| a is a perm wrap in which one end paper os placed under and another is places over the stand of the hair beigh wrapped | double flat wrap |
| which types of rod are usually about 12 inches( 30.5 centimeters) long with a uniform diameter along the entire length of the rod | softe bender rods |
| thiogycolic acid | is a common reducing agent |
| the is the innermost layer of the hair | medulla |
| the parting and bases radiate throughout the panels to follow the curvature of the head in which type of wrap | curvature permanent wrap |
| the chemical bond that join amino acid together are called | peptide bond |
| a is a type of perm wrap in which the hair is wrapped at an angle other than perpendicular to the length of the rod | spiral perm wrap |
| which of the following is a methodd of hair straightning that cobine the use of a thio relaxer with flat ironing | Japanese thermal straightening |
| which type of relaxer requires the the application of a protective base cream to the entire prior to the application of the relaxer | base relaxer |
| the middle layer of the hair | cortex |
| which of these term refers to the angle at which the rod is positioned on the head: horizontally, vertically, or diagonally | base direction |
| is a type of wrap that uses one end paper folded in half over ends like an envelope | bookend wrap |
| is a wrapping pattern in which all the rods within a panel move on the same direction and are positioned on equal- sized bases | basic permanent wrap |
| which of these are usually classified as a lye- base relaxer | sodium hydroxide relaxer |
| which rod are equal in diameter along their entire length of curling area | straight rods |
| which if these tern refers to the thickness or thinness of a liquid | viscosity |
| is the tough exterior layer of the hair | cuticle |
| which of these terms refers to the position of the rod in relation to its base section | base placement |
| is a type of wrap in which the hair is wrapped on one rod from the scalp to midway down the hair shaft, and another rod is used to wrap the remaining hair strand in the same direction | piggyback wrap |
| which of these stops the action of the waving solution and rebuild the hair intio a new curly form | thio neutralization |
| long chain of amino acid joined together by peptide bond are known as | polypeptide chain |
| the process by which hydroxide relaxers permanently straighten hair is called | lathionization |
| hydrogen bond can be nroken by | either water or heat |
| the reducing agent used in permanent waving solution is commonly referred to as | thio |
| manufacturers add an alkalizing agent to waving solution because the acid in the solution | does not swell the hair or penetrate into the cortex |
| a ph of 7.0 is than the ph of hair | 100 times more alkaline |
| most of the acid waves found in today salon have a ph between | 7.8 and 8.2 |
| which of the following is not considered a man component of an exothermic wave | concentrator |
| an endothermic chemical reaction is one that absorbs from its surrounding | heat |
| which type of perm is recommended for extremely porous hair | true acid wave |
| what is the most common neutralizer | hydrogen peroxide |
| when rinsing the hair after the recommended processing time has elapsed, it is recommended that you | smell the hair to determine if it still smells like perming solution |
| mid-strength relaxers are formulated for | fine, color-treated, or damaged hair |
