Perm theory
Chemical texture service that involves the process of using physical and CheMichal actions to permanently change the texture of hair
Perming
Wrapping the hair smoothly and evenly around each rod using appropriate tension to ensure the hair takes on the desired shape is what phase in perming
Physical
What are the two basic techniques used when perming
Overlap and spiral
What type of curl is made using the spiral technique
Elongated texture pattern
What perm pattern is Versatile and adapts to contours or curves of the head
Contour pattern
who invented the first permanent waving machine
Charles Nessler
What are the 2 chemicals used during the chemical phase of perms
Perm solution (reducing agent) and Neutralizer (oxidizing agent)
What type of curls are produced using the croquignole technique
Undulating curls
What is another name for Zonal perms
Partial perms
What perm pattern generally uses rectangle-shape and trapezoid-shape bases and are usually horizontally and diagonally placed depending upon the curves of the head
Bricklay pattern
What year was the croquignole method of wrapping hair from ends to scalp created
1926
Also known as waving lotion or reforming lotion
Perm solution
What is placing texture in one or more specific areas or zones of the head called
Texture placement
Adding texture only at the base to create lift and volume for added fullness
Base perming
What perm pattern Involves adding texture in certain areas or zones of the head and works well with short hair clients
Zonal pattern
What is the P.H of acid perms
6.9-7.2
Applied to reharden and fix hair into new wavy or curly shape, then thoroughly rinse
Neutralizer
What design principle repeats the same shape and diameter perm rod throughout the perm design
Repetition
What design principle is created when using rod diameters that can create a large-to-small or small-to-large texture pattern
Progression
What expands the form and can create the illusion of shorter lengths
Texture
What is the main ingredient of acid perms
Thioglycolic derivative
The ingredient Thioglycolic derivative is called
Glyceryl monothyoglycolic
The term used to refer to the way perm tools are arranged around the clients head while wrapping
Perm pattern
Generally considered the most basic perm pattern and can be performed on any sculpted form
Rectangle perm pattern
Name the five common perm patterns
Rectangle, contour, One-two bricklay, spiral bricklay and Zonal perm pattern
