TLDR Thioglycolate lotions are the most popular method for permanent waving and hair straightening.

The document reviewed the evolution of permanent waving and hair straightening techniques, highlighting the significant shift in the 1940s with the introduction of thioglycolate waving lotions, which allowed for room temperature processing and reduced time and danger compared to earlier methods using alkali and heat.
