Florida cosmetology state board (clinical) 100% verified

Florida cosmetology state board (clinical) 100% verified thio-free waves Perm that uses an ingredient other than ATG as the primary reducing agent, such as cysteamine or mercaptamine. Hydrogen bonds Very weak side bonds; that are the result of attraction between opposite electrical charges. Easily broken by water or heat. Reform as the hair dries or cools. Accounts for 1/3 of hairs total strength Salt bonds Weak physical side bonds (cross bonds) easily broken by change in pH; reform when pH balance is restored. Accounts for 1/3 of hairs total strength. Substitutes for ammonia in permanent waving solutions: Aminomethylpropanol (AMP) Monoethanolamine (MEA) ammonia-free waves Perms that use an ingredient that does not evaporate as readily as ammonia, so there is very little odor associated with their use. (AMP or MEA) Glycerol monothioglycolate Main active ingredient in acid balanced waving lotions. Primary reducing agent in most acid waves. Low pH Sodium hydroxide relaxers are also known as? Lye relaxers acid-balanced waves Permanent waves that have a 7.0 or neutral pH; because of their higher pH, they process at room temperature, do not require the added heat of a hair dryer, process more quickly, and produce firmer curls than true acid waves. Side bonds Disulfide, salt, and hydrogen bonds that cross-link polypeptide chains together. keratin proteins Long, coiled polypeptide chains. Silicones Special type of oil used in hair conditioners, water-resistant lubricants for the skin, and nail polish dryers. When a hydroxide relaxer breaks the disulfide bond converting them to lanthonine bonds.... The bonds cannot be reformed with any other chemical treatment True acid waves -Have a pH between 4.5-7.0 and require heat to process. -He process slower than alkaline waves -GMTG is the active ingredient pH level of Hydrogen Peroxide 2.5-4.5 Acid waves Glyceryl monothioglycolate is the main active ingredient in true acid and acid-balanced waving lotions. It has a low pH and is the primary reducing agent in most acid waves. Most acid waves also contain ATG, just like a cold wave. Although the low pH of acid waves may seem ideal, repeated exposure to GMTG is known to cause allergic sensitivity in both hairstylists and clients. Lanthonization The process by which a hydroxide relaxer removes one atom of sulfur from a disulfide bond. Volatile organic compounds Compounds containing carbon that evaporate easily. ex.) SD alcohol (ethyl) in hairspray Used in nail polish, base & top coat & polish removers Ammonia Colorless gas with pungent odor composed of hydrogen & nitrogen. Used to raise pH in hair products to allow solution to penetrate hair shaft. amino acids Carbon, nitrogen, hydrogen, sulfur, oxegyn
