A few questions about hair dyeing, thank you!

Dye your hair for about a month and a half, and the hair roots will grow about centimeters of new hair, if the color of the previous dye is not too light, the contrast is not large, depending on the specific situation; However, the previous dyeing of the shallow 1, the contrast between the new hair and the first dyeing is greater, it is ugly, it must be supplemented, but there is no need to dye it all, only the part that grows can be dyed, which is called "mending roots" in the industry. Generally, the root patching is about the same as dyeing a short hair on the whole head, and you can measure it by this. Washing more hair promotes the movement of scalp capillaries, sebaceous glands, hair follicles and associated nervous system, which is equivalent to massage, and the hair naturally grows a little faster, but at the same time, the shampoo more or less harms the epidermis and accelerates the metabolism of hair follicles, if the physique can not keep up with the nutrients and speed of its metabolism, it may cause hair loss.

Besides, wash your hair frequently after dyeing, and the color will fade quickly. Therefore, maintaining a normal shampooing frequency is beneficial and non-destructive.

The upstairs is very precise, and it can be seen that it is a technician-level figure in the industry. However, there are a few local words missing, I will add: in a month and a half, about 2 centimeters of new hair has grown, and the roots are about to be filled.

**Somewhat different, is the relationship between the region and the salon level. When it comes to level, in fact, it has nothing to do with technology, it is the location environment, store area, decoration grade, equipment and hardware, etc., and the cost of each item is related to the price. The rest of the upstairs has been made clear.

Hair dyeing and fading is inevitable, and hair dye itself is an oxidizing chemical, which will gradually fade as long as it comes into contact with air, and of course it is also related to the number of times you wash your hair and shampoo.

Uneven dyeing is still a problem of operation, your hair tips are called mature hair that have been dyed before, and it is easy to color again, and the root part of the hair is newly grown hair, and your hair quality should be very good (coarse, hard), which is not easy to color.

If you are doing it at home, it will be effective to dye the roots of the newly grown hair that have not been dyed before, and then dye the ends of the hair.

It is more difficult to grasp the time if there is no color difference at all, and it is up to you to figure it out by yourself Hehe.

Another way is to comb the hair growth area with the B agent (hydrogen peroxide) in the hair dye first, and then dye it all.

Oh, and what color do you dye, and the next time you ask a question, you have to say it so that it is easy to answer

I am a professional hair product, and you can find me if you have any hair-related problems.

Inconsistencies between the inside and outside are inevitable, and dyed hair will become more and more reminiscent of your original hair color over time because of the shampoo. In addition, the hair on the outside will start to turn orange when exposed to ultraviolet rays, and the hair on the bottom will not be so it will only darken. When dyeing your hair, it is obvious that the underlying hair will make the underlying hair lighter, and the hair color will become more even in the future.

If the hair color on the top of the head is lighter, it is obvious that the hair underneath is easier to apply because the scalp is hot.

Is the color difference big, it doesn't matter if it's not big, because the hair outside is always the most injured, the ultraviolet irradiation air oxidizes, the color will be light, it's normal, and then dye the hair, it can be dyed into a consistent color, it doesn't matter if the color difference is not big, if the color difference is large, it is their technical problem.

Hehe, I'm the one who opened the barber shop It's the first time your hair is dyed black, and the black hair can no longer be dyed with color oil, if you want to dye it, it's best to fade first, that is, take bleaching powder + 12% hydrogen perfume + shampoo + conditioner and then dye the color oil after fading, because the artificial pigment particles in the hair are large and not easy to fade, and the color oil pigment particles are small Only when washing hair does it love to fade, Lunshidu Lucido-L's hair dye cream No problem It's a mistake in the operation of their store, and generally short hair is not willing to do fading treatment Idle trouble.

Change stores, dye can also be tried by changing the brand, German Goldie.

Anyway, this store has this problem in the end after dyeing, so let's change it.

Nourish it with a hair mask I also have a dye cream in the store I haven't heard of you yet.

No! I've had this situation before, the staining was uneven, and I wanted to re-stain it, but many people told me that if you re-stain it for a short time, it may not be colored, because your cuticle is so damaged that it doesn't lock the color anymore. And your hair will be like dead grass and you won't be able to get it.

Because of this, I have also checked a lot of information, a person should dye their hair normally twice a year, at most four times, dyeing too often will cause dry hair, not easy to color.

Classification

Hair coloring is divided into plant and chemical properties. The characteristic of the plant is that it does not harm the body, and the disadvantage is that it has a single color. Chemical hair dyes are highly polluting and damaging to the blood system.

Plant-based hair dyeing has gradually been accepted by people, and there are more and more institutions promoting and researching plant-based hair dyeing.

Chemical hair coloring changes the structure of the hair and the process of eroding the scalp, ammonia corrodes and damages the hair follicles. Plant hair coloring is a physical process in which nourishing elements attach to the hair and scalp like a membrane, nourishing and caring for the hair and nourishing the hair follicles. Just like a cut apple that is covered with an oxide film for a while, botanical hair coloring uses a physical oxidation process to attach nourishing ingredients to the hair and scalp.

The hair dye paste is made with the target color (the color you want to dye) and hydrogen peroxide. The ratio of the blend depends on the target color and the undertone of the hair. Most color blends other than tool colors can be blended in a one-to-one ratio with the target color and hydrogen peroxide.

Example: Octave yellow hair undertone.

Target color 6 45 (burgundy).

Formula 6 45+6% hydrogen peroxide, the ratio is three to two.

The undertone of the hair is black.

Target color 8 33 (reinforced yellow).

Formula 8 33+12% (hydrogen peroxide), the ratio is one to one.

If you are doing tool colors (blue, purple, green, white, gray), you need to fade your hair to more than 9 shades, and then dye your hair, according to different colors and different hair base colors, to make corresponding adjustments.

It is best to blend the paste under the guidance of a professional hairstylist, because everyone's hair type is different, and the method of color blending must be modified accordingly, so only an experienced hairstylist can accurately blend the correct paste.
