the dermal papilla
the hair bulb
the arrector pili muscle
the hair follicle
which of the following is a reason cosmetologists should understand hair and scalp properties
identifying the shape of hair follicles can help when recommending methods to make a client's hair grow faster
identifying the cause of a dry or oily scalp helps to better recommend medication to the client to alleviate the condition
identifying hair growth cycles and the differences between common and uncommon hair loss will help when recommending hair loss treatments to the client
identifying the elasticity of hair helps to better determine treatments to soften coarse gray hairs to match the texture of the client's pigmented hair
All of the following are living portions of hair that are below the skin surfaces EXCEPT _.
the hair bulb
the arrector pili muscle
the hair follicle
the dermal papilla
Which of the following can be a cause of dry hair and dry scalp ?
overactive sebaceous glands
inactive sebaceous glands
hair follicle growing out of the head at a perpendicular angle
absence of melanin
The ability of the hair to absorb moisture is hair _.
porosity
elasticity
density
saturation
Which sentence best describes the medulla ?
The medulla is the hair's outermost layer
The medulla is a cone-shaped elevation at the base of the hair bulb
The medulla is the hair's pith or core
The medulla is the fibrous protein layer of the hair
If a cosmetologist holds a strand of hair with one hand while sliding the other hand's thumb and forefinger from the end of the strand to the client's scalp, what component of the hair is being analyzed ?
porosity
elasticity
density
texture
Which of the following best describes how a disulfide bond in human hair is formed ?
Oppositely charged atoms in the hair are attracted to one another to form weak physical cross-ink side bonds
Amino acids are chemically bonded to each other , end to end , to form a polypeptide chain
oppositely charged atoms are attracted to each other to form cross-inked side bonds between adjacent polypeptide chains
Sulfur atoms on neighboring cysteine amino acids within polypeptide chains in the hair join
The hair , skin , nails , and glands are part of the _system.
epidermal
integumentary
endocrine
lymphatic
Which of the following is true about hair ?
Cutting hair makes it grow back faster and darker
Hair growth rate is determined by genetics
Scalp massages will increase hair growth
Gray hair is coarser than pigmented hair
The three different types of side bonds that link chains of amino acids together are _.
oxygen , hydrogen , and salt
hydrogen , ionic , and carbon
ionic, helix, and disulfide
hydrogen, salt, and disulfide
In which phase of the hair growth cycle does the follicle canal shrink and detach from the dermal papilla ?
Nitrogen phase
A long chain of amino acids linked by peptide bonds is called a _ chain .
amino-peptide
polymer
keratin
polypeptide
Which of the following is a situation in which a cosmetologist would allow the hair to cool before styling ?
when salt side bonds are being formed by changes in pH during chemical serving
when hydrogen side bonds have been broken by the heat from curling iron
when peptide bonds between amino acids are broken by a heat lamp during color processing
when disulfide bonds are converted to lanthionine bonds during servicing with a flat iron
which portion of the hair root structure supplies nutrients so that the hair can grow ?
the hair bulb
the dermal papilla
the arrector pili
the hair follicle
What is the outermost layer of hair
hair follicle
hair medulla
hair cuticle
hair cortex
Hair is approximately _ percent protein .
30
50
70
90

catagen phase
nitrogen phase
telogen phase
anagen phase

terminal hair
lanugo hair
vellus hair
anagen hair
Which type of hair has the largest diameter and usually requires more processing ?
terminal hair
coarse hair
medium hair
gray hair
What are the three growth cycles of human hair ?
anagen , growth phase, and telogen
catagen , return , and transition
anagen , catagen , and telogen
anagen , transition , and mature
Each of the following is a layer of the hair shaft structure EXCEPT _.
the cortex
the hair fiber
the hair cuticle
the medulla
Which statement best describes what may have happened to cause a client's hair to grow in a whorl pattern ?
The hair in the whorl has a raised cuticle , whereas the surrounding hair does not ,
The strands of hair in the whorl are oily due to overactive sebaceous glands
The strands of hair in the whorl are leaving the follicle at an angle different from the surrounding hairs
The strands of hair in the whorl are less elastic than the surrounding hair as a result of damage from a thermal styling tool
Which of the following conclusions can a cosmetologist make if a client expresses concern about not being able to grow the hair beyond shoulder length ?
The anagen phase of the client's hair growth is shorter than the anagen phase in other people's hair growth , so the client's hair will not grow any longer
The catagen phase of the client's hair growth occurs more quickly than that phase in other people's hair growth , so the client's hair stops growing
The clients has a larger amount of vellus hair than terminal hair , so the client sheds most hair strands before they can grow longer
The client has primarily lanugo hair , which is shed more frequently than vellus hair or terminal hair
