What are the most common types of chemical hair relaxers?

Ammonium
Sodium
Lye
No-lye

The correct answer is: Ammonium

The most common types of chemical hair relaxers are actually B and D sodium and no-lye. While A and C (ammonium and lye) have also been used in the past, they are now considered less common and less popular options due to their harsh chemicals and potential to cause hair damage. Therefore, option A is incorrect as it is not one of the most common types of chemical hair relaxers.
