Which chemical compound is the main ingredient in true acid waves?

The main ingredient in true acid waves is glyceryl monothioglycolate (GMTG). This compound is crucial in the formulation of true acid waves because it operates at a lower pH level compared to alkaline waves. This unique feature allows true acid waves to offer more control and gentleness during the curling process, leading to a more delicate and conditioned result on the hair. The lower acidity also means that true acid waves are less damaging to the hair than formulations with higher pH levels.

Glyceryl monothioglycolate works by breaking down the disulfide bonds in the hair, allowing it to be reshaped into curls. This makes it particularly suitable for more fragile, color-treated, or previously processed hair, as it helps to minimize the risk of damage while still achieving beautiful, long-lasting waves.
