, you would need to use the regular volume of developer to ensure better penetration of color pigments.
I need to lift a lot & I don't want to use bleach. Is it OK to use 40 Vol developer with my color instead?
- It is not recommended to use 40 Vol with color.
- Unless your hair is particularly difficult to lift or has been previously colored darker.
- 40 Vol developer swells up the hair cuticle so much it risks blowing it apart permanently.
- You would be better off using a quality bleach which lifts well.
- Use the bleach with 20 Vol or 30 Vol. developer as indicated above.
- Then use your color with 20 Vol. developer.
- You will get much better results that way.
- Incidentally, this is perhaps the most common process as used by hairderssers in a salon.
- It's called "Double Process Blonding". And it's common for a reason!

I bleached my hair with 30 Vol and my hair is still orange. Should I use the bleach with 40 Vol developer?
- What bleach were you using?
- All bleaches are not the same and some beauty store bleaches in particular have very poor lifting properties.
- Using a poor quality bleach with 40 Vol developer is unfortunately just asking for trouble.
- Better to use a quality bleach which lifts fast and well - and use 20 or 30 Vol developer with that.
Which Brand of Developer Should I Use?
Of course, we do recommend that you use Ugly Duckling developers when possible.
They are made to the very highest cosmetics standards. They activate well, in a controlled way, and they will respect hair integrity.
That being said, it is not strictly necessary to match the brand of developer with the brand of color or bleach.
Provided you get the choice of developer strength, mix and choice of product right.
However, we do recommend that you note the following:
- Make sure that the developer has a manufacturing date controlled by lot number to guarantee freshness.
- Be aware that stale developer loses its lifting power.
- If a bottle of developer has swelled slightly, throw it away and don't use it. It is stale.
- In general, we don't recommend you use gallon bottles of developer.
- You will get far better quality and freshness using liter (33 oz) bottles.
- Try to use a cream based developer. Not a liquid based peroxide.
- Make sure that your developer has not been not left opened or in a hot place. Exposure to heat will degrade its lifting capability.
