Eight bags of worry-free hair dye usually contain eight small packaging bags, each of which is: hair dye, oxidant and conditioner. The usage method is as follows:

1, shampoo and dry your hair.

2. Fully mix the hair dye and oxidant, shake it evenly, immediately open it, quickly apply it to the hair, fully massage the hair, and ensure that the hair is dyed evenly.

3. Wait for 30-40 minutes (the time depends on the required dyeing effect), during which you can wear a shower cap or wrap a towel to keep warm.

4. Rinse your hair thoroughly with warm water until the water is clear and colorless.

5. Take out the conditioner, apply it to the hair, let it stand for 2-3 minutes, and then rinse it with clear water.
