Explained simply, the difference between bleach and ordinary hair dye is whether or not there is a process of removing color.
When bleach is used, hair’s pigment is removed in advance in order to improve the color production of subsequent coloring.
In contrast, when ordinary hair dye is used, a color agent is applied over the current hair color without changing that color in advance.

In addition, in the case of ordinary hair dye, the original hair color and the color of the hair agent mix and produce color, and therefore one of the characteristics is that there often are individual differences in the color nuance after completion.
In the case of bleach, the production of color changes depending on the amount of melanin that is removed, but because it is not affected by the original hair color, there is not much individual difference.

Hair dye does not remove color from hair, and therefore the hair coloring that is possible is a comparatively darker and subdued color nuance.
It is said that it is possible to lighten hair up to a tone of approximately level 9 to level 11 by using hair dye one time.

Bleaching and double coloring seem to be the same thing at first glance, but bleaching refers to removing color from the hair, and double coloring refers to a technique of conducting coloring by dividing it into two stages.

As the way of conducting double coloring, the two types that are generally used are a method of using bleach and a method of not using bleach.
For double coloring that uses bleach, color is first removed from the hair by using bleach, and then ordinary coloring is conducted.

For double coloring that does not use bleach, the general way of doing it is to use an ordinary coloring agent that is not bleach to dye the hair as light as possible and then use another coloring agent to add color nuance.◎
Because color is not removed, it is not possible to achieve a color that is as light as when bleach is used, but the range of coloring that is possible is broader than that of ordinary hair dye.
It is said that it is possible to lighten hair up to a maximum tone of level 13.

Three points that should be paid attention to when bleach is used for the first time

Bleach makes it possible for hair to be dyed to the ideal color and for people to easily change their image, but there are of course also points to which attention should be paid.
In particular, please be careful if you will receive bleach treatment for the first time!
In order to enjoy beautiful bleached hair for a long time, please be sure to check these points before you receive treatment.

POINT1. It is easy for hair to become damaged.
POINT2. Color fades quickly.
POINT3. Understand your hair’s history.

You said, “I have repeatedly used hair dye and dyed my hair black, and the end result is that I now have black hair,” but for hair that has been dyed black (including dyeing to cover gray hair), if only ordinary coloring is conducted, production of color in the places that were dyed black in the past may be dull and there is a strong possibility that you will not be able to come close to the lightness that you imagine.
If you want to change your current hair color to a lighter color nuance, we think that in the end it will be necessary to use bleach or a dye-removal agent to remove color.
If you have dyed your hair black or used a dark tone of dye to cover gray hair for a long period, even if you want a lighter color the next time or thereafter, there is a possibility that one instance of coloring will not make it possible to dye your hair as light as you want it.

In actuality, a guest who had been dyeing her hair a dark tone (dyeing to cover gray hair) for a long time took a long period of one-and-a-half to two years (conducted planning) and then finally was able to come close to her ideal light hair color.
In a case of conducting lightening again on hair that has been dyed a dark color once, if it is dyed by bleach or dye to cover gray hair, a special chemical agent called a dye-removal agent will be used.
Work to remove black-dyed pigment or darkly-dyed dye pigment will be necessary.
For that reason, please understand that even if you ask a salon for a high-lift color design using only coloring, it is difficult to attain a light color through one instance of coloring, and coloring treatment will be conducted a minimum of two times.

As for dying your hair yourself, we absolutely cannot recommend it.
There is no question that you should have your hair dyed at a hair salon.
You said, “I am considering using a store-bought coloring agent to dye my hair myself,” but “dying your hair yourself at home by a treatment that uses bleach or a dye-removal agent” is a difficult treatment with considerably high risks.
If the work of “removing the black dye components and then adding color nuance” is conducted in the guest’s case for which we received an inquiry, the risks and degree of difficulty will be high, and therefore we unquestionably recommend treatment at a hair salon.

You said, “I always try to take care of my hair, and so my hair itself has luster and I think it is healthy,” so we think that you are probably reducing the burden on your hair and trying to regularly take care of damage and otherwise take care of your hair…
However, if you repeatedly use hair dye after using bleach or a dye-removal agent, a considerable burden and damage will arise for the healthy hair that you work so hard to maintain.
If you prioritize your hair’s state of health, we think that there is also an option of not aiming for such a light color nuance and finished result and not conducting bleach coloring (double coloring) until the portions that were dyed black are cut off and no longer exist.
Please consult a hair stylist who you trust and consider a color plan for the future that matches the order of priority for your style.

The level to which hair can be lightened by using bleach the first time is said to be up to a tone of approximately level 14 to level 15.
However, this is if the hair before dying was hair that had never been dyed.
If you have been using hair dye repeatedly thus far and your hair is already lighter than your natural hair, it is probably also possible to raise the tone somewhat more by using bleach one time.

Bleach places a heavy burden on the scalp and hair, and therefore it is particularly easy for people who use it for the first time to feel pain.
There is a tendency for people to no longer feel such strong pain once they get used to it.

The differences between bleach and care bleach are the degree of damage to hair and the length of time that color lasts.
Care bleach contains moisturizing ingredients that protect hair, and therefore damage after bleach is conducted can be kept to a minimum.
Hair’s overall luster is also different, and hair will probably feel quite smooth when you run your fingers through it.
The color will also last longer, and therefore it is possible to maintain a longer period of the beautiful color nuance of freshly dyed hair.
