“Hair dye remover”, a term that was very famous in the cosmetic industry about a few years ago. Though permanent hair dye is applied to have a stable color that will be difficult to remove, sometimes you want to remove the hair color for several reasons. In this article, I will be providing you with 3 simple techniques to remove permanent hair color with hair dye removers at home.
The 3 main hair dye removers
1. Vegetable oil
The first method of removal can be using hot vegetable oil.
- First vegetable oil is applied to the hair.
- Then the strands of hair are passed through a comb and then rubbed with a towel.
- Vegetable extract dyes and lead dyes can be easily removed by this technique.
- Silver color and copper color are difficult to remove by this method.
- Oxidation dyes cannot be removed by this method.
2. Turkey Red Oil
Turkey Red Oil can be used to remove dyes and is also advantageous as some other additives can also be incorporated to help in the removal of the hair color.
3. Chemical reagents
Chemical reagents can also be used as artificial dyes.
- Metallic dyes are not removed by chemical reagents as they cause a violent production of heat which will damage hair and scalp.
- Oxidation dyes can be removed by treating with reducing agents such as sodium hydrosulfite, sodium formaldehyde sulphoxylate, sodium thiosulphate, sodium dithionate solutions.
- Hydrogen peroxide solutions in 5-6% strength can be useful for lighter shades of oxidation dyes, but not for dark shades.
- Most of them are used in acidic solutions.
- Sodium Formaldehyde sulphoxylate is used as a weakly ammoniacal solution.

Quality tests for hair dye remover
As hair colorants can cause sensitization of skin or can produce toxic effects, it is imperative to do tests for this apart from normal quality test for ingredients and their quantity.
1. Sensitization Test
This can be done on the animal skin by applying dye stuff or the preparation and observing the effect on the skin. If necessary, histopathological study can be done of the related tissues or cells when applied.
2. Long term toxic effect
This is also necessary to evaluate the long-term effect. This can also be done on human beings.
