|
|
Term
|
Definition
| Perms that use an ingredient that does not evaporate as readily as ammonia, so there is very little odor associated with their use |

Definition
| Position of the tool in relation to its section, determined by the angle at which the hair is wrapped |
|
|
Term
|
Definition
| Also know as protective base cream; oily cream used to protect the skin and scalp during hair relaxing |
|
|
Term
|
Definition
| Angle at which the rod is positioned on the head (horizontally, vertically, or diagonally); also, the directional pattern in which the hair is wrapped |
|
|
Term
|
Definition
| Refers to the position of the rod in relation to its base section; base placement is determined by the angle at which the hair is wrapped |
|
|
Term
|
Definition
| Relaxers that require the application of protective base cream to the entire scalp prior to the application of the relaxer |
|
|
Term
|
Definition
| Subsections of panels into which hair is divided for permwrapping; one rod is normally placed on each base section |
|
|
Term
|
Definition
| Also known as straight set wrap; perm wrappping pattern in which all the rods within a panel move in the same direction and are positioned on equal-sized bases; all the base sections are horizontal, and are the same length and width as the perm rod |
|
|
Term
|
Definition
| Perm wrap in which one end paper is folded in half over the hair ends like an envelope |
|
|
Term
|
Definition
| Perm wrap similar to actual technique of laying bricks; base sections are offset from each other row by row, to prevent noticeable splits and to blend the flow of the hair |
|
|
Term
|
Definition
| A process or service that rearranges the structure of curly hair into a straighter or smoother form |
|
|
Term
| chemical texture services |
|
Definition
| Hair services that cause a chemical change that alters the natural wave pattern of the hair |
|
|
Term
|
Definition
| Perm rods that have a smaller diameter in the center that increases to a larger diameter on the ends |
|
|
Term
|
Definition
| Perms in which the hair strands are wrapped from the ends to the scalp in overlapping concentric layers |
|
|
Term
|
Definition
| Perm wrap in which partings and bases radiate throughout the panels to follow the curvature of the head |
|
|
Term
|
Definition
| Perm wrap in which one end paper is placed under and another is placed over the strand of hair being wrapped |
|
|
Term
|
Definition
| Also known as piggyback wrap; a wrap technique whereby extra-long 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 |
|
|
Term
|
Definition
| Also known as end wraps; absorbent papers used to control the ends of the hair when wrapping and winding hair on perm rods |
|
|
Term
|
Definition
| Perm activated by an outside heat source, usually a conventional hood-type hair dryer |
|
|
Term
|
Definition
| Create an exothermic chemical reaction that heats up the waving solution and speeds up processing |
|
|
Term
| glyceryl monothioglycolate (GMTG) |
|
Definition
| Main active ingredient in true acid and acid-balanced waving lotions |
|
|
Term
|
Definition
| Base control in which the hair is wrapped at an angle of 90 degrees or perpendicular to its base section, and the rod is positioned half off its base section |
|
|
Term
|
Definition
| An acid -alkali neutralization reaction that neutralizes (deactivated) the alkaline residues left in the hair by a hydroxide relaxere and lowers the pH of the hair and scalp; hydroxide relaxer neutralization does not involve oxidation or rebuild disulfide bonds |
|
|
Term
|
Definition
| Very strong alkalis with a pH over 13; the hydroxide ion is the active ingredient in all hydroxide relaxers |
