Which chemical texture service requires a pre-service shampoo?

Back

permanent waving

Answer explanation

Permanent waving

This question focuses on the pre-service shampoo requirements for different chemical texture services, specifically permanent waving, chemical relaxing, and curl reformation.

Permanent waving is the correct answer because it requires a pre-service shampoo to cleanse the hair and scalp, ensuring that the waving solution can effectively penetrate the hair shaft. In contrast, chemical relaxing and curl reformation services do not require a pre-service shampoo, as they involve the application of relaxers and other chemicals that can effectively work on the hair without prior shampooing. Texturizing treatment is also an incorrect answer as it is a type of chemical relaxing treatment and does not require a pre-service shampoo.

Key Takeaway: A pre-service shampoo is necessary for permanent waving, but not for chemical relaxing or curl reformation services.

Which layer of the skin contains the hair follicle?

Back

Dermis

Answer explanation

Dermis

The hair follicle is located in the dermis, which is the middle layer of the skin. This layer contains connective tissue, blood vessels, and structures such as sebaceous glands and hair follicles, making it essential for supporting hair growth and maintaining skin health.

The epidermis is an incorrect choice because it is the outermost layer of the skin and does not contain hair follicles. Instead, it serves as a protective barrier and is primarily composed of keratinized cells.

The subcutaneous layer is also an incorrect choice because it is the deepest layer of the skin, consisting mainly of fat and connective tissue, and does not house hair follicles.

The medulla is an incorrect choice as well, as it is not a layer of the skin but rather the innermost layer of the hair shaft.

Key Takeaway: The hair follicle is located in the dermis, the middle layer of the skin, which plays a vital role in supporting hair growth and maintaining the structures necessary for healthy skin and hair.

Where should used linens, towels, and capes be placed after each service?

Back

In the laundry

Answer explanation

In the laundry

Proper hygiene and cleanliness are essential in a barbershop, especially when it comes to handling used linens, towels, and capes after each service. Ensuring that these items are properly stored and cleaned helps maintain a sanitary environment and prevents the spread of infections.

In the laundry is the correct answer because used linens, towels, and capes should be placed in the laundry for washing and sanitizing after each service. Placing them On the workstation counter or On the styling chair is incorrect as it can lead to cross-contamination and is unhygienic. Depositing them In a closed receptacle is also incorrect because this is where swept-up hair should be placed, not used linens, towels, and capes.

Key Takeaway: Always place used linens, towels, and capes in the laundry after each service to maintain a clean and sanitary environment in the barbershop.

What is the MAIN difference between adjustable-blade clippers and detachable-blade clippers?

Back

Blade changing mechanism

Answer explanation

Blade changing mechanism

This question focuses on the main difference between adjustable-blade clippers and detachable-blade clippers in the context of haircutting and styling safety precautions.

The correct answer is Blade changing mechanism because adjustable-blade clippers have blades that are affixed to the unit with screws and can be opened or closed by the adjustment lever on the side of the unit. In contrast, detachable-blade clippers allow for quick and easy blade changes by removing and attaching blades while the clipper is running. The incorrect choices are Power source, Cutting speed, and Clipper guard compatibility, as these factors may vary among different models and brands, but they do not represent the main difference between the two types of clippers.

Key Takeaway: The primary difference between adjustable-blade and detachable-blade clippers is the mechanism used for changing blades, which affects the ease and speed of blade adjustments during haircutting.

In which situations should you avoid forcing shear blades through a section of hair?

Back

When there is resistance

Answer explanation

When there is resistance

This question focuses on the proper use of scissors and shears during haircutting, specifically when to avoid forcing the blades through a section of hair.

The correct answer is When there is resistance because forcing the blades through resistant hair can damage the hair and the shears. The following choices are incorrect: During damp hair cutting because damp hair is generally easier to cut and does not pose a risk to the shears; While trimming split ends because trimming split ends typically involves smaller, precise cuts that do not require excessive force; and During shear-over-comb technique because this technique involves cutting hair in small increments while combing, which should not cause resistance if done correctly.

Key Takeaway: Avoid forcing shear blades through a section of hair when there is resistance, as it can damage both the hair and the shears. Instead, section off a thinner parting for cutting.

What is the purpose of using styling brushes during the shaving process?

Back

Control and style hair

Answer explanation

Control and style hair

During the shaving process, barbers use various tools and techniques to ensure a comfortable and precise shave for their clients. One of these tools is the styling brush, which serves a specific purpose in the process.

The correct answer is Control and style hair because styling brushes are used to manage the client's hair during the shaving process, ensuring it stays in place and is styled properly. The incorrect choices are: Apply shaving cream, which is not the purpose of a styling brush as shaving cream is typically applied with a brush specifically designed for that purpose; Remove excess lather, which is done with the barber's thumb or a towel, not a styling brush; and Soften hair cuticle, which is achieved through steaming and lathering the face, not by using a styling brush.

Key Takeaway: Styling brushes are used during the shaving process to control and style the client's hair, ensuring a comfortable and precise shave.
