Introduction to the topic
As a hairdresser, I can only tell you to stop messing around with your hair.
However, despite the fact that “it will grow” is a popular phrase, I have witnessed women on the verge of tears and panic attacks after bleaching their hair without consulting a professional.
After a bad bleaching job, your hair will grow back, but you’ll have to live with the damage for the rest of your life.
Hair loss, burns to the scalp, and split ends are just a few of the side effects of bleaching that can go awry.
Using a 30 or 20 volume developer, I’ll show you how to lighten your hair as safely as possible.
How do you know which developer to go with? 30-volume or 20-volume?
Hair tones are an important topic to cover before we get into the process of bleaching our hair.
From black to blonde, there are ten different shades of hair colour that range from number 1 to number 10. The developer you use will depend on the colour you want to achieve.
To subtly fade light-colored dyed hair, use a 10 volume developer. The difference is almost imperceptible. If you want to lighten your hair from dark to blonde, this is not the method for you.
If you only want to lighten the colour by two or three shades, a 20 volume developer works well in light brown hair.
In order to lighten your hair three or four shades, use a 30 volume developer. [/su highlight] However, you must be careful with the application time because you could injure your scalp.
The Snow Queen’s hair could be lightened with a 40 volume developer, but it’s extremely harsh on your hair. Please don’t take the risk of becoming a victim of your own tears by venturing into those waters.
That’s excellent work.
Let’s get started with the process now that you know which developer to use based on the look you want to achieve.
Bleaching powder is necessary for developers of 30 and 20 volumes.
Gloves should be worn whenever possible to protect your hands and fingers.
What are the significances of the various levels of development?
The oxidising capacity of the developer is simply denoted by the hair developer levels.
Because of its minimal effect on the cuticle and its use with semi and demi-permanent colour lines, 5 volume is a less frequently used developer. For ‘deposit only’ results, many colour lines allow you to use their permanent colour with 5 volume.
The hair will no longer be virgin and will shift its natural shade, but it will not cover or lift grey hairs. It will not be virgin hair. It serves as an activator for the colour and is typically found in developers for glazes and toners. For fragile baby hairs that only require a 1-2 level lift when bleach is used, 5 volume can produce a very slight shift in the hair.
The 10-volume developer is designed to be used when applying colour to hair of a similar lightness level. It works by allowing the colour to deposit and penetrate the hair strands by opening the cuticle layers. It has 3% peroxide in it.
Cuticles are lifted by up to two levels when using a 20 volume developer. The 20 volume developer works best if your head is covered in a non-uniform distribution of grey hairs, for example. Peroxide at a concentration of 6% is found within.
Permanent hair colour can be lifted up to four levels with a 30 volume developer, depending on the texture of the hair. In addition, it can be used to camouflage grey hairs on hair types that are more resilient. The cuticle will be blasted unnecessarily if thirty volume is used for basic deposit only colour.
Using 30 volume with bleach and foils may result in over-processing. For open-air processing, where heat is less of an issue, this developer is better suited. Applications with a 30 volume should never be heated and should be monitored regularly, ideally with a test strand.
Permanent hair colour and high-lift colour can be lifted up to four levels with the use of a 40 volume developer, which can be used with both. A 40 volume developer’s ideal processing method is balayage, which allows for maximum lift but less control over heat. It’s a dangerous combination: bleach, 40 volume, and foils.
Due to the popularity of hand painting techniques, developers of 50 volume or more have grown increasingly popular in recent years. We must be cautious and always consider the desired outcome and the integrity of our client’s hair, no matter how trendy these may be. Using these developers with foils or colours is not recommended.
How to lightening your hair with 20 volume developer in easy steps?
- Bleach powder and developer should be mixed in a 2:1 ratio in a bowl, depending on the amount needed to completely bleach your hair. This ratio should be maintained.
- Divide your hair into two large sections, then work with each section individually. First, we’re going to work on the part that is directly beneath it.
