|
|
Term
|
Definition
| absorbant papers used to control the ends of the hair when wrapping and winding hair on perm tools |
|
|
Term
|
Definition
| perm that creates an exothermic chemical reaction that heats up the solution and speeds up the processing |
|
|
Term
| glyceryl monothioglycolate (gmtg) |
|
Definition
| main active ingredient in true acid and acid-ballanced waving lotions taht effectively reduces the ph |
|
|
Term
|
Definition
| base control in which the hair is wrapped at an angle of 90 degrees(perpendicular) to its base section and the tool is positioned half off its base section |
|
|
Term
|
Definition
| relatively weak physical side bonds that are the result of an attraction between opposite electrical charges; easily broken by water, as in wet setting or heat, as in thermal styling and re-form as the hair dries or cools |
|
|
Term
|
Definition
| relaxers with a very high ph. sometimes over 13 |
|
|
Term
|
Definition
| process by which hydroxide relaxers permanently straighten hair; lanthionization breaks the hair's dissulfide bonds during processing and converts them to lanthionine bonds when the relaxer is rinsed from the hair |
|
|
Term
|
Definition
| perms that work at a low ph and use sulfates, sulfides, and bisulfites as an alternative to ammonium thioglycolate |
|
|
Term
|
Definition
| ionic compands formed by a metal (sodium, potassium, or lithium) combined with oxygen and hydrogen |
|
|
Term
|
Definition
| process of stopping the action of a permanent wave solution and hardening the hair in its new form by the application of a chemical solution called the neutralizer |
|
|
Term
|
Definition
| relaxers that do not require aplication of a protective base |
|
|
Term
|
Definition
| conditioners with an acidic ph that condition the hair and restore the natural ph prior to shampooing |
|
|
Term
|
Definition
| base control in which the hair is wrapped at an angle 45degrees below the perpendicular to its base section and the tool is positioned completely off its base section |
|
|
Term
|
Definition
| base control in which the hair is wrapped at an angle 45degrees beyond the perpendicular to its base section and the tool is positioned on its base section |

|
|
Term
|
Definition
| amino acid chains joined together by peptide bonds |

|
|
Term
