Different hair types have varying levels of thickness, all of which are important factors to consider when deciding to dye your hair. Your hair thickness can either be low (fine hair), medium, or high.

If your hair thickness is high or medium, then hair dye can stay in your hair for as long as is on the instructions and even a little while longer before the chemicals begin to affect it negatively.

However, the case is different for fine hair, it is much lighter than the other hair types and needs to be paid more attention to especially when being subjected to a chemical hair treatment or process such as hair dyeing.

For fine hair the risk of being damaged is higher when you leave the hair dye in for longer than usual, sometimes you might even have to rinse out the dye before the time indicated in the instructions when you notice that the color has developed faster than you would have expected, this saves your hair from becoming thinner.

2. Has Negative Effect On High Porosity Hair

 If you didn’t know earlier, you should know now that your hair porosity also plays a vital role in the hair dye process. If your hair has a high porosity, it will absorb more of the hair dye, and faster than others, it continues to absorb the hair dye until it is rinsed out at the end of the process.

This is a huge disadvantage because hair dye contains chemicals that your hair should not be exposed to too much. By absorbing hair dye faster, hair with high porosity is likely to suffer from more hair damage when the hair dye is left in for longer than necessary.

3. Exposes Hair To Toxic Chemicals

Hair dyes need the presence of chemical Ingredients for the hair color to develop. This means that as long as you have decided to dye your hair, you have accepted the risk of hair damage as a result of toxic chemicals when you leave the hair dye in for longer than you have been instructed to.

The toxic chemicals present in hair dye include; ammonia, p-Phenylenediamine, resorcinol, lead acetate, and hydrogen peroxide.
