TLDR Cosmetic procedures can harm hair, but damage can be minimized with knowledge and care; however, once hair is damaged, it cannot be reliably repaired.
The document from 2017 provides a comprehensive overview of hair anatomy, the impact of cosmetic procedures on hair health, and methods for assessing hair damage. It explains that hair is composed of the medulla, cortex, and cuticle, with keratin as the primary protein, and that hair characteristics vary by ethnicity. Cosmetic procedures such as thermal styling and chemical treatments with thiols, bisulfite, hydroxides, and formaldehydes can alter hair texture but also cause damage. The document highlights the importance of intervals between treatments, proper neutralization, and moisturizing treatments to minimize damage. It also discusses hair dyes and the types of hair damage that can result from cosmetic treatments. Various assessment techniques, including Protein Loss Assessment and Scanning Electronic Microscopy, are outlined for evaluating hair health. The conclusion emphasizes that while cosmetic procedures can damage hair fibers, understanding hair structure and using preventative measures can help maintain hair health, but once damaged, there are no reliable means of repair.
