Regardless of the school's opinion, let's talk about dyeing your hair first, and then, it's up to you to choose whether it's good or not.
Benefits of dyeing hair
1, molded from the overall temperament
Generally speaking, we Asians are not tall. At this time, if the hair color is too heavy, it will make people feel heavy overall. A little layering on the hair, combined with highlights suitable for your temperament, can not only increase the lightness and texture of the hair, but also increase the sense of change from the perspective of modeling, so that the image will become lively.
2. Adjust emotionally
There is a subtle relationship between the color of hair and mood. Changing your hair color can also change your mood. Red gives people a feeling of enthusiasm, boldness, vitality and irritability; Yellow gives people a noble and brilliant feeling. If you are depressed and low-key recently, you can choose bright hair color; If you are impetuous and unstable recently, you might as well dye your hair deeper and thicker.
3, from the skin color and dress.
Dyeing your hair can make you more feminine and set off your complexion and dress. Different hair colors have different aesthetic feelings, and brown hair is soft, giving people an approachable intimacy. Dark hair is dignified and elegant, which can emphasize the unique oriental beauty. When the temperament, face and dress style are oriental, you can always be black, but there are too few guests who meet these conditions. Fan Bingbing and Cecilia Cheung, for example, are typical oriental beauties, and most people still need colors to set them off. People with fair skin should choose warm colors to dye their hair. And if you want to be more feminine, you can try light linen.
4, from the perspective of cooperation with the face.
Well-designed color processing can make the face more charming. Dyeing a handful of forehead hair with highlights, or just brushing the surface to do key dyeing, will attract others' attention, thus emphasizing the more beautiful part of the face. Or just emphasize the hair around the face, frame the face like a book frame, and highlight the hairstyle and the outline of the face.
5, from the creation of taste
Proper highlighting or gradient will make you have a strong sense of fashion and reveal your unique taste, which can also give your hair a sense of rhythm. If the basic hair color is dark, you can choose wine red, purple red and brown red similar to black. If the basic hair color is light, the contrast color or similar color will make the effect very significant. For example, highlight or gradient purple or smoky gray on linen background.
Harm of hair dyeing
1, skin allergy
The main component of hair dye is p-phenylenediamine, which is a strong allergen, and people with allergies will have allergic reactions. At present, in Germany, France and other countries, p-phenylenediamine is forbidden to be used in hair dyeing, but it is still used in China.
2, aggravate hair loss
After dyeing hair, many people will have hair loss aggravated, mainly because chemicals such as p-phenylenediamine will penetrate into hair skin, causing peroxidation, leading to dry skin and hair loss.
3. Damage to liver and kidney
Nowadays, many unscrupulous merchants in the market will add heavy metal components such as mercury, arsenic and lead in order to make the dyeing effect of products better. Dye your hair in private. If these chemicals come into contact with the human body, they will bring harm to people's health, even seriously damage the liver and kidney and affect their functions.
4. Carcinogenesis
A study by Yale University in the United States shows that more than 1/3 of women who start dyeing their hair from 1980 will develop lymphoma. A study by the American Cancer Society shows that women who dye their hair have more than three times the risk of leukemia than women who don't. At present, there are many international studies on the carcinogenicity of hair dyeing, but whether hair dyeing is carcinogenic is still controversial. However, to prevent cancer, it's best to get less.
