What is the role of glycerin in permanent waving lotion?

Glycerin plays an important role in permanent waving lotion mainly due to its moisturizing properties. Its ability to retain moisture contributes to the overall health of the hair during the chemical process. When used in permanent waving solutions, glycerin helps to lower the pH, which aids in creating a more balanced and lower alkalinity environment that is less damaging to the hair. This is essential, as maintaining appropriate pH levels can help in achieving effective hair curl formation while minimizing cuticle damage.

The other aspects of glycerin, such as its hydrating qualities, help to counteract the drying effects that can occur from the wave-forming chemicals. As a humectant, glycerin attracts water, ensuring that the hair maintains some level of hydration throughout the chemical process. This ultimately leads to healthier results and more resilient curls compared to formulas lacking such moisturizing agents.
