The chemistry is designed to target the disulfide bonds that provide strength and rigidity to the keratin protein in hair. Understanding the Core Chemistry The primary action of a chemical depilatory is the disruption of the hair's structural integrity.
How Sodium Thioglycolate Works to Break Down Hair Structure
This high pH is necessary to activate the key ingredient, typically sodium thioglycolate or calcium thioglycolate, which serves as the hair-dissolving agent. Calcium thioglycolate, often found in newer creams and lotions, is generally considered less odorous and gentler on the skin, providing a more pleasant user experience while performing the same essential function.
Individuals with coarse or dark hair typically see the best results, as the high concentration of keratin provides a strong target for the chemical reaction. Rushing this process by wiping the product off too early will result in incomplete hair removal, as the disulfide bonds have not fully broken.
