Relaxers
Chemical hair relaxers are made up of these substances
What are hydroxide and ammonium thioglycolate?
This type of perm solution should be used on a client who has fine brown hair
What is an acidic perm solution?
A longer matrix will produce this
What is a thicker nail plate?
Collagen and elastin are tissues made of this material
What is protein?
This is the part of the hair that is located above the epidermis
What is the hair shaft?
An example of a no-lye relaxer would be this
What is guanidine hydroxide?
The porosity and texture of the client’s hair would determine this
What is the pH level of the permanent wave application selected?
The proximal nail fold (PNF) and nail plate are sealed by this
What is the cuticle?
Sudoriferous glands perform these two functions
What are regulating body temperature and helping eliminate waste products from the body?
Coarse hair is most likely to have this
What is a medulla?
The process by which hydroxide relaxers permanently straighten hair, which is the reaction that removes one sulfur atom from the hair’s disulfide bond, is known as this
What is lanthionization?
This is the main ingredient of acid waves
What is glyceryl monothioglycolate (GMTG)?
Nail folds are defined as this
What are the folds of normal skin that surround the nail plate?
The skin’s pH level protects the body from these
What are pathogens?
Ninety percent of the chemical composition of hair is this material
What is protein?
Hydroxide relaxers typically have this type of pH
What is high pH, or alkaline pH?
This is the main ingredient of alkaline waves
What is ammonium thioglycolate (ATG)?
This is the hardened keratin plate covering the nail bed
What is the nail plate?
The layers of skin and fat from the outermost layer to the innermost layer are in this order
What are the epidermis, dermis, and subcutaneous?
Hair density measures individual hair strands in this area of measurement
What is 1 square inch of scalp?
Thio-based relaxers differ from hydroxide relaxers by adding this type of atom to break the disulfide bond
What is a hydrogen atom?
This type of perm solution produces heat and speeds up processing time
What are exothermic waves?
The nail bed and the nail plate are attached with a thin layer of tissue known as this
What is the bed epithelium?
These are the two types of pigment produced in an individual
What are eumelanin and pheomelanin?
The anagen phase is this phase of the hair cycle
What is anagen?
