4 factors that affect the hair coloring process

Everyone has different hair. These individual differences could affect the hair coloring process. Here are 4 things you should take into account before you color your hair:

1. Type of hair

The end result of the hair coloring process varies based on the characteristics of the hair itself.

Thin, soft and easily-permed hair is easy to color, while thick, stiff hair that is difficult to perm is harder to color.

2. Temperature

If the temperature is high, the reaction speeds up, and coloring is easy.

If the temperature is low, the reaction slows down and makes coloring harder.


The effectiveness of the hair coloring process may vary depending on the temperature of the room in which it is done. Try to keep the room temperature between 20~30℃.

3. Amount of dye applied

For places that are hard to color, one should generally apply more solution.

The human head has different temperature zones. Naturally, this also affects the coloring process. Varying the amount of hair color solution applied for each area would help to avoid unevenness in the result. As gold and blond bleach solution accumulates easily in the root, this may result in unevenness as well. To counter this, apply the solution 1~2cm above the root of the hair.


4. Time

Hair that is easy to color will take the amount of time as stated, while hair that is difficult to color will take longer than the time stated.

The time required for the hair color to set depends on your hair type. Problems such as uneven coloring might arise if the actual time taken differs greatly from the time stated in the instructions..
