Chemical Texturizing
Ch. 18 Chemical Texture Services
Term | Definition |
---|---|
acid-balanced waves | perms with a 7.8-8.2 pH range that process at room temperature; do not required hair dryer heat |
alkaline/cold waves | perms that process at room temperature without heat with a pH ranges between 9.0-9.6 |
ammonium thioglycolate (ATG) | main active ingredient/reducing agent in alkaline waves |
base control | the position of the perm rod in relation to its base section |
base cream | protective cream used on the scalp during hair relaxing |
base direction | angle at which the perm rod is positioned on the head; also the direction in which the hair is wrapped |
base relaxers | relaxers that require the used of a base/protective cream |
base sections | subsections of panels into which the hair is divided for rodding |
basic perm wrap | rodding pattern in which all the tools within the panel are directed in the same direction |
bookend wrap | perm wrap in which an end paper is folded in half over the hair ends |
chemical blow-out | combination of a relaxer and hairstyling used to create a variety of Afro styles |
chemical hair relaxing | the process of rearranging the basic structure of extremely curly hair into a straightened form |
chemical texture services | hair services that cause a chemical change that permanently alters the natural wave pattern of the hair |
crouignole rodding | rodding from the hair ends to scalp |
end wraps | end paper; absorbent paper used to protect and control the ends of the hair during perming services |
endothermic waves | perm activated by an outside heat source, usually a hooded dryer |
exothermic waves | perms that create an exothermic chemical reaction that heats the solution and speeds up processing |
glyceryl monothioglycolate (GMTG) | main active ingredient in true acid and acid-balanced waves |
hydroxide relaxers | relaxer with a very high pH, sometimes over 13 |
Ianthionization | process by which hydroxide relaxers permanently straighten hair |
lotion wrap | permanent waving wrapping technique in which the waving solution is applied to the section before rodding |
neutralization | process of stopping the action of a permanent wave solution and hardening the hair in its new form by the application of a chemical called a neutralizer |
no-base relaxer | relaxers that do not require application of a protective base |
permanent waving | a process used to chemically restructure natural hair into a different wave pattern |
pre-wrap solution | usually a type of leave in conditioner that may be applied to the hair prior to permanent waving to equalize porosity |
reformation curl | a soft-curl permanent; combination of a thio relaxer and a thio permanent, whereby the hair is wrapped on perm rods, used to make the existing curl larger and looser |
texturize | a process used to semi-straighten extremely curly hair into a more manageable texture and wave pattern |
thio relaxers | relaxers that usually have a pH of 10 and a higher concentration of ammonium thioglycolate than is used in permanent waving |
true acid waves | perms that have a pH between 4.5-7.0 and require heat to speed processing; process more slowly than alkaline waves and do not usually produce a firm curl |
