A new amino acid derivative, ATS, improves hair texture and moisture, making it easier to straighten curly hair.
research J. Cosmet. Sci., 59, 203-215 (May/June 2008) �Effects of permanent waving on changes of protein and physicomorphological properties in human head hair
Permanent waving damages hair protein and weakens hair, especially with repeated treatments using sodium thioglycolate.
research The toughening transition in hair keratin
The observed "toughening" in keratin was actually due to water evaporation, not a real change in keratin.
