Preparation tools/materials: bib, earmuffs, hair cream, gloves, hair comb, conditioner and shampoo oil.
1, prepare hair dyeing tools.
Dyeing your own hair is not just about using hair cream. In the process of dyeing your hair, we also need small bowls, combs, hair care essential oils, disposable gloves, big hair clips and hair dryers to help you dye and color better.
2. Don't wash your hair two days before dyeing your hair.
3. Do a skin test before dyeing your hair?
Hair dye cream contains certain chemical components, so it is inevitable that some hair dye cream will fall on the scalp during hair dyeing. Therefore, it is best to do an allergy test on the skin first to prevent skin allergy. The specific method is to apply a small amount of hair dye cream directly behind the neck or ears to observe whether the skin has abnormal reaction. If there is no discomfort, hair dyeing will officially start. ?
Step 4 mix hair dye cream
Usually, there are two kinds of dyes in hair cream, and the dosage is 1: 1. After the two dyes are mixed together and stirred evenly, 2-4 drops of hair care essential oil can be dropped. Hair care essential oil can moisturize and supplement the nutrition of hair. When used together with hair dye cream, it can reduce the damage caused by hair dye cream.
5. dye your hair?
Wear disposable gloves after the hair dye paste is adjusted to prevent the hair dye paste from falling on your hands. Generally, we should dye from the hair roots first. Excess hair can be clamped with a big hairpin first, and then the hair dye cream can be applied with a comb. Be careful not to rub it directly on the scalp. Keep a distance of 3 mm from the scalp. After applying the hair dye cream evenly from top to bottom with a comb, observe whether all the hair is applied, and then make up the painting where it is not applied, so as to ensure that each hair has a good color. ?
6. Wait?
After all smearing, wait 15-20 minutes, and then rinse with clean water. Please note that the maximum waiting time should not exceed 30 minutes. Thick hair is more difficult to absorb hair dye cream than fine hair, so the waiting time can be slightly extended. In addition, in the process of waiting, you can use a hair dryer to blow the hair hot, which can help the hair scales open faster, thus speeding up the coloring speed.
Step 7 clean
Wear gloves when cleaning hair dye paste. Wash with clear water first, and be careful that the water temperature is not too hot, otherwise it will burn the scalp and affect the hair color. It is best to rinse with warm water, and do not use shampoo after rinsing, otherwise it will fade easily. However, the use of conditioner is inevitable. Conditioner can better maintain hair and make it smooth, especially freshly dyed hair. The conditioner needs more maintenance after use.
Extended data
With the continuous improvement of the quality of life, people pay more and more attention to appearance. Walking in the streets, it is not difficult to find that dyeing hair, especially colored hair, has become a consumption fashion. According to the requirements of consumers, we can dye it in a variety of colors: grape red, brilliant purple, wine red and so on. The purpose of dyeing hair is for beauty, but do you know how much harm there is behind this beauty?
Injury type
First, oxidant is an important part of hair dye, which is very destructive to hair keratin and easy to cause damage to hair. Regular use will make hair dull, fragile, split and easy to fall off.
Secondly, most permanent hair dyes use aniline dye intermediates, which are highly irritating and toxic in cosmetic raw materials. No wonder some people have allergies and even dizziness and nausea when dyeing their hair.
Thirdly, hair dye consists of two components. When in use, it is mixed first and then applied to the hair. I don't know that a chemical reaction took place at the moment of mixing, which produced a high concentration of harmful gas-dioxin. Dioxin is a strong carcinogen recognized by WHO. It enters the body through the respiratory tract and stays in the muscle for a long time, which is difficult to decompose and interferes with human endocrine, estrogen and thyroid hormone. Long-term exposure will lead to genetic variation and deformity of human body and induce diseases such as cancer. Therefore, it is scientific to be pregnant and pregnant women not to dye their hair.
Prevention and rehabilitation
If there is, it is necessary to prevent it. How can we stay away from these hazards to the maximum extent?
1, consumers should try to choose hair salons with good ventilation;
Step 2 choose ordinary hair dye
