Hair dye is a type of cosmetic product that dyes hair. It is divided into temporary, semi-permanent, and permanent hair dyes. Hair dyes generally contain p-phenylenediamine, a carcinogen, and experts say that p-phenylenediamine is a colorant that must be used in hair dyes and is an internationally recognized carcinogen.

According to the CCTV international network survey, among the more than 2,600 people surveyed, more than 90% of the people who have dyed their hair have been dyed, and about half of the people who started dyeing their hair before the age of 30 were surveyed.

Hair dye cosmetics have the effect of changing the color of the hair, commonly known as hair dye. Chinese belong to the yellow race, and most of them use white hair to dye black for beauty, so hair dye is also relatively monotonous. Europeans and Americans are accustomed to bleaching or bleaching their hair first, and then dyeing their hair blonde, yellow, flax, reddish-brown, violet, etc., so there are many varieties of hair dye.

Since the reform and opening up, under the influence of international popular hair color, China has also successively launched various shades of color hair dye, making China's hair dye market shine. In the 21st century, China will enter an aging society, with the gradual increase of the silver class, the market demand for hair dyes will increase day by day. Moreover, in today's society, the pace of life is fast, the work is intense, and the gray hair and hair loss caused by the tension and busyness have increased significantly, which has brought a huge market for hair dyeing products.

Hair dye contact**, and in the process of dyeing hair, it is also heated, so that the organic matter of benzene enters the capillaries through the scalp, and then reaches the bone marrow with the blood circulation, and repeatedly acts on hematopoietic stem cells for a long time, resulting in the malignant transformation of hematopoietic stem cells and the occurrence of leukemia. One of the reasons why hair dye can cause allergies, leukemia and other diseases is because hair dye contains a chemical called p-phenylenediamine.

Yes. And a lot. Overlord yes, my dad bought it at the supermarket.

There are supermarkets, but you don't have them. Then go to the wholesale market, there must be. Most online.

As long as you go to the supermarket, you can generally have it, no matter how big or small. Small supermarkets also have to do business.

The price is generally about 100 yuan, this is a general hair dye, a bad hair dye is dozens of yuan, a good one is much more expensive, it is recommended that you go to the barber shop to dye it, it is cost-effective and not troublesome.

Go to the supermarket and buy it, it's all there. Much cheaper than a barbershop.

1) Don't use conditioner when washing your hair, it's best to use soap. You should know that the role of conditioner is to keep the cuticle of the hair in place so that the hair will be smooth. So let's do the opposite now, let him open up, so that the hair dye can get into the hair and color.

After washing your hair, you must dye your hair thoroughly and then dye it, the barber shop is very lazy, and it is generally dyed without blow-drying, and if you ask him, he will not say that it will affect the effect, but in fact, it will affect.

2) Find a few clips to pinch the hair, dye it separately, start to comb down 3 4 cm from the root of the hair until the end of the hair, and repeatedly touch the hair cream. And then there's the other part. After all the hair is applied, it is the root of the hair, because the temperature of this part is high, it is easy to color, and if you dye it together, the top of the hair will be brighter than the bottom of the hair!

After all the dyeing, if you have to touch all the drafts left, you can also massage them with gloves.

4) Roll up the hair and wrap it in a plastic bag, wait for the time as indicated, if you want a more visible color, you can warm up the hair and wrap it around with a hot towel. In fact, the easiest way is to go to the sauna in the bathhouse to steam, hehe, the effect is good.

5) If you want good results, then try not to wash your hair with alkaline shampoo. If you spend a long time on your head after publishing, I suggest that you wait a little longer for the root part, otherwise there may still be color difference. That's about 20 minutes.

Note: To do a good job of protective measures, it is difficult to wash off the hair dyeing on your hands, it is best to wear an old clothes when dyeing your hair, bring plastic gloves, and apply the hair dye agent on the comb, and then evenly apply it to the hair, it is best to carefully take protective measures in advance, it is best to do ** test first, see if you are still allergic, or don't dye the scalp, you can also look at the instructions with a toothbrush.

And dye your own hair, if it's the first time!! You should apply less ointment behind your ears, and see if you have allergies after 24 hours, and make sure that your scalp is not broken or open!! Otherwise, the consequences are unimaginable, the light ones will be red, itchy, severe, some will be open, and the heavy ones will be lead poisoning.

By the way, it is recommended to use some amino acids after dyeing, which can protect the hair from damage and remove the chemicals in the hair!! It's good, hehe!!

Well, I hope it helps!! Hehe.

After washing your hair, wipe it with a towel slightly, then use the earmuffs for hair dyeing to cover the ears, you can also use a plastic bag without earmuffs, and then evenly spread the hair dye with a brush and comb, wrap the hair with plastic wrap after applying, and wash and dry it for about 10-15 minutes!

Hair dye usage.

1. Mix hydrogen peroxide and bleach together according to the instructions.

2. Divide the hair into many parts and apply it to your hair with a dye brush, starting at the top of the hair.

3. Arbitrarily divide the lower half of the hair into many parts, and apply the hair strands with your hands dipped in hair dye, so that it will be more even.

。。。There should be instructions on the package.

You don't need to wash your hair, it's normal, of course, wash your hair is the same, don't do it deliberately, but you must ensure the quality of your own hair dye, if you bring your own hair dye to the barber shop to do it, the barber shop does not guarantee the effect, if you are not satisfied with the color that comes out, they will say that it is a problem with your dye paste (it is likely to be this problem).

