Question

question 1 (1 point)
the measurement that describes the number of individual hair strands on 1 square inch of the scalp is hair
o a density
o b porosity
o c elasticity
o d diameter

question 2 (1 point)
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?
o a the anagen phase of the clients hair growth is shorter than the anagen phase in other peoples hair growth, so the clients hair will not
grow any longer.
o b the client has a larger amount of vellus hair than terminal hair, so the client sheds most hair strands before they can grow long.
o c the catagen phase of the clients hair growth occurs more quickly than that phase in other peoples hair growth, so the clients hair stops
growing.
o d the client has primarily lanugo hair, which is shed more frequently than vellus hair or terminal hair.

question 3 (1 point)
which of the following is a reason cosmetologists should understand hair and scalp properties?
o a identifying hair growth cycles and the differences between common and uncommon hair loss will help when recommending hair loss
treatments to the client.
o b identifying the elasticity of hair helps to better determine treatments to soften coarse gray hairs to match the texture of the clients
pigmented hair.
o c identifying the shape of hair follicles can help when recommending methods to make a clients hair grow faster.
o d identifying the cause of a dry or oily scalp helps to better recommend medication to the client to alleviate the condition.

Explanation:

• Question 1: Hair density is defined as the number of individual hair strands per square inch of the scalp. Porosity refers to the hair's ability to absorb moisture, elasticity is the hair's ability to stretch and return to its original length, and diameter is the width of a single hair strand.
• Question 2: The anagen phase is the growth phase of hair. If a client's anagen phase is shorter, their hair will not grow as long. Vellus hair is fine, short hair, while terminal hair is longer and coarser. The catagen phase is the transitional phase, and lanugo hair is fine, downy hair present on fetuses.
• Question 3: Understanding hair growth cycles and hair loss differences helps cosmetologists recommend appropriate hair loss treatments. Elasticity is related to hair's flexibility, the shape of hair follicles does not directly affect hair growth rate, and cosmetologists do not recommend medication (that is typically a medical professional's role).

Answer:

• Question 1: a. density
• Question 2: a. 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.
• Question 3: a. Identifying hair growth cycles and the differences between common and uncommon hair loss will help when recommending hair loss treatments to the client.
