How To Bleach Hair/ Lighten & Tone Hair at Home (bleaching)
How does bleach work?
Hair Bleach consists of two different products that are mixed together before use:
Bleaching powder which consists of brighteners thickeners and alkalizing substances among other compounds
Developer a solution of hydrogen peroxide
It is worth noting that both the powder itself and the developer are brighteners, but this combination is especially special because their combination provides two vital functions
The powder becomes moist accelerates chemical reactions and alkalizing agents activate the developer causing it how to bleach hair to start oxidizing everything it touches.
This whole process becomes even more inventive when you consider how it affects the structure of the hair. Regular hydrogen peroxide can lighten hair on its own but the effect is surprisingly mild.
It also cannot penetrate very efficiently into the hair due to the environmental contraction of the cuticle of the hair shaft. However the slight alkalinity of the mixed hair bleach not only activates
The peroxide but also opens the cuticle layer allowing the bleach to penetrate the bark of the hair shaft where it oxidizes the pigment melanin, which forms your natural hair color.
Now that you know a little how hair bleach works it’s important to discuss the individual components of the product.
In particular it is very important for the developer to understand because he has different strengths
How to bleach hair and this changes how strong the mixed product will be. Strengths although often measured as a percentage are better known as developer volume.
|5 volume||1,5%||Semi Permanent Dyes|
|10 volume||3%||Permanent dyes bleaches, whitening baths|
|20 volume||6%||Permanent dyes, bleaches whitening baths|
|30 volume||9%||Permanent dyes bleach (usually outside the scalp )|
|40 volume||12%||High lift paint, some persistent dyes very rare when bleaching outside the scalp|
Whitening on scalp and scalp will be explained later in this article and the maximum number of developers is explained for each brand.
Using the table above you will get an approximate idea of the use of each volume for the developer since it applies to all hair coloring both lightening and coloring.
However, it is important to understand that in almost all cases a larger volume of developer will produce more lightening over a certain period of time.
Due to the fact that it also causes more irritation to the scalp and possibly more damage how to bleach hair .
There are also brand specific differences that will be discussed later when you can use 30% by volume of the Developer on the scalp with one bleaching powder but with the other it is either not recommended or not even recommended.
There are reasons for this that are due to the bleach formula for hair so it is important to understand the individual product that you have chosen in the context of more general rules.
Hair Levels and Tones
All hair from black to the lightest blonde gets somewhere in the international color code system (ICC) how to bleach hair Black hair is usually defined as the first level and all this goes up to the tenth level which is an almost white shade of the blonde.
Although there are some differences in the way different brands use the level scale they are usually small and small rather than overly harmful differences.
Now that you know how to classify the darkness of your hair, it is useful to discuss the bleaching process itself what is their depth. how to bleach hair
The color of your natural hair consists of the main pigment under the color that you actually see and this contributes to the depth of the color making it dark
In fair hair, this basic pigment is from pale yellow to golden orange. However black hair has a deep dark red base.
When you bleach your hair, the visible color is removed to show the main pigment, and you can estimate how much lightening happened by looking at the base color that you came to.
You can also use the base color as a guideline to determine the level of toner that you should use and what color you can achieve after toning is complete.
As an example of how you could use this information, if you determine that your current hair color is the fifth level.
And you can reliably raise it to three levels with the bleach that you prepared the easiest level that you can reach eight.
Then you can see that your hair has turned dark yellow which tells you that it is right.
Now that you know what level you have reached, you know that you need the eighth or ninth level ash toner to neutralize this yellow pigment to a natural light brown color.
In fact the table below is your cheat sheet for achieving any new hair color. This gives you the knowledge that you need to know if the goal is reasonable how to bleach hair
Combined with knowledge of the scope of development and even what you need to look for to know that you are on the right track as well as the right shade of the dye that you need use. then used as a toner to finish your new hair color!
10 Things You Probably Didn’t Know About bleach hair.
Lift Potential Bleach
A number of factors affect the effectiveness of the product when bleaching hair. Some of the most important factors include:
Hair porosity how susceptible your hair is to the absorption of dyes. Porous hair is whitened more often because the product gets into the hair more easily due to weakening of the cuticle.
