preventing and correcting "hot roots."
Created on 2024.09.18
Today, let's discuss methods for preventing and correcting "hot roots."
First, we need to consider why "hot roots" occur. There are two main reasons:
- The root area is too light.
- There is insufficient pigment, leading to uneven color.
To solve this problem, we need to increase the pigment. There are two methods:
- Use dye and developer. The ratio is 100g of dye to 50g of developer. This increases the pigment and prevents "hot roots."
- Add 2-0. The ratio is 1% to 3%. When applying to the roots, add 1% to 3% of 2-0 to increase pigment content, reduce lifting ability, and effectively prevent "hot roots."
If "hot roots" have already occurred, here's how to correct them:
Since the hair has already been dyed once and contains artificial pigment, directly covering it may not work well. Therefore, choose a base color 1 level darker than the mid-lengths. For example, if the roots are a level 5, select a darker base color when correcting the roots.
I hope these methods are helpful to you!
