TYPES OF PERMS
What are the two types of perms
Alkaline and Exothermic
True acid waves have a pH between:
4.5 and 7.0
After consultation and the drape what is the is the first step in actually performing a perm?
Wash the hair with CLAIRIFYING shampoo
compounds made of carbon, oxygen, hydrogen, nitrogen, and sulfur
Amino acids
Concave rods have:
smaller circumference in middle than on ends.
Alkaline Waves or Cold Waves Alkaline waves, also known as cold waves, were developed in:
1941
Modern acid waves are actually acid-balanced waves, which are permanent waves that have a PH of:
7.0 or neutral pH
After the perm has processed what temp water should you use?
Warm water
chemical bonds that join amino acids together end-to-end in long chains to form polypeptide chains
Peptide (end) bonds:
Straight rods have:
consistent diameter
Alkaline Waves or Cold Waves Alkaline waves, also known as cold waves have a pH between:
9.0 and 9.6.
Most of the acid waves found in today’s salons have a pH between:
7.8 and 8.2
While wrapping the perm you should be using consistent _________ & ___________
tension and base placement
formed by peptide bonds linked together
Polypeptide chains
What are the three types of base placements?
On-base placement
Half–off base placement
Off-base placement
Which perm produces heat because of an oxidation reaction that results when the activation tube which contains hydrogen peroxide is added to the permanent wave solution
Exothermic Perms / Exothermic permanent waves
Which type of perms use an ingredient that does not evaporate as readily as ammonia, so there is very little odor associated with their use?
Ammonia-free
What do the 3 S's stand for?
Size of curl
Separation
And “S” shaping to the curl
middle layer of hair located beneath cuticle; responsible for hair strength and elasticity
Cortex
What type of perm wrapping is hair wrapped at an angle to form a coil (like the grip of a tennis racket)
Spiral
All exothermic waves have three components, which are:
permanent waving solution, activator, and neutralizer.
Which perms have the highest and lowest PH?
Highest(Alkaline) : Alkaline/Cold wave: 9.0-9.6 OR Exothermic Wave: 9.0-9.6
Lowest(Acidic) : True Acid Waves: 4.5-7.0
What are the 4 types of end wrapping techniques?
Book end
Flat wrap
Double flat wrap
Double book end
innermost layer of hair, often called pith or core; does not play a role in restructuring; missing in some types of hair
Medulla
What type of perm wrapping is when the hair wrapped from ends to scalp in overlapping concentric layers
Croquignole