The opposite situation is persistent hair which is supposed to be more resistant to bleaching.
The volume of the developer has a fairly linear effect on hair whitening a larger volume means more lightening.
Whitening Powder The specific whitening powder you choose to use can significantly affect how much light you can achieve.
For example there is a significant difference between a powder with boosters or a common common powder.
Heat the warmer the temperature of the bleach the faster it reacts with your hair. This often leads to the use of wrappers or hoods on rather dark hair or where additional lightening is desired.
Water quality It is interesting enough that the quality of water with which you regularly wash your hair affects hair bleaching.
Water with a high content of metals such as iron or copper causes these metals to be found in your hair at concentrations higher than expected and can actually catalyze bleaching
Causing them to react more quickly and aggressively. Sometimes a shampoo is used in advance if it is known to be a potential problem.
|Peroxide Concentration||Raise potential|
|10 volume||1 – 2 levels|
|20 volume||2 – 3 levels|
|30 volume||3-4 levels|
You really need to use bleach?
Before you start using bleach, decide whether you really need it whether it is the best way to work and other factors such as the condition of your hair.
For example, no matter how much you want a new light hair color your hair can only damage so much.
Depending on how coarse your hair strands are, more than you expect but you will still notice a deterioration in their appearance
Even before any damage occurs so it is important to remember the health of your hair before using the product.
Other factors to consider include:
- How many levels do you want to lighten your hair?
- Have your hair been dyed before?
For a new color that requires 2–3 levels of lightening you can usually achieve this result using a dye with 30 or 40 vol.
Depending on the initial depth and whether your hair has been dyed before.
Hair that has not previously been dyed is usually called virgin and it will be lightened with a permanent dye with a large developer volume.
Hair that has already been dyed will be significantly more stubborn which will require the use of other products such as a hair dye remover bleach or whitening bath depending on how much brighter you should be.
However this is somewhat beyond the scope of this article since it is more in the territory of color grading.
In general consider that natural hair is a good candidate for lightening with paint if you need only 2-3 levels of lifting. Significant light very dark or dyed hair usually requires bleaching.
Normal VS Hair Salon Bleach
There are two different types of bleach and your choice comes down to some combination of budget and desired results.
Universal products work just fine but the problem with them is that you get less lightening from them compared to some high end brands
Which include amplifiers and softening damage components that allow bleach to more effectively lighten from a smaller volume. the developer.
For example products such as Igora Rapid Blonde or Wella Blondor with a 20 volume developer usually outperform conventional powder with a 30 volume developer.
Honestly when it comes to the condition of your hair I would recommend spending a little more on a better product because it will also lighten more efficiently
But there is no real problem with using cheaper powders just understand that depending on how dark it is you have hair and how much lifting you need.
You may have to bleach twice with one of these powders or with a large developer volume longer duration.
Hair Whitening Preparation
You must have a goal before bleaching your hair. By combining the concept of depth levels and the lifting potential of various concentrations of peroxide you should come to an estimate of how much lifting you can achieve.
When bleaching hair and this will help you avoid mistakes and will not have unrealistic expectations when using. product.
Here of course there is some variation of the brand and often the product indicates what benefits you can expect from a certain amount of the developer.
To prepare bleach you will need a standard bowl for dyeing hair and a tinting brush.
Mix the powder together in a one to one bleach ratio and the peroxide concentration of your choice unless the brand you are using indicates a different ratio.
The product must be prepared and then immediately used, because a chemical reaction occurs and the product loses effectiveness when you leave it alone.
Always use gloves even when mixing only bleach. Although this will not work for most people if they get a little on their hands and do not have too long
Some people have more sensitive skin than others and it’s just a good practice to protect your hands as a whole when using any chemical product.
Simple steps applying bleach
When using bleach, faster application will reduce the likelihood of uneven results. To quickly apply it there are a number of different methods of sectioning and application.
Which are often based on personal preferences. The simplest and most reliable for most people would be to divide the hair into four sectors.
