When you shampoo a client's hair, your primary purpose is to:
|
cleanse the hair and scalp
The scalp and hair need to be cleansed prior to receiving most salon services. |
Shampoo selection requires assessing the:
|
condition of the client's hair
There are various hair and scalp conditions that need to be taken into consideration. |
PH levels are a measure of:
|
whether a solution is acid or alkaline
Acid solutions have pH from 0 to 6.9, and alkaline solutions have a pH from 7.1 to 14. |
Shampoos called "pH-balanced" are:
|
more acidic
Low-pH or acidic products are good for any hair--especially treated hair. |
The purification process for fresh water is done by:
|
sedimentation and filtration
Sedimentation causes matter to sink to the bottom, and filtration removes suspended material. |
Water is called soft or hard depending on the:
|
amount of minerals present
The degree of hardness or softness depends on the kinds and amounts of minerals present in the water. |
Shampoo's main ingredient is:
|
purified water
Water is usually the first ingredient listed. |
Surfactants are effective because of:
|
the surfactant molecule
The attraction between the hydrophilic "head" and the lipophilic "tail" creates a push-pull process that causes oils, dirt, and deposits to emulsify. |
The molecular process in surfactants works by:
|
lifting off oils and dirt into the water
The surfactant molecules' push-pull effect causes deposits to roll up into balls that lift off and can be rinsed off. |
The hair care product that accounts for the highest dollar expenditure is:
|
shampoo
Consumer studies show that the most vigorous growth is found in shampoos retailed through salons. |
In hair products that are acid-balanced, the pH is:
|
between 4.5 and 5.5
A shampoo can become acid-balanced by the addition of citric, lactic, or phosphoric acid. |
Conditioning shampoos help the hair with ingredients that restore moisture and elasticity and:
|
add volume
Protein and biotin are two agents that boost conditioning shampoos. |
In some cases, very strong, medicated shampoos:
|
must sit on the scalp for a longer period
These shampoos contain special chemicals or drugs that are effective in reducing dandruff and other scalp conditions. |
The acidic ingredients used in clarifying shampoos:
|
cut through product buildup
Ingredients such as cider vinegar cut through product buildup that can flatten hair. |
In some cases dry or powder shampoos are advisable, such as:
|
for elderly clients
An elderly client may experience some discomfort at the shampoo bowl due to pressure on the back of the neck, making a dry shampoo advisable. |