If you want to dye your hair, it is best not to wash it for two days、、、 no, because = its pigment particles are still stabilized, and it is best to wash it 、、、 after 2 days

Take products to the barber shop to dye your hair to pay attention to:

1. Ask the technician to disassemble it in person to ensure that the product you are using is the product you bring to avoid being dropped;

2. Determine the effect you want with the technician, and the color of the same dyeing paste will be slightly different from the technician's operation method;

3. If you bring a dye paste that is not used in the salon and is used at home, you must know the operation method and supervise the technician to use it, because they have not used the dye paste, and the wrong method will also cause hair dyeing failure;

4. Whether to wash your hair before dyeing, depending on your personal situation, if it is not oily hair, it is best to wash your hair the day before, because the scalp will secrete oil to protect the scalp, if oily hair, the hair will be oily the next day, you need to wash before dyeing to avoid oily hair can not be colored, or uneven coloring;

5. It is best to wash and care normally after two days of hair dyeing.

6. It is best not to believe the technician's diagnosis of hair, and to buy the products they recommend, you must have your own ability to discriminate.

Save the 300 dollars in the barbershop and see how to dye your own black hair and what to pay attention to when dyeing your hair.

Dyes for dyeing clothes are generally not available in supermarkets, but they can be purchased online or at chemical stores.

Dyeing method: 1) First, the fabrics that need to be dyed, including cotton products, silk products, and hemp products, are washed, fully shrunk, dried, and torn or opened according to the required specifications;

2) Preparation of dyeing water: make different colors of colored water according to the design requirements;

3) Folding: Fold the torn or open fabric according to the desired pattern and fold it into several layers;

4) Tie-dyeing: tie-dyeing for large flower-shaped patterns in fabrics;

5) Fixture sandwiching: For the small flower-shaped pattern of the fabric, take out the dyed fabric from the dyeing container to cool, remove the fixture and tie the thread, wash it with soapy water, and rinse it with water;

6) Color fixing: After piercing, sandwiching and dyeing, the fabric is fixed with a fixing agent, and the dyed fabric is washed, dried, ironed and flattened after color fixing, and the finished product is packaged.

According to the nature of the fiber of the dyed clothing, the appropriate dye is selected

1. Cotton and linen clothing: direct dyes, reactive dyes (because the molecular structure of cotton contains many hydrophilic hydroxyl groups, it is easy to absorb moisture and expand, can react with reactive groups, and is more alkali-resistant, so direct, reductive, vulcanized, ice dyes and reactive dyes can be selected).

2. Silk and wool clothing: acid dyes, reactive dyes.

3. Polyester: Disperse dyes should be selected for dyeing. (Because polyester is highly hydrophobic and not alkali-resistant at high temperatures, the above dyes are generally not suitable for use).

4. Chemical fiber: can not be dyed! (Because chemical fiber dyeing requires high temperature and high pressure conditions, and it is difficult for ordinary families to meet this condition).

Supermarkets don't usually sell dyes to dye clothes, but dyes can be purchased online.

However, there are a few things to keep in mind when buying dyes:

First, it is necessary to choose the appropriate dye according to the fiber nature of the dyed clothing (not one dye can dye all kinds of clothes).

Cotton and linen clothing: direct dyes, reactive dyes (because the molecular structure of cotton contains many hydrophilic hydroxyl groups, easy to absorb moisture and puff, can react with reactive groups, and is more alkali-resistant, so direct, reductive, vulcanized, ice dyes and reactive dyes can be selected).

Silk and wool clothing: acid dyes, reactive dyes.

Polyester: Disperse dyes should be chosen instead. (Because polyester is highly hydrophobic and not alkali-resistant at high temperatures, the above dyes are generally not suitable for use).

Chemical fiber: can't be dyed! (Because chemical fiber dyeing requires high temperature and high pressure conditions, and it is difficult for ordinary families to meet this condition).）

Second, if it is not a solid color of clothing, the choice of dye should also consider the splicing of colors.

Since most clothes are not solid colors, when color matching is required, the selection of dyes should pay attention to their composition, solubility, color fastness, dyeing rate and other properties. Due to the different dyeing properties of various dyes, the dyeing effect is often affected by the difference in temperature, solubility, dyeing rate, etc. Therefore, when color-matching, it is necessary to choose dyes with similar properties, and the closer the better, which can be conducive to the control of process conditions and the stability of dyeing quality.

3. In addition, the dyefastness of the dye should be considered.

Because the dyefastness is one of the important quality indicators to measure the dyed finished product, the dyefastness that is easy to fade is low, and the dyefastness that is not easy to fade is high. In addition, the concentration of dyed dyes suitable for the garment should be compared with the specified color concentration.

Because it is one of the important quality indicators to measure the finished dyed product, the dyeing fastness that is easy to fade is low, and the dyeing fastness that is not easy to fade is high.

You have to see what kind of fabric the clothes are to dye the clothes first, and some fabric dyes are not the same **All are sold on the ** I had a pair of jeans before that was faded from cotton I bought it in the ** clothes colorful store and came back to dye the pants myself.

Dyeing clothes at home, depending on what material your clothes are, if the clothes are cotton, linen, denim, you can dye at home, supermarkets must not sell dyes, this place to sell chemical dyes. However, there will be no detailed instructions for use in places that sell chemicals.

But**There are sales on the Internet, I remember that there is a shop called Suction Dyeing Workshop that sells clothes and dyes, which has a lot of pictures to display, as well as manuals, so that I feel more convenient to use. You can search for it.

Supermarkets won't have it. It is usually available at chemical stores.