1-To divide your hair into squares all you have to do is divide them both in the center and again from ear to ear. Try to make these sectors roughly the same.
There is a bit of practice in this but the general points given above are a good reference point for work if necessary adjust them depending on the shape of the head.
For long or very thick hair you can use crocodile clips rather than a flat hair clip.
2-After you have four quadrants, all you have to do is work on them one at a time quickly moving relatively thin sections of hair from top to bottom, staining with bleach from the root to the root of the hair. along the length and tips.
3- Apply less bleach very close to the scalp. This happens for two reasons: it will cause less skin irritation and reduce the risk of “hot roots” when heat of the scalp leads to more discoloration of the scalp.
Do not worry, the moisture of the product will allow it to crawl all the way and properly cover the root area although less densely than if you put it there with a brush.
Alternatively if you do not have enough time or have problems not covering too many roots
Wrap it all up after you cover all the hair and then this is not a problem because the heat will be balanced.
4. As mentioned above you can wrap the hair at the end, and this will lead to more lightening because the whole preparation remains warmer.
Some brands advise against this so consider this regarding your brand. As a rule more aggressive powders are products that should not be wrapped.
On and off scalp Bleaching
The time during which you leave the bleach for processing depends largely on your goal. The only thing to remember is that it should not be left longer than 45 minutes in most cases and for most brands.
If by this time the bleach has not picked up enough pigment you will have to do another application or check with a brightening dye and this should not be done for at least a week.
This should also be repeated only if your hair is still in good condition.
There are three main reasons why you need to rinse the bleach at a certain time or less depending on the brand used: effectiveness, damage and irritation.
The reaction that allows the bleach to lighten hair actually slows down quite suddenly just as it builds up quite suddenly after application.
This is due to the fact that by this time most of the reactive oxygen has already been released.
If you kept the bleach in your hair longer than recommended all you really do is intensify the irritation of the scalp and do more damage to your hair
Because the hair is kept in an alkaline state which over time weakens them structurally and makes them more than susceptible to damage the longer the bleach remains.
Damage to hair damages not only oxidation but also elevated pH and humidity.
If the bleach has raised enough pigment to the recommended maximum time interval immediately rinse it to stop the process and avoid further damage or lightening.
Care must be taken to monitor bleach to avoid over processing, and you should check it approximately every 5-10 minutes while it is being processed.
Rinsing and strengthen
Rinse the bleach thoroughly with plenty of cool water before washing your hair with shampoo.
Any bleach that does not wash off can potentially damage your hair and also cause skin irritation so it is important to make sure that it is completely removed. Rinse hair twice to remove residue.
If you intend to apply dye or toner immediately avoid using conditioner as it closes the hair cuticle and reduces the penetration of the dye and neutralizes any unwanted colors present.
This is a generalization, but it will suit most people. The paint that you use to tone your hair is 1-2 levels lighter than the level you bleached with an ash tone.
For example if you bleached your hair to level 6 and it was a dark golden orange, you would use 7A or 8A to tint it. If you bleached your hair to level 8 and it was yellow you would use 9A or 10A to tint it.
The dye will match the base tone of your hair because of the level chosen in the darker example it is a darker dye and contains mostly blue pigment to deal with orange tones while the lighter example is purple.
The only time this does not work is if you bleach previously dyed hair and it continues to look orange to brighter levels than it should be due to the presence of artificial pigment.
From a technical point of view this is a technical color correction and to give some idea without being too distracted
The correct way to solve it is to take a lighter dye and add even ashes or a reasonable small amount of a pure blue tone if the brand has it.
After toning rinse the product and then you can use the conditioner to neutralize the remaining alkalinity and fix the color on the hair.
For hair that seems really coarse you can also mix a small amount of white vinegar with some conditioner and this is an effective way to close the cuticle and return the hair to its natural balance much faster.
This will help to make your hair smoother and shinier and also reduce the fading of the new hair color.
Whitening should not end with a terrible story and should not damage your hair. To achieve the best results and preserve the integrity of your hair do not forget about safety.
When using and apply them only to hair that is not yet damaged. If you look after your hair like that they will be grateful that they look their best every day.