- In order to get the best results, use a brush to apply your bleach mixture to the ends and the length of your hair first.
- Allowing your roots to air dry for the final ten minutes ensures that the lighter ends of your hair match the colour of your roots perfectly.
- Make a second pass over the top after you’ve finished the bottom.
- Take a shower cap and cover your head for fifteen minutes.
- Make sure to check on your hair every three minutes and never leave the bleaching mixture on for more than 30 minutes.
- Wash your hair thoroughly and avoid using sulfate-containing shampoo after the time period has passed.
- No heat source should be used when drying hair.
- You can use purple shampoo if you notice yellow streaks in your hair that are just plain awful, like chicken yellow.
Using only developer in your hair, what happens?
Lightening your hair with 20 volume developer will result in a lighter shade of hair colour. In order to get good results, you must keep the developer wet and apply heat to it at all times. As you can see in the previous section, this can be a difficult task.
How much you need lighter after using 20 volume developer to hair?
You now know that using a 20 volume developer will lighten your hair by one shade. Then, what about the rest of the developer’s output? Your hair’s lightening effect will be reduced if you use a 10 volume developer. The more you increase the octane, the more your hair will lighten.
It all boils down to the developer’s peroxide content.
In this case, 20% volume = 6% peroxide
90% peroxide by volume is equal to 30 volumes
Peroxide at a concentration of 12% in a volume of 40 litres is 40 vol.
If you want to lighten your hair, the higher the volume, the more you should use.
When bleaching your hair, peroxide alone isn’t going to get the job done as well as using a mix. Because peroxide is acidic, it doesn’t swell the hair, making it less likely to break. The alkaline peroxide in all commercial hair lighteners is used for this very reason. Adding alkaline hair colour to peroxide activates the oxidation process, resulting in a more effective lightening of your hair.
What are the Pros and cons of using 20 volume developer to lighten hair?
Now that you understand how developer works to lighten hair colour, let’s talk about the advantages and disadvantages of using developer-only. Lightening your hair without bleach has both advantages and disadvantages.
Here are some of the reasons why you might want to lighten your hair colour without using bleach.
- To begin with, the use of this dye produces beautiful colours. The hair colour transformations are long-lasting and intense.
- In addition, it paves the way for the removal of natural hair colour pigments by unlocking cuticle overlap points of intersection.
- In addition, the developer allows for colour changes to be made. It accomplishes this by releasing colour while also allowing pigments to fall into the cuticle layers.
- There are no worries about a colour trickle when using developer because the fusion it forms with hair colour is consistent.
- Using a lower-volume developer, such as 10 or 20, can cause less damage to your hair than using a higher-volume developer. The cuticle layer isn’t opened as much by low-volume developers, so less damage is done to hair strands.
- Finally, the developer is added to the hair dye to make it work.
Here are some of the drawbacks of using developer to lighten your hair colour.
- Hair, scalp, and skin can be permanently damaged if you don’t understand the chemistry behind lightening your hair. Hair that is rough, porous, frizzy, dry, and prone to breakage is the “best case” scenario for developer damage. Chemical burns to your scalp and skin are the worst-case scenario. Before attempting this method, be aware of the risks.
- The natural melanin pigments in your hair are oxidised by the peroxide in developer, resulting in a permanent change in the colour of your hair. So, until you cut, bleach, or dye your hair a different colour, the colour your developer gives it will remain in your hair. Permanent results are a major drawback if you don’t like them.
- If you have dark hair and want to go blonde, developer will only give you a 1-2 level lift. When using a developer without bleach to lighten your hair, you can only go up to two levels. Many people aren’t able to get the results they want with just one or two levels.
- If you lose track of time while the developer is sitting on your hair, you’re going to do some serious damage to your hair and scalp. Although 30 minutes is the maximum time recommended by experts, 20 minutes is a safer cutoff time.
