research Permanent Hair Styles (“Perms”)
Permanent hairstyles, or "perms," involve chemical treatments that restructure hair to create lasting curls or waves by altering disulfide bonds in hair keratin. While perms provide durable cosmetic effects, they can damage hair shaft integrity, cause scalp irritation, and pose systemic health risks. Issues such as irritant contact dermatitis and acquired trichorrhexis nodosa are highlighted in case studies. To minimize harm, it is crucial to assess clients properly, choose the appropriate perm type, follow safe application techniques, and ensure post-treatment care. This chapter offers guidance on the chemical principles, clinical complications, and practical recommendations for safe perm practices.
research Targeted keratin repair: A plant‐based approach to hair strength and surface restoration
The study investigates the effectiveness of a plant-derived amino acid complex from Avena strigosa seed extract in repairing chemically damaged hair. The treatment significantly improved hair properties, as evidenced by scanning electron microscopy, glossmetry, and tensile testing. Results showed a 23% decrease in surface area porosity, a 105% increase in gloss after five washes, and up to a 30% improvement in tensile strength. Molecular assays confirmed the complex's interaction with keratin, reducing free sulfhydryl groups by 9.2% and stabilizing disulphide bonds. An in vivo study with 20 participants demonstrated enhanced shine and smoothness compared to a placebo. The A. strigosa complex effectively reinforces keratin intra-bonding, offering a promising solution for restoring hair strength and surface quality.
