Chemical Texture Services Flashcards
Hair services that cause a chemical change that alters the natural wave pattern of the hair.
Chemical texture services
What do chemical services include?
permanent waving: Adding wave or curl to the hair.
Relaxing: Removing curl, leaving the hair smooth and wave free.
Curl re-forming (soft curl permanents): loosening overly curly hair, such as when tight curls are turned into loose curls or waves.
Tough exterior layer of the hair It protects the hair from damage.
Cuticle
Is responsible for the incredible strength and elasticity of human hair.
Cortex
Innermost layer of the hair may be missing in fine hair.
Medulla
An abbreviation used for potential hydrogen
pH
pH scale has a range from?
0-14
Permanent waves that have a 7.0 or neutral pH; because of their higher pH, they process at room temperature, do not require the added heat of a hair dryer, process more quickly, and produce firmer curls than true acid waves
Acid- Balanced waves
Also known as cold waves, have a pH between 9.0 and 9.6, use ammonium thioglycolate (ATG) as the reducing agent, and process at room temperature without the addition of heat.
alkaline waves
compounds made up of carbon, oxygen, hydrogen, nitrogen, and sulfur.
amino acids
Perms that use a ingredient that does not evaporate as readily as ammonia, so there is very little oder associated with their use.
ammonia-free waves
Active ingredient or reducing agent in alkaline permanents
Ammonium thioglycolate (ATG)
Postion of the tool in relation to its base section, determined by the angle at which the hair is wrapped.
base control
also known as protective base cream; oily cream used to protect the skin and scalp during hair relaxing.
base cream
Angle at which the rod is positioned on the head( Horizontally,Vertically, or diagonally); also, the directional pattern in which the hair is wrapped.
base direction
Refers to the position of the rod in relation to its bas section; base placement is determined by the angle at which the hair is wrapped.
base placement
Relaxers that require the application of protective base cream to the entire scalp prior to the application of the relaxer.
base relaxers
Subsections of panels into which hair is divided for perm wrapping; one rod is normally placed on each base section.
base section
also known as straight set wrap; perm wrapping 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.
basic permanent wrap
perm wrap in which one end paper is folded in half over the hair ends like an envelope.
bookend wrap
perm wrap similar to actual technique of bricklaying; base sections are offset from each other row by row, to prevent noticeable splits and to blend the flow of the hair.
