Hair Follicle

Hair root

Anchor hair to the skin cells and is part of the hair located at the bottom of the follicle below the surface of the skin; part of the hair that lies within the follicle as its base, where the hair grows.

Hair bulb

Swelling at the base of the follicle tat provides the hair with nourishment; it is a thick, club-shaped structure that forms the lower part of the hair root.

Hair papilla

Cone-shaped elevations at the base of the hair located at the base of the follicle that fit into the hair bulb; the papillae are filled with tissue that contains the blood vessels and cells necessary for hair growth and follicle nourishment.

Hair shaft

Portion of the hair that extends or projects beyond the skin

Vellus hair

Also known as lanugo hair; short, fine, unpigmented downy hair that appears on the body, EXCEPT for the palms of the hands and soles of the feet.

Longer coarse hair that is found on the head, face, and body is:

Terminal hair

Anagen phase

The first stage of hair growth in which new hair is produced.

Catagen phase

Second transition stage of hair growth; in this phase, the hir shaft grows upward and detaches itself from the bulb

Telogen phase

Also known as the resting phase; the final phase in the hair cycle that lasts until the fully grown hair is shed

Temporary hair removal

Includes shaving, waxing, tweezing, and depilatories

Permanent hair removal

Includes methods such as electrolysis and laser hair removal

The process of removing hair from the follicle is known as:

Epilation

The technical term for the study of hair:

Trichology

What layer of the skin is the hair follicle located?

The dermis

About how many hair follicles can be contained within one square centimeter of skin?

A) 1000

B) 300

C) 100

D) 500

C) 100

Hirsutism

Excessive hair growth, typically affects women by causing dark hair to grow in areas of the body where men usually grow more hair, such as the face,arms, or back. Often a result of hormonal imbalances.

Hypertrichosis

Excessive hair growth which is genetically determined and can occur anywhere on the body in both men and women. The production of androgen plays no factor in the hair growth.

Hair that grows on the scalp is known as:

Capilli

Barba

Thick, coarse hair that grows on the face to form a beard

Eyelash hair is also referred to as:

Cilia

Supercilia is also known as:

A) eyebrow hair

B) peach fuzz

C) eyelash hair

D) all of the above

A) eyebrow hair

Lanugo

Soft, downy hair on the body at birth

Terminal hair

Thicker, pigmented hair that grows on areas of the body after puberty

Shaving

Usually performed by the client at home with an electric shaver, clipper or razor, removing hair from the surface of the skin. The hair usually grows back within 24-48 hours.

Chemical depilatory

A painless method of hair removal that dissolves the hair at the skin level.

May be used to remove unwanted hair from smaller areas such as the eyebrows, chin or around the mouth.

Tweezing

Waxing

One of the most requested for a of hair removal. Involves applying wax directly to the skin and then removing the wax and hair.

Soft wax

Also known as classic wax. The majority of waxing is performed with this type of wax because hair removal over large areas can be accomplished quickly and easily with this type of wax.

Hard wax

This type of wax is usually ideal for smaller areas and thinner, more sensitive skin. Applied to skin, allowed to harden, and then lifted with the fingers at one end and removed.

Threading

An ancient method of hair removal that is used widely in the Middle East, it is used to shape the eyebrows and remove hair from the upper lip and other facial areas.

Sugaring

A hair removal technique that originated in Egypt. A paste made primarily of sugar is applied to the surface of the skin in a rolling motion.

Electrolysis

A method of hair removal that requires the technician to insert a small needle into each hair follicle and alongside the hair until it reaches the root, it emits an electric or galvanic current that destroys the papilla and permanently prevents hair regrowth.

(Removal of hair by means of an electric current that destroys the hair root)

Galvanic electrolysis

Also called the multiple needle method, is a direct current (DC) utilized in electrolysis.

Thermolysis

Also known as the high frequency/shirt wave method

Blend (for electrolysis)

A mode of electrolysis that combines alternating current (thermolysis) and direct current (galvanic)

Laser

Uses wavelengths of light to penetrate and dismiss or destroy hair bulbs.

Photo epilation

Or pulsed light, uses a similar principle as lasers, but this type of light is not considered to be laser light. An intense pulsed light beams creates burst of energy used to destroy hair bulbs with minimal scarring.

Follicular canals are:

Lined with epidermal tissue. These cells produce he follicle and hair matrix.

Hair matrix

Where cell mitosis (division) happens.

Sebaceous glands:

Secretes the waxy substance called sebum, which lubricates the skin and hair. (OIL) helps keeps skin supple and waterproof and protects against external factors.

Arrector pili muscle

Contracts when affected by cold or other stimuli. It pulls on the follicle and forces the hair to stand erect causing goosebumps.

Basal cells are

Found within the hair bulb

Hair cuticle

The outer most layer of the hair shaft. (Hard keratin)

Hair cortex

The middle layer of the hair shaft. (Hard keratin)

The medulla

The center of the hair shaft or the innermost layer. (Soft keratin)

Sebum

A waxy substance found in the sebaceous glands that lubricates the hair follicle and the skin

How is hypertrochosis caused?

Can be genetically and ethnically inherited but can also occur due to natural life occurrences (puberty, pregnancy, and menopause), certain medical procedures, or certain medications. There is no cure but can be esthetically treated. It is NOT stimulated by male androgens.

How is hirsutism caused?

It is caused by excessive male androgens in the blood. This hormone imbalance can be caused by the stimulation of these androgens (puberty, meds, illness, and stress).

A disease is:

Is pathological, like conditions caused by viruses and bacteria, with a series o signs and SYMPTOMS.

A disorder is:

An abnormality of function, like a birth defect or genetically inherited malfunction.

A syndrome is:

Group of symptoms that , when combined, characterize a disease or disorder. (PCOS)

What is the difference between epilation and depilation?

Depilation removes hair at the skin level (shaving, chemical hair removal)

Epilation removes hair from the follicle (tweezing, IPL, waxing)

Sudoriferous glands

Sweat glands (WATER)

Pilosebaceous unit

Contains the hair follicle and its appendages, which include the hair root, hair bulb, hair papilla, hair shaft, arrector pili muscle, and sebaceous glands.

Axilla

the correct professional and anatomical term for the underarm;the region

between the arm and the thoracic wall

Candelilla

A hard wax used to modify the melting point and provide increased strength to hard depilatory wax

Carnauba

A hard wax used to modify the melting point and provide increased strength to hard depilatory wax

Depilatory

Substance, usually a caustic alkali preparation, used for temporarily removing superfluous hair dissolving it at the skin level.

Glabella (glow-bell-ah)

The area between the eyebrows at the top of the nose.

Gum rosin

An additive in soft wax

Rosin

A resin used in the manufacture of soft wax
