Purchase note:

all shipped products do not have "no effect". Only the hair that can be colored and the operation method is incorrect. All materials in the factory will be tested for quality and tinctorial power tested with hair before filling, filling is carried out only after the test is passed, so there is no case that 1 to 2 boxes of goods in each batch are not colored.

If the reason for not coloring is analyzed, there will be the following situations:

1. When squeezing, only one side of the bottle mouth exports the paste, which will not be colored (it is normal if both holes squeeze the paste at the same time)

2. The internal damage of the bottle during the transportation of the product will not be colored After Mixed oxidation of agent 1 and agent 2 (No. 1 and agent 2 will not be colored After Mixed oxidation for more than 3 days)

3. Uneven application on personal operation or failure to follow the product instructions will also lead to coloring problems.

4. The hair of individual groups is particularly thick and hard, and the weather in the region is particularly cold, and the stay time is short, which will lead to no coloring.
