Florida cosmetology state board (clinical) Exam And Accurate Answer

Florida cosmetology state board (clinical) Exam And Accurate Answer thio-free waves - Answer -Perm that uses an ingredient other than ATG as the primary reducing agent, such as cysteamine or mercaptamine. Hydrogen bonds - Answer -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 - Answer -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: - Answer -Aminomethylpropanol (AMP) Monoethanolamine (MEA) ammonia-free waves - Answer -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 - Answer -Main active ingredient in acid balanced waving lotions. Primary reducing agent in most acid waves. Low pH Sodium hydroxide relaxers are also known as? - Answer -Lye relaxers acid-balanced waves - Answer -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 - Answer -Disulfide, salt, and hydrogen bonds that cross-link polypeptide chains together. keratin proteins - Answer -Long, coiled polypeptide chains. Silicones - Answer -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.... - Answer -The bonds cannot be reformed with any other chemical treatment True acid waves - Answer --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 - Answer -2.5-4.5 Acid waves - Answer -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 - Answer -The process by which a hydroxide relaxer removes one atom of sulfur from a disulfide bond. Volatile organic compounds - Answer -Compounds containing carbon that evaporate easily. ex.) SD alcohol (ethyl) in hairspray Used in nail polish, base & top coat & polish removers Ammonia - Answer -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 - Answer -Carbon, nitrogen, hydrogen, sulfur, oxegyn What is waving lotion? - Answer -Hair gel that keeps it in place during finger waving process alkaline solution - Answer -A solution that has a pH above 7.0 (neutral) soften and swells the cuticle. ammonium thioglycolate (ATG) - Answer -Active ingredient or reducing agent in alkaline permanents. Alkaline waves - Answer -also known as cold waves; have a pH between 9.0 and 9.6, use ammonium thioglycolate (ATG) as the reducing agent, and process at room temperature without the addition of heat
