Big questions about hair dyeing (9) DIY hair dyeing

Do not buy dyes indiscriminately. Using dyes indiscriminately is a super scary thing. If it is not necessary, it is recommended to go to a beauty salon to dye it, which is safer and more reliable.

If you really have to do it yourself, you have to dye it yourself, so save this article and study it carefully.

Let's first look at what your target color is, and how many degrees of color you want. There must be a number on the dye cream, which belongs to # international standard code.

We are internationally renowned #LOREAL# Laiya For example, chroma and lightness are the numbers before the decimal point, and the numbers behind the decimal point are called hue and hue.

# Chroma: 1 black, 2 very dark coffee, 3 dark coffee, 4 coffee, 5 light coffee, 6 dark gold, 7 gold, 8 light gold, 9 very light gold, 10 very light gold

# Hue: 1 gray blue green, 2 purple, 3 gold, 4 copper, 5 bordeaux, 6 red, 7 green

After remembering those numbers, we can quickly and easily choose the target color we want.

For example, 6.1 is dark gold with gray, and 7.23 is gold with purple gold.

Remember to wait for the class exam.

Next is to look inside the package, there are several % attached# dioxygen milk, if you want to be professional, it is recommended to go directly to the beauty store to buy, so that you can freely choose the number of %, that is, the concentration of dioxymilk is expressed as a percentage, and sometimes it is also marked as #vol.

The % of dioxymilk refers to # concentration, vol means # oxygen content We call it degree.

Different concentrations have different functions and operating residence time. Let me make a brief introduction with the corresponding distinction:

3% 10vol: including those below 3%, such as 1.8%, all of which are used for coloring from light to dark.
The most important thing to be careful is that after bleaching, it is best to use 3% for coloring, not because the bleaching is not light enough, if you use dye cream and 9% hydrogen peroxide when coloring, it will make your color not enough # saturation, which in turn is super easy # fade.

6% 20vol: dyeing depth ± 1 degree, the same level of dyeing and coverage # gray hair use.

The so-called dyeing at the same level means the same chroma, but you want to change the hue; if you want to change the original 5.3 color to 5.4 color, then you need to use 6%.

Regarding the part of covering gray hair, don't use 9% just because you want to dye a lighter color. Even if the dye cream is really successful in coloring, the mechanism of hydrogen peroxide milk to automatically fade two degrees, at this time we call it # Crash Theory.

Because at this time, I don’t know who to listen to for the dye cream and hydrogen peroxide milk. The most common thing is that the gray hair will automatically transmit light within two days of coloring.

9% 30vol: for 2 degree fade.
Remember that it is fading rather than saturating the color, it is only used to lighten the chroma and lightness.

12% 40vol: for 3 degrees shallower. The reason is the same as 9%.

Different concentrations have different residence times. Let me teach you the simplest and easy-to-remember method, that is, add 10 to the degree of oxygen content, which is equal to the required waiting time.

For example, 10VOL plus 10 is equal to 20; therefore, 3% 10VOL hydrogen peroxide emulsion is prepared together with the dye cream and applied to the hair for coloring, and it needs to stay for at least 20 minutes.

If it is modulated by 9% 30VOL, add 30 to 10 to equal 40, so the dwell time cannot be less than 40 minutes.

The stay time mentioned above is based on # stands still without heating Calculated in principle, if you have a machine that can heat, of course you can make the oxidation rate faster to shorten the time.

Make sure that the target color you want is at a few degrees, and then look for the hue you need.

Usually beauty stores will have # color card, you can directly pick it up and put it on the hair for comparison. If the hair itself is closer to the brightness, the easiest way is to ask the boss to help you see it.

If you want to quickly dye lighter at one time, you can choose 12%, which is more suitable for your needs. # high reward usually accompanied by # High Risk, if your own hair has been very light before, and you still choose 12%, you are looking for death at all, and your hair will definitely rot immediately for you to see.

If your natural hair is thicker and thicker in diameter, you can buy some bleaching powder to remove some melanin pigment before applying the target color, which will allow you to achieve the desired target color more quickly.

# bleaching powder Use with hydrogen peroxide milk, one-time lightening can reach # up to five chroma.

For example, if you want to apply a color of 8.3 today, but after comparing with the color card of Meicai, the original hair color is 3 degrees, then you need to fade it to at least 5 degrees.

If you want to be on the safe side and make the color to be applied later more saturated, it is best to fade to at least 6 degrees of color first, and then apply the color.

After everything is clear, it is time to prepare the dye cream, apply it to the hair and wait for the time to see the result.

If the application exceeds the limited waiting time, the effect will start to change # invincible slow, although the effect is slow, the degree of hair damage will not become slower.

Basically, if the time is too long, it can only make the hair quality worse and dry, and then it looks like this # wrong hair coloring, no matter how you use it to repair it later, it is still easy to fade quickly.
I think normal people should not be willing to fade their hair too quickly just after dyeing, and then the hair turns into # Straw Bar!

When you go to a hair salon outside to dye your hair, if the stylist tells you that the color has not passed and let us wait, usually more than half of the probability is just # speech You, the most common thing is that the hair stylist is not professional and incidentally ignorant, which makes your hair continue to be damaged!

So if the time has passed for a long time, but the result has not reached the target color, the best solution is to put the whole dyeing ointment # scrape off and reapply Don't stop at the hair and continue to destroy it until it is dry, but it still doesn't reach the target color.

Speaking of this, almost everyone should already have relevant knowledge, know how to choose dyes and basic operations!

It is not recommended to dye your own hair as a last resort, and it is really dangerous to buy dyes indiscriminately. If you really want to buy it, you can go to a beauty store to buy it, and when there are too many brands and you don’t know where to start, the easiest thing is to see if there is any L 'OREAL,1TP5 TWELLA,# Goldwell,#Schwarzkopf The world's four major hair products, if you don't know what to buy, just buy these, at least it's safer!

I really don't know much about the open frame, but in terms of safety, I only recommend L'OREAL.

Do not buy indiscriminately, or it will be fine if you don’t get the desired target color, if you are not careful # allergic reaction Turning into a pig's head, or drying out the hair is not worth the loss.
