Eight ways to dye your hair healthily

Nowadays, more and more people like to dye their hair. So, how can you strike a balance between beauty and health? An old Chinese doctor teaches you 8 methods of healthy hair dyeing.

1. Apply Vaseline from scalp to neck

Professional hairdressers will apply professional isolation liquid to the customer's scalp before dyeing the hair to protect the scalp. If you dye your hair at home, you can apply a layer of Vaseline on your scalp and skin on your shoulders and neck to achieve an isolation effect.

2. Do an allergy test before dyeing your hair

Apply a small amount of hair dye behind the ear or inside the elbow, and stick it with breathable tape for 24 to 48 hours. If the skin becomes red, swollen, or has a burning sensation during the test, it means you are allergic to the hair dye and should avoid using it. If there is no reaction, it means it is safe.

3. Don’t wash your hair before dyeing it

It is best not to wash your hair one day before dyeing your hair, so that the oil on the scalp can be retained and the scalp can be protected.

4. Avoid shampooing and dyeing your hair

During the hair dyeing process, in order to avoid a large amount of hair dye on the scalp, never dye your hair by "washing your hair".

5. If you have allergies, seek medical attention immediately

After dyeing your hair, you must always pay attention to the condition of your scalp. If you have allergic reactions such as itching or swelling, seek medical attention immediately. If left untreated, it can easily cause hair follicle necrosis.

6. There should be at least 3 months between two hair dyeings

To avoid excessive stimulation and damage to the scalp and hair follicles, there should be an interval of more than 3 months between two hair dyeing sessions. Frequent hair dyeing can easily damage the hair quality and make the dyeing effect worse and worse.

7. Good hair quality leads to long-lasting hair color

The best way to make hair color last longer is to avoid damage to the hair, such as using hair care products, not using too hot water when shampooing, not using too hot a hair dryer, or working from the inside out through a balanced diet and adequate sleep, all of which can make hair dark, smooth and shiny, thereby ensuring that the hair dye is fully retained and does not easily fade.

8. Find a professional to dye your hair roots

On average, human hair grows 1-2 cm per month, so the roots of the hair need to be re-dyed frequently. Since the hair roots are close to the scalp, it is recommended to let a professional hairdresser do the re-dying.
