| aka end bonds. connect amino acids. | peptide bonds |
| protein building blocks of hair that link together to for tiny protein fibers. | amino acids |
| spiraling chain of amino acids. | polypeptide chain |
| aka cross bonds. connect polypeptide chains. (Strength & elasticity) | side bonds |
| broken by water or heat. restored by cool or dry. | hydrogen bonds |
| broken by pH. restored by pH. | salt bonds |
| broken by chemical solution. restored by neutralizing solution. | disulfide bonds |
| illness caused by overexposure to certain products or ingredients. | occupational disease |
| 2 or more types of matter blended together but not chemically changed. | physical mixture |
| can mix | miscible |
| can not mix | Immiscible |
| curly/WAVY hair into straight hair | chemical relaxing |
| removing 1 sulfur atom & replacing it with a disulfide bond | Lanthionization |
| solution with an acid pH to restore the natural pH of the hair after a hydroxide relaxer | normalizing lotion |
| removes remaining chemical left in the hair | neutralizing shampoo |
| aka rebonding. chemically restoring disulfide bonds to harden into a new shape | neutralizing |
| aka acid/alkali neutralization reaction. neutralizes remaining alkaline residue from hydroxide relaxer & restores pH to hair & scalp | hydroxide neutralization |
| how thick or thin a liquid is | viscosity |
| relaxer with high alkaline | hydroxide relaxer |
| strong alkaline ingredient used in a chemical relaxer | sodium hydroxide (lye) |
| very strong alkaline ingredient used in a chemical relaxer. (no mix/no lye) | potassium/lithium hydroxide |
| requires the mixing of 2 products. (no lye) sensitive skin | guanidine hydroxide |
| requires a base cream | base relaxer |
| does not require a base cream. aka no lye relaxer | no base relaxer |
| aka thio relaxer. w ammonia. no lye. for soft curl reformation | thioglycolate relaxer |
| combination of ammonia and thioglycolic acid that creates a reducing agent used in a perm & relaxer | ammonium thioglycolate (ATG) |
| mild, alternative relaxer containing a low pH compatible w thio relaxers | ammonium bisulfide relaxer |
| organic, colorless, flammable & pungent gas present in the air, foods,and beauty products | formaldehyde |
| result from thr oxidation of primary alcohols | aldehyde |
| products without the use of formaldehyde but could omit a gas upon use | formaldehyde free |
| straight hair into curly/WAVY hair | permanent waving |
| chemical solution that stops the waving process of a perm wave. rebuilds the bonds into a new form | neutralizer |
| process of stopping a permanent wave & reforming the hair into its new shape | thio neutralization |
| aka cold wave. without heat. main ingredient is thioglycolic acid | alkaline wave |
| main ingredient in true acid waves | |
| glyceryl monothioglycolate (GMTG) | |
| heat. pH 4.5 - 7. main ingredient GMTG. process slower than alkaline waves. | true acid waves |
| without heat. pH 7-8.2 produce a firmer curl. process quicker than true acid waves | acid balance waves |
| heat. hood dry. heat processor | endothermic wave |
| self-heating | exothermic wave |
| using ingredients other than ammonia to reduce the odor | ammonia free waves |
| aka flexible rods. foam covered easily bent. | Bender rods |
| pliable foam rods that allow the hair to be chemically altred w as often result | sponge rods |
| wrapping the hair from ends to scalp in overlapping concentric layers | croquignole wrap |
| wrapping the hair at an angle creating a coiling effect | spiral wrap |
| the position of the perm rod within the section/parting | base direction |
| subsections located within a larger panel section . the hair is divided into smaller subsections that holds one perm rod each | base section |
| aka base placement. the position of the tooling relation to its base section and is determined by the angle twice the hair is wrapped | base control |
| aka straight wrap or 9 block wrap. | basic perm wrap |
| consist of parting that follow the shape of your guest head | curvature perm wrap |
| staggered pattern of subsections | bricklay perm wrap |
| zigzag partings | weave perm wrap |
| aka double rod. hair longer than 10 -12 in is wrapped on the rod from midshaft to scalp and remaining hair is wrapped around a second rod | piggyback perm wrap |
| chemical textures service that restructures overly curly hair into loose curls or waves | soft curl reformation |
| hair to absorb any liquid | porosity |
| cleaning tools with warm, soapy water and submerging in an epa-registered disinfectant | disinfecting |
| sets the standards for what info the sds contains | globally harmonized system (ghs) |
| mandates the every chemical located within a business has a sds available | occupational safety & health administration (Osha) |
| cleaning tools with warm soapy water to remove debris and then placing them in a high pressure steam unit | sterilization |
| packaged together as a bundle . 9 | protofibrils |
| examples of miscible | alcohol and water |
| examples of immiscible | facial cream, oil,shampoo & conditioner |
| the complete process | thio neutralization |
| causes dry, damaged hair with increased breakage | over processed |
| causes insufficient curl pattern due to timing or inadequate saturation | under processed |
| breakdown of disulfide bonds | reduction |
| neutralizing remaining lotion in the hair after processing and rinsing | oxidation |
| the application of a chemical agent to the hair, followed by a series of steps necessary to straighten the hair | chemical straightening process |
| chemically restores the disulfide bonds to their newly hardened shape | rebonding |
| best used on color treated, fine textured hair with severe porosity | mild relaxer |
| used on medium extrude hair with normal porosity | regular relaxer |
| used on coarse textured hair with resistant porosity | super relaxer |
| 2 forms of hydroxide relaxer | sodium hydroxide potassium/lithium hydroxide |
| waves that require no heat and have a ph above 7.1 | alkaline |
| main ingredient in an alkaline wave | thioglycolic acid |
| disulfide bonds connect two sulfur atoms located in the amino acid | cysteine |
| aka cold wave | alkaline waves |
