8 methods of healthy hair dyeing


Nowadays, more and more people like to dye their hair. So, how can we balance beauty and health? Guangzhou Youji Daily Chemical Co., Ltd., a hair dye processing manufacturer, gives the following eight tricks. 1. Scalp to shoulders and neck, apply Vaseline.

Professional hairdressers will apply professional isolation liquid on the scalp of customers before dyeing their hair to protect the scalp. If you dye your hair at home, you can apply a layer of petroleum jelly to the scalp, décolletage and neck skin, which can also achieve a barrier effect. 2. Do an allergy test before dyeing your hair.

Apply a small amount of hair dye behind the ears or on the inside of the elbow, and stick it with breathable tape for 24-48 hours. If the skin is red, swollen and has a burning sensation during the test, it means that you are allergic to this hair dye and should be avoided; if there is no reaction, it means it is safe. 3. Do not wash your hair the day before dyeing your hair.

This keeps the oil on the scalp and protects it. 4. Avoid dyeing hair with shampoo. During the hair coloring process, in order to avoid a large amount of hair dye on the scalp, do not use the "washing" method of hair coloring.

5. If an allergic reaction occurs, seek medical attention immediately. Always pay attention to the condition of your scalp after dyeing your hair. If you experience an allergic reaction such as itching or swelling, seek medical attention immediately.

If neglected, it is easy to cause hair follicle necrosis. 6. The interval between two hair dyeings should be at least 3 months. In order to avoid excessive stimulation and damage to the scalp and hair follicles, the interval between two hair dyeings must be more than 3 months.

Frequent hair dyeing is easy to damage the hair quality and make the hair dyeing effect worse and worse. 7. Good quality hair and long-lasting hair color. The way to maintain long-lasting hair color is to avoid hair damage, such as using hair care products, shampoo temperature is not too hot, hair dryer temperature is not too hot, or through a balanced diet, adequate sleep, can keep hair healthy, smooth and soft to ensure The hair dye is fully retained and does not fade easily.

8. Find a professional to re-dye the hair roots. Human hair grows an average of 1 to 2 centimeters a month, so the hair roots need to be dyed frequently. Because the hair root is close to the scalp, it is recommended that a professional hairdresser try to handle it as much as possible.
