10 tips for women who love hair dyeing to avoid "poisoning"

2. Permanent hair dye should be used less. Consumers who use permanent black hair dye should consider switching to a lighter color because the darker the color, the more toxic it is. Generally speaking, hair dyes that fade when you wash your hair three or four days after dyeing are temporary hair dyes, hair dyes that fade one to two weeks after dyeing are semi-permanent hair dyes, and hair dyes that basically do not fade for more than two weeks after dyeing are permanent hair dyes. The first two are less toxic, while the latter is more toxic.

3. Do not dye your hair with different hair dyes at the same time. Hair dyes may react chemically to produce toxic substances.

4. It is best to keep hair dye close to 1 cm away from the scalp.

5. People with boils, skin ulcers and those who are allergic to hair dye should not dye their hair. If you insist on dyeing your hair, be sure to do an allergy test. Apply the hair dye on the skin behind the ear. If there is no abnormal reaction within two days, you can dye your hair. People with high blood pressure, heart disease, or those who are pregnant or giving birth should not dye their hair.

6. Before dyeing your hair, apply some Vaseline on your scalp. If your hair gets stained with chemicals, it will be easy to wash off.

7. Please remind the hair dye technician not to use metal utensils when mixing the liquid.

8. After dyeing your hair, wash it several times to avoid leaving any dye residue on your hair. When washing your hair, be careful not to scratch your scalp with your fingers to avoid poisoning.

9. It is best to purchase qualified products with low toxicity that have passed national safety evaluations.

10. Have regular physical examinations.
