TLDR Hair straightening changes hair structure and can cause damage if done wrong, but improvements in the methods are expected to continue.
The document from 2015 discusses the methods of hair straightening, which involves altering the hair's cortex. Temporary straightening changes hydrogen bonds and salt linkages, while permanent straightening modifies covalent bonds using chemicals like ammonium thioglycolate, sulfites, and hydroxides. The treatments are popular for their ability to provide style versatility and manageability, but there is a risk of overprocessing if done incorrectly. The document suggests that future improvements in hair straightening technology will continue to be made, but the use of heat and chemicals will likely persist. It emphasizes the importance of understanding the benefits, drawbacks, and correct application of each method to minimize potential damage, tailored to individual style preferences and hair characteristics.
