This is probably the most important question surrounding Brik & Pearl.
Traditionally, lash lift systems rely on a single reducing agent. Brik & Pearl instead combines two different reducing pathways.
Ammonium Thioglycolate provides highly effective bond reduction and reshaping.
Cysteamine HCl works alongside it to support a more controlled modification of the disulfide bonds.
Rather than relying on a single chemical pathway for bond modification, the chemistry is layered.
This allows the technician greater flexibility while helping support the structural integrity of the hair throughout processing.
