| Question | Answer |
|---|---|
| Permanent waving is..? | a two-step process whereby the hair undergoes a physical change caused by wrapping the hair with perm rods, and then the hair undergoes a chemical change with the use of a perm waving solution and a neutralizer |
| A perm wrap is..? | a wet set on perm rods |
| In permanent waving the size of the curl is determined by..? | the size of the rod |
| Types of rods inlcude: | concave, straight, soft bender and loop |
| The strength of any permanent wave is based on..? | the concentration of its reducing agent |
| In permanent waving the neutralization.. | stops the action of the waving solution and rebuilds hair into its new curly form |
| Types of perm wraps include: | basic, curvature, bricklay, piggyback and weave |
| What is a partial perm? | a perm for a client that would like a perm but does not wish the entire head of hair to be curled |
| Partial perms also allow..? | you to give a perm when some of the hair is too short to roll on rods |
| In a curvature perm wrap.. | partings and bases radiate throughout the panels to follow the curvature of the head |
| In a bricklay perm wrap.. | base sections are offset from each other row by row to prevent noticeable splits and to blend the flow of the hair |
| In a weave technique wrap.. | zigzag partings are used to divde base areas for blending between perm rods with opposite base dirctions and create a smooth transition from the rolled areas to unrolled areas of a perm |
| Endothermic waves.. | are activated by an outside heat source |
| Exothermic waves.. | create an exothermic chemical reaction that heats up the waving solution and speeds up processing |
| The use of sulfates, sulfites, and bisulfites presents an alternative to ATG known as.. | low pH wave |
| Perms that use an ingredient that does not evaportate as readily as ammonia are..? | ammonia-free waves |
| These waves use an ingredient other than ATG as the primary reducing agent. | thio-free waves |
| Permanent waves that have a 7.0 (neutral) pH | acid-balanced waves |
| Waves that have a pH between 4.5 and 7.0 and require heat to process and process slower than alkaline waves.. | true acid waves |
| Alkaline permanent waving solutions.. | soften and swell the hair |
| End papers, also known as end wraps are.. | papers used to control the ends of the hair when wrapping/winding the hair onto a perm rod |
| What are polypeptide chains? | Long chains of amino acids joined together by peptide bonds |
| Viscosity is.. | the measurement of thickness or thinness of a liquid that affects how a fluid flows |
| Alkaline Waves.. | pH 9.0-9.6 and use ATG as a reducing agent, process at room temperature no extra heat needed |
| GMTG | main active ingredient in true acid and acid balanced waving lotion |
